Pump for drip irrigation from the pool. Pump for increasing water pressure for watering the garden in the country. Where will the water come from

Garden pumps for watering provide a stable supply of water in the country and allow you to grow big harvest. Devices are different reliable performance and ease of use. Units can have a power of up to 1200 W and a capacity of 6000 l / h.

Features of the units

The watering pump is capable of sucking water from a great depth (8 meters), and pumping it. It is used not only for watering the garden, but is also a fairly effective device for pumping melt water. Fluid supply is carried out from wells and organizations of irrigation systems. The rise of water is carried out to a height of up to 60 meters.

It is possible to buy a garden pump with availability protective system overload motor. The devices emit minimal noise during operation and are quite easy to maintain. Switch electronic type prevents "dry running" with a minimum amount of water.

The main advantages of a garden pump

The main advantages of garden watering pumps include:

High mobility;
. convenience in everyday use;
. good water pressure;
. reliability and long service life;
. big choice modifications.

Due to the compact dimensions, it will not be any problem to carry a water pump for irrigation around the site and place the unit outside. With seasonal storage, the device does not take up much usable space. There are models with an electronic screen that will allow you to control the operation of the pump.

You can buy a pump for irrigation of various models that differ in power and performance at an attractive price in our online store.

During summer period summer residents have a hard time, because the garden requires constant care, and most of the work is done manually. The hot season is especially difficult, when you have to rush around with watering cans and water the plants daily. It is good if a central water supply is connected to the house, but not every dacha has such an opportunity. More often, the owners use wells or containers in which rainwater accumulates. But she herself will not run to the plants. It must be delivered. Carrying heavy buckets is unpleasant, and the spine will have a hard time. But the problem can be solved with special equipment– pumps. We will figure out what pumps exist for watering the garden and how to choose the right model for yourself.

Factors determining the choice of pump type

Irrigation pumps summer cottages there are many varieties. True, they were not created specifically for summer residents, but they have one thing in common - working with water. But the selection of the apparatus depends on what kind of water you are going to pump and where you will take it from. For plants, water does not have to be perfectly clean and transparent. They need warm, preferably settled water without harmful impurities and chemical production waste. The ideal option is rainwater, which the owners accumulate in different containers throughout the site.

Most often, water is taken directly from a well or well. But its temperature is quite cold, and if you constantly water the plants with such water, then many crops will begin to rot the root system (for example, cucumbers). To warm well water, summer residents raise it to the surface and let it warm up for several hours in some containers. And then they scoop it up with buckets and water it. According to the same system, water is also collected by residents whose summer cottages are located next to natural reservoirs. They collect it in barrels, stand for a couple of hours and then start watering.

If artificial reservoirs (a pond or a home pool) are provided in the landscape of the site, then you can use water to irrigate them. It will be warm, settled, but in this case the pool cannot be cleaned chemicals, otherwise all the "chemistry" will end up with vegetables on your table. This irrigation option provides a double benefit: you will periodically update the liquid in the reservoir and find where to put the old one.

Water in all these sources differs in the degree of pollution. And when choosing garden pumps for watering be sure to take into account the place from which the water will be drawn. For each source, separate types of surface, submersible, drainage and other units have been developed.

Parameters for selection of technical characteristics of the pump

In addition to the type of pump, it must be taken into account technical capabilities: power, performance, etc. To do this, you will have to analyze the following parameters in advance:

How many meters from the source of water intake to extreme point your garden.
How many meters is the height difference from the place where the pump will be installed to the extreme point of the garden.
How often do you plan to water your garden beds?
What area do you have horticultural crops requiring constant watering.
What type of irrigation will you choose (under the root, sprinkling, drip, etc.).

Now let's take a closer look at the most important points.

Performance calculation

If we take average indicators, then approximately calculate the characteristics of the pump as follows:

According to SNiP standards for irrigation of 1 sq.m. beds or flower beds take 3-6 liters of water per day (depending on the climate and soil conditions). So, if your garden area is 200 sq.m., you will need 200 X 6 \u003d 1200 liters. water per day. Accordingly, the pump must be able to pump such a volume of liquid in an hour, because no one wants to spend more time watering. You will find the performance of a particular model in the instructions or on the label on the device itself. It is denoted by the letter Q and in our case should be close to the numbers 1.5-2 cubic meters. in hour.

The second indicator is the height to which the unit can raise water from a river, well, well, etc. (i.e. pressure). The higher it is (in meters), the greater the distance can be between the pump and the water intake point. For example, if the maximum height of the model is declared as 40 meters, then your well or river cannot be more than 400 meters from the extreme point of irrigation of the site, since 1 vertical meter corresponds to 10 meters horizontally for hoses with a size of 1 inch.

