How much water pressure is needed to water the beds. Irrigation pumps - varieties and recommendations for choosing. When is the best time to buy a submersible

Own greens, cucumbers, tomatoes and other vegetables are not only tasty and without chemicals, but also very troublesome. Not to mention the planting, after which the back hurts, cultures need regular care and watering. If a bed overgrown with weeds is at least smaller, but disfigures, then you definitely won’t take anything with a dried one. Of course, you can carry buckets of water, but not everyone has enough health, and if you throw a hose to the water supply, an astronomical bill will come at the end of the month. So hardworking business executives are forced to look for an alternative, for example, submersible pumps that allow pumping water from almost anywhere.

Technical part

Submersible pumps are the most popular type of irrigation equipment. The working part is immersed in water, some models can sink almost to the very bottom and completely empty the containers. Water or other liquid is supplied under pressure to the surface through long hoses. Unlike surface ones, submersible ones are able to overcome a greater distance to the garden with practically no loss of pressure. This is convenient, because the source is not always located within walking distance. Depending on the variety, the outer shell of the units can be made of high-strength plastic or stainless steel. Whatever the material, it is designed for constant contact with the working environment.

Characteristics

Submersible pumps outperform surface counterparts due to their impressive performance.

• Silent- being in the water column, the pump practically does not make characteristic sounds, its operation is accompanied by a light, almost inaudible rumble.
• Powerful- able to supply water from great depths.
• Reliable- unlike surface units, all working parts are in water, which cools the system. When in the summer the thermometer goes off scale for +40 in the shade, this is a huge advantage.
• Universal- several subspecies are produced, designed for different environments of use.
• unpretentious- can work as clean water, and with varying degrees of pollution, up to sewage.
• Available- are cheaper than analogues designed for location above water.

According to the principle of water supply, submersibles are of two types:

Operating parameters of submersible pumps:

• Lifting height - up to 80 meters.
• The working environment is a liquid of any degree of contamination.
• Efficiency - almost 100% due to direct feed.

Features of submersible pumps depend on their variety:

• Well. designed for medium depth (15 - 40 meters), can be of solid diameter, equipped with a float system that turns off the unit if the water level drops.
• deep()- supplies water to 80 meters, gives the strongest pressure. Limited in diameter, it is a long, narrow cylinder.
• drainage- works in any water, equipped with a chopper, which will turn water debris into fertilizer for the garden. Also equipped with a float. you can read more about drainage pumps for summer cottages.
• Barrel (capacitive) – compact models low pressure, these are intended from barrels, tanks or buckets. They can even empty swimming pools. equipped with a bracket for fixing on the walls of the tank and a float for level control. In addition, it is possible to improve them with automation, which will set the irrigation mode. Submersible pump for rain barrels.

There are no particular shortcomings in this type of equipment. The only inconvenience is that they will have to be dismantled in the cold, unless a well or well supplies water to the house and is not protected decorative house. Many sources position submersibles as difficult to install, but this is not entirely true. Being able to read and having more or less working hands, it is quite possible to launch it on your own, following the instructions. And if you look at the information on the net, you can definitely do without the expensive services of professionals.

It is also worth noting that cheap models, such as the well-known "Kid" or "Brook", are susceptible to voltage drops in the network. But these are vibrational models; no such sin has been noticed behind centrifugal ones. You can read more about electric water pumps for irrigation.

In general, technical flaws usually appear as a result of improper handling. If the pump is designed for clean water, and lowered into rain water, with sand and leaves, it will clog and burn out. And it will not be the manufacturer's fault, but not the overly zealous owner.

How to choose

When choosing a model of a submersible pump, they proceed from the needs and conditions of its use.

• lifting height- naturally, if the water is at a great depth, this indicator will be the main parameter. Water not only needs to be raised, but also delivered to the site, these meters are also taken into account.
• Power- the number of liters supplied per minute or per hour is important when you fill the pool and want to faster. And when it comes to watering, too powerful model more of a hassle than a benefit. The splitters will be torn off by a strong pressure, and such a jet can do harm to plants.
• Source- at least important parameter. If it is quite realistic to attach a pump to a well, then it will suck out the barrel in a second and burn out, washing away all the plantings with pressure. But the well, with all the desire, simply does not fit in the well. If there are several sources, it makes sense to choose more universal model. For example, it is really possible to use a drainer in a well, and in a pond, and in a barrel.
• Water quality- if the water in the well and well is almost clean, there should definitely not be leaves with shells, then there are a lot of surprises in the pond. Yes, and in a barrel from the drains can attack all sorts of different things. Assuming watering from a pond or containers, you should not rely on chance and buy a pump for clean water.