The greater the distance or height from the water intake point to the beds, the weaker the pump performance, as the water head loss increases

Now let's do the calculations for specific example so that you understand what numbers you need to accurately calculate on the site before you go to the store for the pump. These calculations are suitable for any type of pump designed for pumping water from reservoirs, wells, wells.

For example, you plan to water the plot with water from a well located 30 meters from the extreme point of the garden. You will lower the pump to a depth of 6 meters.

We calculate the length of the pipeline: 30 + 6 = 36 m.
We make a allowance for pressure losses inside the pipeline and at joints, bends, etc. As a rule, it is 20% (0.2) of the total length of the hose or pipe. So, 36 X 0.2 = about 7 meters.
We add this figure to the height to which the water column must rise, in this case 6 m of depth, we get - 13 m.
In order for the pump to work without overloads, and the outlet pressure to remain within the normal range, another 10 m is thrown in. In total, 13 + 10 = 23 m. This will be the pressure recommended for these conditions of use, which is indicated in the instructions as H (height, pressure) . Thus, in this situation, pumps with H from 25 to 30 m can be selected.

The power of the motor will depend on the type of irrigation. For drip irrigation, low-power systems are used, and if sprinkling is used, then, on the contrary, systems are needed that can withstand high pressure.

Pumps for pumping water from tanks

Among all the devices, the pump for watering from a barrel is considered the easiest to maintain and connect. It is ideal for country purposes: it weighs little (up to 4 kg), works with containers whose depth does not exceed 1.2 meters, makes little noise and is easily fixed. They fix the pump directly on the barrel, insert the plug into the outlet - and start watering. You can expose yourself the right pressure jet with a pressure regulator. The pumps have a built-in filter that keeps out debris and solids, so you can immediately pour fertilizer into the barrel and start watering the finished solution.

Container pumps are lightweight and easy to install, so they can be moved freely around the site while watering.

But practice shows that built-in filters do not always completely stop particles of solid fertilizers that have not had time to dissolve. Even the most expensive systems will become clogged and need to be cleaned. But you can avoid this if you think of a home-made additional filter. They make it simple - old tulle. Look for a canvas that is larger than the volume of your barrel (so that the edges hang outward). The pump is immersed inside the tulle, and the edges of the material are tied to the edge of the container. There is no need to be afraid that the fabric will be pulled into the pump, because the motor is protected by a filter at the outlet. It will protect the system from sucking in the tulle, but problems with the technique will decrease.

Alternatively, you can hang the pump from a board placed on the tank so that it does not reach the bottom by 5 centimeters. Then all the rust and sediment will remain at the bottom, and will not go into the system.

The filter elements of the pump are located in the lower part of the housing, so sediment and fertilizer residues have every chance of clogging the system

On sale there are models with different power levels. If you have a garden allotted big square, then take pumps with a two-stage mechanism. Although they are more expensive, they are designed for large volumes of work and do not overheat during prolonged use. For several flower beds, a low-power device is enough.For example, such well-known manufacturers as Gardena and Karcher have not too many expensive options, the price of which starts from 2.5 thousand rubles. They are capable of pumping about 2 thousand liters. per hour, which is more than enough for small areas. If the area is large, then look for more powerful options. The maximum productivity of barrel pumps of these companies is 4 thousand liters per hour. For those who are looking for something cheaper, it is worth considering Belarusian pumps of the ZUBR brand. They all come with a float, they are similar in characteristics to Gardena, but the price is 1.5 times lower and the warranty is 5 years.

Most barrel units are sold without a hose, so it is more convenient to buy a kit. It immediately has watering hose(length - about 20 m), 2 nozzles, an outlet fitting and a spray nozzle, and in cheap devices, some spare parts will have to be purchased separately.

Important! If you choose a system with a float switch, then you will not have to control how empty the barrel is. The pump will turn itself off as soon as the level water will fall to the minimum. Accordingly, the risk of breakdowns during dry running is excluded.

Reservoirs + wells = surface pump

To draw water from wells with a shallow shaft or reservoirs (clean rivers, pools), surface pumps are produced. Their power is designed to lift liquid from shallow depths (not exceeding 10 meters). These pumps work on the surface (hence the name). The device itself is installed on the ground, and a hose is lowered into the pond. For such purposes, rubber hoses cannot be used, because during the pumping process rarefied air is formed inside the walls, and the hose is compressed, blocking the passage of water.

To connect the pump, you need to put it on a solid base and connect the hoses. But be prepared that the system will make a lot of noise during operation. You can suppress the degree of noise rubber mat, but if it is not there, then they hide the unit in some shed.

The advantage of surface pumps that take water from a reservoir or a well is that you do not have to move much for irrigation. Due to the powerful jet, you can irrigate about 40-50 meters, standing in one place.

When watering, it is necessary to install surface pumps on a solid base, and to make it less noisy, put a rubber mat

Many summer residents are wondering if it is possible to put such a pump on the site, and to pull long hoses to the source of water intake (i.e. the river), because some systems are quite heavy, and not everyone can carry them back and forth, and they can steal, until you get there. Definitely not. The maximum distance to the water is 9 meters (including the immersion of the hose). Such devices are not designed for more.

Of the two types (vortex and centrifugal), the first is designed only for clean water, which means that you can’t apply it in reservoirs. The second one is not so sensitive to impurities, and if it is equipped with an additional filter, it can also be pumped from a small river. The efficiency of the vortex one does not exceed 50%, but with similar characteristics to the centrifugal one, it will create 5 times more pressure, which (for example, by sprinkling) plays a decisive role.

Of the obvious advantages of surface pumps, one should note their ability to operate normally with frequent starts, i.e. you can turn off and turn on the watering gun without fear that the motor will burn out.

Drainage pumps - for polluted water bodies

If you plan to take water from a swamp, a pond, then it is better to give preference to a drainage pump. They are produced specifically for pumping heavily polluted waters, in which there is a lot of debris. The pump is equipped with filters and a chopper that grinds particulate matter almost to powder. For watering from a pond drainage pump it will fit perfectly, because it will not clog, and all the “good” picked up from the bottom (silt, shells, etc.) will be sent to your beds in a crushed state, thereby fertilizing them.

Drainage pumps are equipped with elements that filter and crush small particles, so they will not clog in highly polluted water of a natural reservoir or pond

But keep in mind that the pressure in such systems is weak, and you can only water by gravity. If you connect a nozzle, like a sprayer or a gun, then the water will not go at all. The best option use of drains - pumping dirty water into the container so that it settles, becomes cleaner, and even from the barrel it can be watered with a surface or submersible pump, providing protection against sediment from getting inside from the bottom.

When is the best time to buy a submersible?

If a well is punched in the area or a well is dug, then convenient option water intake from them will be a submersible pump. It is placed completely in the water, and the choice of a particular model will depend on how high it is able to raise the water column.

Weak-powered submersible pumps are designed for use in wells and reservoirs with sufficient depth. Most simple options- vibration models such as "Brook", "Spring", etc. They serve well when lifting water from a shallow well or a nearby reservoir, as they are immersed in water to a depth of 3 meters. At the same time, there should be at least half a meter from the beginning of the water mirror, so these pumps, unfortunately, are unsuitable for shallow water. The maximum height of the water column is 50 meters, which means that the length of the hose with a maximum immersion of 3 meters should not exceed 450 meters. The figure was calculated as follows: each vertical meter = 10 horizontal. 50 - 3 = 47 m; 47 X 10 \u003d 470 m. We subtract 20 meters for a margin so that the unit works without tension. The result is 450 meters of hose. If the distance to the river is greater - vibration pump won't fit.

O maximum height lifting water, it is easy to find information on the pump label: it is indicated Latin letter H and indicated in meters

With an average capacity of 20 liters per minute, you will pump out 2 thousand liters. in 1.5 hours, and if we take into account the pressure loss at the hose junctions, then this figure will be even less. Plus - take into account all the adapters if you connect the hoses. They reduce pressure, which means that the flow rate will decrease. As a result, Brooks and the like are quite suitable for watering under the root. But if you expect to use sprinklers, vibration systems will not work. They are too sensitive to pressure changes, and when overloaded, the motor quickly burns out.

Advice! Models with an upper water intake are more practical, as they have a reduced likelihood of silting and ingress of particles of sand and bottom sediment.

Some practical summer residents manage with "brooks" when watering from containers. They first pump liquid into the barrel, which heats up. And when necessary, they immerse the apparatus in a container and use it instead of a special barrel one. The only, but significant minus is a lot of noise. While you water, the neighbors will be forced to listen to the roar of the motor.

If the distance to the reservoir is more than 200 meters, then the most reliable will be submersible centrifugal pumps having a maximum head of 70 m and above. To organize the supply of water to the beds, lay the pipes PND32 or 40 to the beginning of the section, since it is not very convenient to unwind the hose to such a distance each time. Well, if you still use a hose, then only three-layer PVC 3/4 ″ with additional reinforcement. Simple Hoses can stick together due to pressure drops, and the system will stop functioning.

Watering hoses should be dense, layered and reinforced to withstand the rarefied atmosphere during irrigation and not stick together.

Borehole (or deep) pumps are difficult to install and maintain, and therefore require professional handling. In addition, they have to be dismantled for the winter. But if there is no other source of water on the site, then it is more convenient to pump water into containers with such a system, and then, heated, dilute it around the site with a less powerful and complex pump (the same surface or barrel pump).