When choosing a pump, you should not overpay money due to the fact that the expensive one pumps 4000 liters, not 3000. In practice, such a difference will be almost imperceptible, but a strong unit “eats” energy immeasurably.

Manufacturers and prices

• QUATTRO ELEMENTI is an Italian company offering big choice pumps. Acceptable quality, impressive performance and attractive price - drainage from 2000 rubles, vibration from 1500 rubles.
• HAMMER is a German concern specializing in tools, power and garden equipment and pumps. The quality of the Germans is unrivaled, and the cost is affordable, a vibrating submersible model from 2000 rubles, and a drain from 3000 rubles.
  
• Vortex - Russian manufacturer pumping equipment and household power tools. They produce various types of submersible pumps with a metal or plastic case, depending on the type. A drainage can be bought for 3,000 rubles, a well is more expensive - from 6,000 rubles.
• PATRIOT is one of the oldest American brands producing decent equipment. The quality of the company has been tested by generations, in our country their chainsaws are most famous, but the pumps are not inferior in any way. The drainage unit costs from 3000 rubles.

Submersible pumps are universal equipment, one pump is able to solve several problems: water the garden, empty the container, and pump water from the pond into the tanks. And such functionality costs a reasonable amount.

For summer residents, the issue of water supply is always one of the most relevant, which is why a pump for irrigation from a barrel can be a solution to many problems. All horticultural crops need timely saturation with vital moisture, because no living organism on our planet can exist without water.

Irrigation pump from a Karcher barrel

What is a barrel pump?

As you know, for irrigation it is undesirable to use very cold water, because vegetable and fruit crops may respond poorly to low temperature. That is why summer residents use various containers to accumulate water and then heat it up to an acceptable level. Previously, gardeners scooped up water with buckets or watering cans directly from the cistern, and thus watered the beds and other plantings. Such a process required high costs time and effort. Today, technological advances have advanced far, and such a thing as a barrel pump for watering the garden has facilitated the work of many owners. summer cottages. This practical device is a kind of water pump that can pump water from a barrel or tank. The pump is compact in size, has good water pressure, and is easy to operate. In this it differs from high-power units for pumping water of a surface or submersible type.

This option is great solution for suburban areas that are not connected to a centralized water supply. The principle of operation of the device is simple: a pump is installed on the tank, which takes (pumps) water - this is how watering is done.

The unit has a small weight (usually up to 4 kg), it is easy to reinstall it from one tank to another, it does not produce much noise during operation.

It can also be used to irrigate - add water-soluble fertilizers directly into the tank. To play it safe and protect the device from clogging with solid particles “sliding” into the system, you can additionally install a home-made filter on the tank.

For these purposes, tulle or dense gauze fabric is quite suitable, which in size should be more volumes water tank. It is placed in a container, the free edges are securely fixed on the barrel, then the pump is immersed directly into the fabric bed. You should not be afraid that during operation the unit will draw in the fabric, because the "heart" of the system is equipped with a "native" filter at the outlet. Often experienced summer residents go for additional tricks - they lay a strong board on top of the container, to which they hang a pump for watering from a barrel. At the same time, it should not reach the bottom by about 10 cm. Various debris and sediment always accumulate at the bottom, but after such manipulations, the likelihood that rubbish will not enter the system increases significantly. Devices of this kind are designed to work with tanks whose depth does not exceed 1.2-1.5 meters.

How to choose a pump for irrigation from a barrel?

First you need to assess the scale of the proposed work, namely, the area of ​​\u200b\u200bthe garden / garden. If service is planned large area, then it is better to opt for a unit with a two-stage mechanism, which is designed for long work so it won't overheat.

If you have a small garden and flower garden, you can take a pump with low power. The most popular and well-established are the models of the brands Gardena, Sterwins, the pump for irrigation from the Karcher (Karcher) barrel, as well as the Belarusian ZUBR units. famous German quality brands Karcher and Gardena presents to your attention both expensive systems and quite budget ones (from 2500-3000 rubles). The so-called "inexpensive" pump is capable of pumping about 2000 liters of water in 1 hour, this is quite enough for a small or medium area.

Well, if your garden or garden has an impressive size, then you will need a more powerful device. Keep in mind that maximum rate The efficiency of pumps of the brands Karcher and Gardena is 4000 liters of water in 1 hour.

When choosing a model, also pay attention to the presence of a float switch - this is a very convenient feature in which you do not have to control the water level in the tank. Thus, protection against "dry running" is provided, and the risk of associated breakdowns is minimized.