Water from wells is always very cold, therefore, after raising it to the surface with a submersible pump, do not pour it directly on the plants, but let it warm up in containers

Drip irrigation: the best special equipment

The owners, who prefer to use water sparingly, water the gardens by drip. It saves time and doesn't waste water resources. For drip irrigation, there are special submersible pumps equipped with automation. The owner sets a certain mode on and, using a timer, sets the watering time. Everything else the system takes care of.

Such equipment is not cheap, but it frees the summer resident a lot of time that was previously spent on watering.

If you cannot find a pump with automation in one set, then you can buy a submersible pump and complete it with the necessary parts

However, practice shows that to create the necessary operating pressure any inexpensive pump can do 1-2 bar. Where the water comes from is another matter. You will not be able to take liquid from reservoirs without additional filter systems, as the built-in filter will quickly become clogged. Therefore, there remains either a central water supply, or a well, or a well. We have already considered the options for units for these sources of water supply above. True, it is worth adding that the most reliable type of pump for drip irrigation- centrifugal. Only he can give a large number of water throughout the day high pressure without overheating the motor.

To choose a pump with optimal performance, you need to figure out what your site will have hourly water consumption. They do it this way: they draw a grid of drip tapes on paper and calculate the total length of the water supply. Then multiply it with the number of droppers punched by 1 running meter. This figure will be the performance. For example, if you lay only 100 m of tape with 5 droppers per meter, then you will get 500 droppers. Each of them consumes an average liter of water per hour. Accordingly, the required pump capacity is 500 l / h.

When choosing pumps, it is not necessary to look for names famous brands. It is much more important to study their power, operating conditions and the level of popularity in your area. The latter will be needed in case of breakdowns of the unit: it is easier to find spare parts for popular models, and they are more readily taken for repairs.

Garden, garden, flower beds, lawns - everything needs regular watering. Conventional pumps for water supply do not always cope with this task - irrigation has its own characteristics, therefore the pump for watering the garden, garden, flower garden and lawn is chosen separately, using a completely different approach.

Water source and irrigation pump category

well;
well;
river, pond, pool;
containers and barrels.

In the case of a well and a well, the decisive ones will be specifications- it is necessary that water with proper pressure be delivered to the place of irrigation. Models - in principle, any. Choose to your taste.

If we are talking about a river, a pond or a pool, then the requirements for the degree of water pollution are added to the technical characteristics. If the water in the pool can still be considered relatively clean, then there will be enough pollution in the river or pond, so that conventional equipment will not work. Conventional models in this case will not work, as they are designed for clean water. Drainage and garden pumps can pump contaminated water. It is among these categories that you should look for a pump for watering the garden in this case.

When watering from containers and barrels, the task becomes even more interesting. The water in this case is also not clean, so drainage pumps are suitable, but not any, but the most low-power ones. It's all about the volume of water that can be contained in a barrel. With a high capacity of 200 liters of water, an average power pump will pump out in 1-3 minutes. During this time, you will have time to water quite a bit, but there is no more water. Therefore, the best in this case are the most low-powered (they are also the cheapest). Only when buying, pay attention that the pump comes with float sensor water level. If there is very little water left, this sensor will turn off the power.

Some companies produce special pumps for barrels. They just differ in low productivity and the ability to pump contaminated water, have small dimensions and weight, but at a price more expensive than similar drains. But the barrel pump for watering the garden is compact and lightweight.

By the way, solving the problem with quickly running out of water in a barrel is simple. There are usually several of them on the site. A little above the bottom level, you can weld fittings with taps and connect all the barrels with pipes. So it will be possible to pump water from all barrels without shifting the hose.

Types of pumps, their advantages and disadvantages when used for irrigation

Choosing a pump for watering a garden is not an easy task - you need to decide on many parameters, take into account the features of pumps and water sources. You need to choose such a “pair” so that it is convenient for you to water, and the equipment works in normal, not emergency mode.

Submersible

Submersible pumps can be used to pump water from any source of sufficient volume - a well, a well. It is problematic to pump from a pond and a river even with a sufficient amount of water - the water is not clean, and ordinary models feel fine only with it. With a very strong desire, you can make a filter chamber in which to place the pump itself. But this is also a controversial option - the walls of the chamber can be torn or clogged.

In wells or wells, both vibration and centrifugal submersible pumps can be used. The difference is that centrifugal ones can "deliver" water over long distances and lift it from great depths. Vibrating have more modest characteristics, a smaller resource, are more demanding on the purity of water, but their price is much lower. This explains their popularity.

There are different types of submersible pumps (vortex and vibration), they can work with different water– clean, dirty and very dirty

As for the river and the pond, they have already said that there are still containers left. You can’t put a centrifugal unit into a barrel or a eurocube at all - it will pump it out in a few seconds. Vibrating will create a very strong roar, even though it will take several minutes to “pull” water. But the noise is such that the neighbors can come. So it is also not very suitable for such working conditions.

So, for a submersible pump for watering a garden, it is suitable if the water source is a well or a well without sand.

Drainage

Drainage pumps are mostly of the submersible type. What distinguishes them is the ability to work with muddy and polluted water. In this regard, drainage pumps are used just for watering the garden from open water sources - rivers, ponds, etc.

But just remember that dirty water is not duckweed and mud, but water that contains solid particles no larger than 5 mm in size. But some manufacturers define other limits for their equipment - often the particle size should not exceed 3 mm. Therefore, if the reservoir is heavily polluted, the same chamber with mesh walls is required, which will trap large pollution. If you are reluctant to mess around with this, and the water is really dirty, you can use not a drainage pump for irrigation, but. He can even pump mud. There are models with a grinder that grind large objects that fall into it in seconds.

So, a drainage pump for watering a garden is good if the water has a significant amount of impurities, but they are all no more than 3-5 mm. For large pollution, it is more advisable to use a fecal aggregate.

Barrel

Another type submersible pumps, designed specifically for irrigation from small containers - barrel (barrel) pumps. They have low performance, low power and size, low noise level. When the water level in the tank decreases, they gradually raise the pressure so that the outlet pressure remains stable. In general, such a pump for watering the garden is a good purchase, but ... if the price suits you.

The inlet of the barrel pump is closed with a mesh - a filter from large contaminants. But this is not always enough. If there is a lot of dirt in the barrel, an additional filter is made. You can even lower a piece of gauze or other mesh fabric (old tulle, for example) into the barrel, fix it so that it does not reach the bottom a little. The unit can be lowered into this fabric. In this case, it will work longer without Maintenance(it is necessary to periodically clean from the dirt that accumulates inside). The fabric will not tighten inside during operation - there is a grid there, so the option is quite capable.

outdoor

Outdoor pumps are more suitable for watering a garden from a river or pond. Only the hose is lowered into the source, and the unit itself remains on the surface. Just keep in mind that the hose must be reinforced - the usual one will simply flatten the negative pressure created during operation.

The disadvantages of this type of equipment include their weight - they are usually quite heavy, which makes it difficult to carry. Their body is made of steel or cast iron, and it is clearly not light. To eliminate this drawback, special garden pumps were invented. Their body is made of plastic, which makes them much lighter - even a woman can easily cope with carrying. In addition, garden pumps are better suited for pumping not quite clean water. So for watering a garden from a river, this is a good choice.

Outdoor pumps are good for everyone, but filling them before starting work is not the most interesting activity.

There is one nuance in working with external suction pumps: in order to start them, you first need to fill the pump itself and the hose with water. An external pump for watering a garden can be, according to the method of operation, then you need to “refuel” a little - only the capacity in the pump, and this is several hundred milliliters. If the model is normally suction, the entire hose and capacity of the unit must be filled, and this may be more than a dozen liters. Since watering is a periodic action, it is tedious to fill such a system every time. Therefore, self-priming external pumps are used for watering the garden, or they are looking for something else.

There are external vortex (centrifugal) pumps, but they are only suitable for clean water. That is, this is another option for a well or well, but with a shallow depth. Their advantage is that they do not need to be filled in, although in terms of weight it is problematic to carry heavy ones from place to place.

Pump stations for watering the garden

If desired, you can use not a pump for watering the garden, but a pumping station. This is, in principle, perfect option- the pressure is stable, and it can be adjusted within a fairly wide range, while the motor is operating normally - it turns on and off. But not without flaws. Usually completed pumping stations surface pumps for clean water. They will have to be filled before launch, these are two. They are heavy - these are three. And the price is not always happy - it's four.

Pumping station for watering the garden - convenient, but not cheap

True, if you wish, you can assemble the station yourself, and on the basis of any pump (drainage, for example). You will need a pressure gauge and a five-pin fitting or a set flexible hoses with nuts of suitable diameters. You can also assemble the entire system on polypropylene or plastic, as you are used to. It's not that hard, so it's really easy to figure it out.

Requirements

When choosing a pump for irrigation, it is necessary to take into account the specifics of the operation of these devices. It is still significantly different from the usual working conditions that are used for water supply at home.

Performance

You can water the garden with any type of unit, but there is one caveat: the power must be selected so that when using nozzles (irrigation gun, sprinkler, etc.) the hose does not break off. And not the most pleasant moment is that with simple root watering, less productivity is required - a strong jet will simply wash the soil. When using sprinklers or irrigation guns, the pressure must be greater - in order to capture a larger area.

The only acceptable way out is to put a tee at the output of a pump of decent power. Connect a hose for irrigation to one outlet, and a hose through the valve to the second outlet, which will divert part of the water back to the source. With this connection, by adjusting the amount of water returned by the valve, it will be possible to change the irrigation pressure, and in a wide range.