According to the reviews of summer residents, the pump for watering the garden from a container from the Belarusian ZUBR brand has proven itself well. Whole the lineup of these units is equipped with a float, has guarantee period 5 years, technical characteristics are in many respects similar to representatives of the Gardena brand, while their cost is 1.5-2 times lower than the German counterpart. Some models come with watering hose, nozzles, as well as with a fitting and nozzles for spraying.

More budget options require additional equipment.

Also, submersible and surface pumps can be used to draw water from barrels (large containers). Submersible, as the name implies, are immersed in a tank of water. Surface units draw water using suction hoses.

What you should pay attention to when choosing a unit:

• body tightness (sealing rubber bands);
• impact resistance of the case (what material it is made of);
• fastening on the body (to make it convenient to fix the device on the barrel), a bracket for fixing the hose on the edge of the tank;
• a float for determining the water level, which was already mentioned above;
• manufacturer's warranty.

As practice shows, as well as numerous reviews of the owners, for gardening needs, the most optimal in terms of power is pump for watering from a barrel of 200 l. For watering one square meter land, on average, about 5 liters of water are used - based on this indicator, one can approximately calculate the pump performance. The required power of the unit (as well as the water pressure) can be determined based on the distance over which the irrigation hose will be pulled.

Barrel drip irrigation pump

Separately, it is worth mentioning a convenient and rational way of watering - drip. This method allows you to save not only water supplies, but also your time. For the organization of drip irrigation, it is recommended to use a submersible pump with automatic regulation of the water supply. Of course, this unit is more designed for pumping water from a well or well, but it is also suitable for barrels and water tanks. You personally set the required mode on the pressure switch, in this case - the minimum. Also, using the timer, the frequency of watering is set, the rest is the operation of the system. If you study the information in the relevant forums and listen to the advice experienced summer residents, it becomes clear that it is the centrifugal submersible pump that is the most the best option for drip irrigation.

The pump for drip irrigation from a barrel will be able to supply water for a long time (at the right pressure) without the threat of overheating of the pump motor. Of course, the matter should be taken seriously - carefully calculate the water consumption over time, draw up a drawing of the drip tapes, taking into account the total length of the water supply. It is also necessary to take into account the number of holes (droppers) per 1 running meter. For example, I will give a calculation: you lay 100 m of a hose (tape), there are 6 droppers for each meter, as a result we get 600 droppers, each of which produces 1 liter of water for 1 hour. Therefore, you will need a pump with a capacity of 600 l / h.

Irrigation is an important part of garden maintenance. Summer residents devote a lot of time and effort to this type of work. They come to help different systems irrigation, which, by the way, effectively and stably supply water to the summer cottage. A garden watering pump is an invention that helps solve many problems. dacha problems. Today we will look at different pump systems and try to decide which one to choose is better.

So, there are several types of water pumps, which are classified based on the method of extracting water: a well, a well, a barrel or an open reservoir. Based on the above, there are two main types of water pumps: submersible and surface. Respectively, surface devices those summer residents who extract water from the bottom of a well or well will choose. Also, if the site is located near a river or pond. Such a pump is designed for pumping water from a depth of up to 10 meters.

Submersible water pumps are not as often used on the farm as surface ones. But if it happened and the water level in the well or well is below 10 meters, then this is the only correct option. Submersible pumps are designed to a depth of 40-80 meters. Not often summer residents choose this type of water supply because complex system installation.

But the easiest in terms of installation and installation is a barrel pump. A feature of such a system: water is pumped from a barrel or any container. The main thing is that the station does not overheat. According to the method of collection - homemade.

For those who do not like to water the garden or garden for a long time, there is an automatic or drip water pump. Such systems are equipped with a winding timer, which allows the owner of the summer cottage to stay away from him. You can build something like this yourself.

When choosing the type of device for your summer cottage, consider the quality of the water you will work with and the place where the water station is located. Small debris can ruin a device that is not intended for pumping water, for example, from a swamp. Often, springs require drainage filtration due to the low quality of the water.

Having considered the different types of water pumps, let's talk about the two main ones - surface and submersible.

Video “Selection, piping and installation of the pump in the well”

Surface

This type of water pump is usually located on the surface of the earth, the water is supplied from a water intake hose. Hoses, in turn, pump water from a well or well. Attached to the other side metal pipe. With such a water supply system, it is better not to use a hose made of rubber. Since rarefied air is formed in the hose, due to which the walls are compressed and the normal flow of water is disturbed. A big advantage of this system is the ease of installation. The unit must be placed on a flat, dry surface and then the hose must be connected. Another advantage is the powerful water supply, from one source you can water a large part of the garden. Their plus is that this type of system is self-made, you can not resort to the help of professionals. Surface pumps are also used for drip irrigation.