Surface pumps for watering the garden in plastic cases are garden models, which were developed just for these purposes.

Such a system is very useful when watering from barrels. When using even conventional drains, barrels are pumped out very quickly. This water return trick allows you to stretch the flow and water a large area.

If you are looking for a pump for watering a garden with low productivity, you will find that the units good brands hard to find low power. If they are, then high price. But there are a lot of cheap Chinese low-capacity pumps, which are also designed for pumping dirty water. This is just the option that is needed for watering from a barrel, pond or river. True, their percentage of marriage is high - 20-30%.

There are two solutions in this case - buy a cheap pump, if necessary, buy a new one. The second way out is to reduce the productivity of a normal unit. This can be done by installing a smaller diameter hose at the outlet. But this is bad for the pump - it will work, but the wear rate will increase significantly. To improve working conditions, you can lead to the irrigation point with a regular-sized hose, and only then install an adapter. This is not something that will drastically improve the situation, but the water consumption will be less, and the pressure will be strong - you can use sprinklers and other nozzles.

Overheating and dry running protection

How does a garden watering pump work? long time, and even often not in the best mode for him, a situation is quite possible when the motor overheats. Therefore, it is very desirable to have protection against overheating (thermal relay). A very useful option - when the threshold temperature is reached, the power supply is simply turned off.

Any source of water can be scarce. Even from a well or a well, it can be pumped out. If the pump runs for some time without water, it will burn out - the water also serves to cool the housing. That's why they put it. The most popular, simple, reliable and cheap way- float. This is a water level sensor, which, if there is not enough water, simply breaks the power circuit. There are pumps for watering the garden that immediately come with such a device, and if not, you can install it yourself - by connecting the wires from the sensor to the break in one of the supply wires.

Defining parameters

As for productivity, we have already decided - it needs a small one - about 3-5 cubic meters per hour (this is 3000-5000 liters per hour), which is more than enough for watering the garden.

What will need to be considered is the pressure of the pump. This is the amount by which water can be pumped. The pressure usually consists of two components - vertical and horizontal. Vertical - this is the depth from which you have to raise water. Here, as it is, it is so - each meter of depth is equal to one meter of pressure. Only in the technical specifications for pumps is there such a line as “maximum suction depth”. So, it should be at least 20-25% more than the existing depth. You can take it back to back, but only branded equipment, since Chinese indicators are usually significantly overestimated.

The horizontal component of the pump head is the distance that the raised water will have to be transported to the irrigation point (when calculating, take the farthest point). When using inch piping or hose, it is considered that 1 meter of lift is required for 10 meters of horizontal piping. As the diameter decreases, the figure becomes smaller - for example, 3/4 inch counts 7 meters of pipe / hose per 1 meter of lift.

You will also have to take into account the resistance of pipes (hoses). To do this, add about 20% to the calculated value.

Example of pressure calculation. The water mirror is located at a distance of 6 meters from the surface, we will pump from a depth of 8 m, it will be necessary to transfer from the point of intake to 50 m. Trumpet goes inch, therefore we consider the horizontal head at 10 m.

So: the total head is 8 m + 50 m / 10 = 13 m. We add a margin for losses at the joints (20% of 13 m is 2.6 m), we get 15.6 m, after rounding - 16 m. When choosing a pump for irrigation we make sure that its maximum pressure is not less than this figure.

Every summer resident or amateur gardener knows how important the process of watering in the garden and personal plot. Fruit trees, flowers, vegetable crops, ornamental grass, bushes - all these plants need moisture. Actual solution are garden watering pumps. The device is simple and effective to use. But how to choose the right pump for the garden? What criteria should be followed when buying it?

Overview of pumps for irrigation in the garden

A garden pump may depend on the source of the water supply.

Irrigation equipment classification:

deep;
surface;
from a container (barrel);
drainage.

To choose suitable option it is for your site that you should decide where the water will come from, as well as take into account the preferences of plants. Cultures love settled and non-cold liquid. It is especially important for plants to receive rain water. It can be collected in containers: barrels, basins or buckets, then water the beds.

In gardens and summer cottages, there are excavated pools and. The water change will be helpful for artificial reservoirs. If they don't clean chemicals, then watering from pools and ponds is allowed. Some plots are located near a river or other body of water, and gardeners use them to irrigate their land. Based on where the water comes from, and choose a pump for the garden.

Also summer residents build wells from which watering can be carried out. For this type of water extraction, it is better to purchase a pump. This will make the whole process easier.

What should be garden pumps?

All pumps are designed to pump water. Some are used for a permanent supply of liquid (water supply in the house), while others are used for temporary watering of the garden. When choosing a unit, it is important to pay attention not only to the popularity of the brand, but also to the power of the pump, the availability of replacement parts for it on the market, and the operating rules.