Submersible

Submersible devices are used if the water level in the source is below 10 meters. Such a machine is lowered below the water level of a well or river, and water enters the land through a conventional hose. Models of submersible pumps can push water up to 40 meters, and more complex ones up to 80.

Installation of such a system is not self-made and without the help of professionals it will be difficult to cope. Also, as with dismantling, you will need the help of a specialist. On the winter period the system must be removed if it is not to be used. There are two types of submersible water devices: vibration and centrifugal. The first is more accessible, but will not work in dirty water bodies (swamps). Centrifugal, on the other hand, carries out the flow of water thanks to the blades and wheels. Due to the strength of the action, dirty water is not a hindrance. Accordingly, the price of such a pump will be several times higher.

How they work

In order not to make a mistake in choosing a water machine, consider their classification according to the principle of operation.

The first type is vortex. This type of pump works only in pure sources. In the vortex water supply system, a lot of pressure is created, which is why a powerful pressure. The disadvantage of this type may not be high efficiency 45% and the presence of annoying noise.

The second type is centrifugal. They can be surface or submersible. Water is pumped by centrifugal force. They can serve for a long time, do not bring inconvenience and can pump water from reservoirs of any degree of pollution. Suitable for drip irrigation. Disadvantages: high price and difficult to install.

The third type of work is vibrational. The suction of water is carried out due to vibration. The principle of operation of this type of pump is similar to a submersible one, but there are nuances that must be taken into account. The vibration pump can quickly break down if the water in the well or any container is heavily contaminated. It is used in clean reservoirs, excluding the presence of silt.

Water pumps are also divided according to the method of supply. For example, a dependent power source is the best option for drip irrigation of a plot or garden. They work directly from the network. But autonomous or gasoline pumps work without a network, which simplifies garden work. But such power systems are much more expensive.

How to choose

First of all, you can consult with the seller in the store or a gardening consultant. Before you understand which pump to choose, you can and should analyze the source of water. For a well, pond or drip irrigation, you can use different types of surface devices.

But if you don't know how to determine suitable look pump, consider the following criteria:

• the state of the well fluid at the bottom of the well is the most important criterion;
• required temperature for different kind cultures. If the water comes from any container or drip irrigation system, make sure the water station is at the right temperature;
• system length. To do this, you can make special measurements. This is done so that the hose coming from the bottom of the well or with a drip irrigation system is of the right length and reaches the beds;
• the degree of pressure of the water supply system. It is taken into account both with a drip irrigation system and from a well;
• the size of the suburban area;
• the difference in height of the place where the pump is located relative to the site. So, with a drip irrigation system or from the bottom of a well, interruptions may occur.

When choosing the right system, consider all of the above factors. You can resort to the help of a professional, you can independently install a water pump. With such a variety of systems today, this is not a problem.

Any summer resident knows how difficult it is to take care of the garden in the hot and dry summer season. Plants require constant care and, most often, all work is done by hand. Anyone who has ever been engaged in gardening knows what running around with a watering can and daily watering planted garden crops is.
It is a little easier for the owners of such summer cottages, in which wiring from the central water supply leads to the house, however, such happiness is not given to everyone. Much more often, owners of suburban areas take water from wells or containers with rainwater accumulated in them, which does not water the plants on its own. She must be delivered to them.
Carrying heavy buckets of water is not only unpleasant, but also harmful to the spine. To solve the problem, use special equipment- pumps.

What factors should be considered when choosing the type of pumps

Currently, there are many different types of pumping equipment that can be used for irrigation on summer cottages. These pumps were created not specifically for use by summer residents, but they all work with liquids. Pumping equipment is selected depending on what liquid will be pumped by them and where it will need to be taken from.

Watering plants does not require perfectly clean and transparent water. They prefer watering with warm, if possible, settled water that does not contain harmful impurities and chemical production waste. Therefore, the ideal option is rain water, which is accumulated by thrifty owners in various containers placed in their summer cottages.

Quite often, water for irrigation is taken from wells or wells. However, such water has a rather cold temperature, therefore, with constant watering of plants with such water, many crops suffer from rotting of root systems. Cucumbers are the most susceptible to this problem.

To warm up well water, summer residents need to raise it up and let it stand for some time in a container. Only after the water warms up a little, you can scoop it up with buckets and water garden plants with it.

The same system for collecting water for irrigation is also used by the owners of summer cottages located close to natural reservoirs. Summer residents collect water in barrels, settle for at least a couple of hours, and then use it for irrigation.