The irrigation device should be as compact as possible, small size and weight. If necessary, it can be easily moved from place to place. It should not be difficult to install, install and operate. If there is an irrigation process, then it is better to choose garden pumps equipped with a pressure switch, a pressure gauge and a hydraulic accumulator. These elements allow the unit to operate in maximum mode without the participation of human forces.

Types of pumps for irrigation from a well, their pros and cons

Pumps for watering the garden from the well are installed on the surface or. How are they different?

The surface may be in small room located near the well. For this method, a hose is used - one end, which is connected to the pump, and the other is lowered into the water. Also, this unit is installed on the surface of the well liquid. To do this, construct a float that will keep the pump close to the water.

Surface devices are affordable. Their popularity is very high due to the fact that they are easy to operate, maintain and install. The main thing is to install it on a flat rubber surface. The suction depth of the pump does not exceed ten meters. The pressure allows you to squeeze the jet to a distance of 30 to 50 meters. This is a high performance that allows you to cover large area vegetable garden. But surface pumps have one drawback - they are very noisy. Therefore, they are placed in sheds or other outbuildings and installed on rubber mats.

The choice of submersible units is currently very wide. They are made of waterproof materials, they can be lowered into the water to any depth. The main thing is not lower than one meter from the bottom of the well. If this rule is neglected, then the quality of the water supply will deteriorate due to the ingress of sand and silt into the hose. The deep apparatus is valued for its good suction pressure, and it is also not exposed to moisture.

But submersible pump has its own negative sides. They should only be installed and serviced by specialists. Also, the device is not cheap, and requires certain conditions storage during the winter.

Barrel pumps for watering the garden

Based on the preferences of plants for irrigation, barrel pumps for watering the garden are the most suitable. Fruiting trees and bushes, vegetable crops require settled and warm liquid. Watering cold water(for example, from a well) can lead to rotting of the plant and slowing down its growth. Therefore, artificial pools and ponds are being built in the gardens. Barrel pumps are used to pump water from them to the site.

What is the advantage of such a pump?

firstly, it has fasteners, with the help of which it is fitted on the walls of reservoirs;
secondly, the pump is small in size and weight, which makes it easy and convenient to carry it around the site;
thirdly, the irrigation device has high level head: from 20 to 25 meters;
fourthly, water capacity up to 3000 liters;
fifthly, the automation of the unit, thanks to such a system, you can choose optimal mode glaze;
sixth, the presence of a filter, which allows the pumping of even untreated liquids, or fertilizer solutions;
seventh, the cost of the pump is low;
eighth, low noise level.

Among summer residents and gardeners, two-stage barrel pumps for watering the garden are very popular. They are durable in use.

Drainage pumps for watering the garden

Drainage pumps for watering the garden are used for pumping very dirty water: for example, from natural reservoirs - lakes or rivers. Such devices are not afraid of garbage. The pumps are equipped with choppers capable of handling leaves or mule. Drainage unit - optimal solution for polluted waterways. The grinder cuts grass and silt into small pieces and brings them out together with water. This allows the soil to receive additional mineral fertilizers. Other types of pumps will not be able to work with dirty water, as they will constantly be clogged, and as a result will be under repair.

Rules for choosing pumps for summer cottages - video

Owners of summer cottages every summer face difficulties associated with the need to water gardens and backyard lawns. The labor intensity of this lesson can be significantly reduced using special equipment - an irrigation pump, which we will talk about in this article.

We will talk about the types of water pumps, their technical characteristics and features of choice, as well as provide an overview of the most popular models from the world's leading manufacturers of such equipment.

1 What should be considered when choosing a pump?

There are many varieties of irrigation pumps, which differ not only in technical characteristics and productivity, but also functional purpose. The nominal purpose of the equipment is what kind of water you will pump, and is the main criterion for its selection. Since ideally pure water is not needed for watering plants, many gardeners use rainwater or technical, previously used water, which is not perfectly clean and contains mechanical particles. The same applies to water coming from a well or well.

This factor puts forward the main requirement for garden pump— the ability to work with contaminated liquids. Equipment for domestic use classified into varieties based on the type of working environment, according to this classification, drum pumps, drainage, surface and submersible units are distinguished.

In addition to the type of pump selected according to the source available on the site, it is necessary to take into account the technical characteristics of the equipment. Before buying, you need to decide on the following initial data:

distance from the garden to the extreme point of water intake;
the presence of a height difference in a straight line between the water intake point and the watered area;
the planned irrigation area, on which the choice of unit productivity directly depends;
type of irrigation - drip, sprinkling, under the root.

Irrigation performance, according to SNiP standards, should be 5 liters per m 2 of territory during the day. Depending on the air temperature and the condition of the soil, this number can vary between 3-6 liters. It is desirable that daily rate with manual watering, it was carried out within an hour, which will eliminate unnecessary waste of time. That is, for a garden or garden with an area of 100 m 2, a pump is needed that pumps an average of 500 l / h. Performance is always indicated in technical instructions unit. The designation can be made in cubic meters, 1 cubic meter = 1000 liters of water.

1.1 How to choose a pump for watering the garden? (video)

1.2 Calculation of the required head (power)

The head of the pump determines the height to which it can lift liquid from the well, and the maximum distance the water can be pumped. One meter of vertical water lift always equals 10 meters of horizontal transport (assuming inch hoses are used). Based on this, a pump designed for a height of 30 liters will be able to pump water over a distance of 300 m.

Let's calculate the required power of the equipment using a specific example. Initial data - the height of the water intake is 5 meters and the distance from the garden to the well is 40 m:

We determine the required length of the pipeline: 40 + 5 = 45 m.
We calculate the additional length of the pipes necessary to compensate for the loss of water pressure, it will be 20% of the total length of the pipeline. In this case - 45 * 0.2 = 9 m.
Add the resulting length in the height of the water intake: 5 + 9 = 14 m.
We add 10 m of pipeline as a power reserve, this is necessary to ensure the normal operation of the equipment, without overloads and pressure surges. We summarize the data: 14 + 10 \u003d 24 m.

As a result, the calculation showed us that for this case, a unit with a minimum water intake height of 24 meters is needed.

2 Classification and types of pumps

Irrigation equipment, depending on the principle of operation and the source of water intake, is classified into 5 main varieties

barrel;
superficial;
drainage;
submersible;
drip irrigation pumps.

Let's consider each class of equipment in more detail.

2.1 Barrel units

The barrel pump for watering the garden is designed to work with small storage tanks - barrels, settling tanks, eurocubes. Such equipment has a compact size, its weight rarely exceeds 4 kg. The barrel pump is equipped with low-power vibration motors, which, on the one hand, reduces its price, and on the other hand, limits the maximum level of water intake by 1-1.2 meters.

Like more advanced systems, the barrel pump has mechanical filter, which allows it to pump moderately contaminated liquids. Among the advantages of this equipment is the minimum noise level during operation, affordable cost. Proven models - Gardena 4000/2, Karcher BP-1.

2.2 Surface and submersible units

A surface pump for irrigation is needed when using a well or a well as a source of water intake, it is also possible to pump water from a pond or river. The power of this technique is enough to lift water to a height of up to 10 meters, while the equipment itself is installed on the surface, and an intake hose is lowered into the source.

Note that the length of the intake hose should not exceed 9 meters (including the vertical immersion height), so it will not work to install the pump on the site and throw a long hose to a reservoir or a well. The only significant drawback of such equipment is the high noise level during operation, the advantages are sufficient power for any purpose of domestic use and reliability when working on frequent starts.

There are two types of surface aggregates - vortex and centrifugal, the differences between them are in the principle of operation. Whirlpool equipment is designed for pumping clean water, while it is capable of delivering a higher flow head at the same motor power, while centrifugal equipment is focused on working with contaminated water, this the best choice when watering from a pond or river. Recommended vortex model - Gardena 3000/4, submersible - Karcher VR-3.

The submersible pump is an alternative to surface equipment. During operation, it is placed inside a well or a well and draws water directly through the suction pipe in the housing. Depending on the design, the branch pipe can be located below or above the body, last option preferred due to less risk of silting.

The submersible pump can be equipped with a vibration or centrifugal motor. Vibration engines are low-power, but cheap, while centrifugal drives are equipped with productive and rather expensive units, such as Karcher BP-6 DW.

2.3 Drainage units

It makes sense to choose a drainage pump for watering gardens if a polluted pond or well is used as a source of water intake. Such equipment is designed specifically to work with a liquid containing a large amount of mechanical impurities.

From other types of equipment, drainage units differ in that, in addition to mesh filter they have a grinder (knife shaft) that grinds all the debris contained in the water, thereby eliminating the possibility of clogging the body. However, there are also negative differences, namely a relatively low level of pressure, due to which it will not work to use a drainage pump for irrigation by sprinkling. The SP line of drains from Karcher, namely the SP-1 and SP3 models, has proven itself well.

2.4 Equipment for drip irrigation

The pump for drip irrigation can be anything - submersible, barrel or surface. Ideally, it should be equipped with a pressure switch and a timer, through which you can set the required pressure and water supply time. This makes it possible to arrange the system automatic watering, significantly reducing the labor costs of caring for the garden or garden.

However, the calculation of such equipment is somewhat different from that considered by us earlier. Here you need to determine the total length of the drip pipeline and determine the number of droppers. Since a standard size dropper consumes an average of about 1 liter of water per hour, their amount will be the required pump performance. The model recommended for purchase is Octopus MPC-3, DP750A.