The landscapes of some sites provide for the equipment of artificial reservoirs (ponds or home pools), the water from which can be used to water the garden. The water in such reservoirs is settled and warm enough. But, using these reservoirs for irrigation, it is impossible to use chemicals, because your vegetables will absorb them, which then you will have to eat with this chemistry. Watering the garden with water from the pools is doubly beneficial, because by regularly updating the liquid in the pool, you will not think about how to get rid of the old water.

Fluid in various sources It has varying degrees pollution, therefore, when choosing a garden pump for watering plants, it is necessary to take into account from which reservoir the water will be taken. For all sources developed different kinds pumps, which are as follows:

1. superficial
2. submersible
3. Drainage and other units

Main parameters and technical characteristics of pumping equipment

Choosing pump equipment for watering garden plants, take into account not only the types of pumps, but also their technical capabilities: indicators of power, performance and others. Therefore, you must first analyze the following parameters:

1. Calculate the distance in meters from extreme point garden to a source from which water for irrigation will be taken.
2. Calculate the height difference from the installation site of the pumping equipment to the extreme point of the site.
3. Determine how often you will need to water your garden beds.
4. Calculate the area occupied horticultural crops that need constant watering.
5. Choose the type of watering plants - under the roots, drip, sprinkler or other.

What factors determine the choice of pump types

It is better to use average indicators, so an approximate calculation of the characteristics of the pumps will look like this:

Taking into account the standards of SNiP, for irrigation of 1 sq. meters of beds per day, 3-6 liters of liquid are needed (the amount of water depends on the climate and soil condition in the region). If we assume that the garden has an area of ​​​​200 square meters. meters, then water is needed per day:

200 X 6 = 1200 liters.

Consequently, the pump needs to have time to pump this amount of water within an hour, since few people want to water for a longer time. Pumping equipment is sold with instructions that indicate the performance of the model. The same information is also indicated on the label located on the device. Productivity is denoted by the letter Q, and in our calculation it is approximately equal to 1.5-2 cubic meters. meters per hour.

Another equally important indicator is the height to which the pump is able to lift liquid from reservoirs. Otherwise, it can be called water pressure. The higher the height indicator, the greater the distance between the pumping equipment and the reservoir is permissible. For example, when maximum height model 40 meters, the water intake can be removed from the irrigation bed no more than 400 meters, since 10 meters horizontally corresponds to 1 meter vertically for a hose with a diameter of 1 inch.

The performance indicator of pumping equipment is lower if the distance or height from the reservoir is large - this increases the loss of fluid pressure.

For example, you need to water a plot using well water. Moreover, the well is located at a distance of 30 meters from the extreme point of the garden. The pump is lowered into the well to a depth of 6 meters.

1. It is necessary to calculate how long the pipeline is needed: 30 + 6 = 36 meters.
2. It is necessary to take into account the pressure losses inside the pipeline, as well as places where there are connections, turns and others. This will be approximately 20% of the length of the hose: 36 x 0.2 = approximately 7 meters.
3. This figure is added to the height of the water column, which in our example is 6 meters: it turns out 13 meters.
4. In order to exclude the operation of the pump with overloads, and to ensure the maximum allowable pressure at the outlet, you need to add another 10 meters.

The result is:
13 + 10 = 23 meters. It turned out the value of the pressure recommended for our example, denoted in the instructions by the letter H.

To summarize: in our case, it is necessary to use a pump whose H ranges from 25 to 30 meters.

The type of irrigation affects the motor power of the selected pump. Drip irrigation is carried out with low-power systems, and when sprinkling is used, systems that withstand high pressures are used.

Pumps for pumping liquid from a tank

The easiest care and connection is for the pump, which is used to pump water from barrels. it perfect option for use in the country:

1. Light weight (no more than 4 kg), allowing you to move the pump around the garden.
2. Working with containers less than 1.2 meters deep.
3. It is not noisy when working.
4. It is easy to fix it in the right place.

The pump is fixed on the barrel, then the plug is inserted into the socket and the irrigation process begins. The owner of the cottage himself sets the required water pressure using a pressure regulator. The pumps are equipped with built-in filters that keep out debris, so you can pour water diluted with fertilizer into the barrel and water garden crops with this solution.

In practice, the built-in filter does not always stop one hundred percent solid particles of fertilizers that do not have time to dissolve. Therefore, clogging of even the most expensive and high-quality systems is possible. Therefore, they are periodically cleaned.

This problem may not exist when installing a homemade additional filter, which is quite simple to make using old tulle. To do this, you need to find a piece of canvas that is larger than the volume of the barrel (the edges of the fabric should hang out). Then the pump is immersed in a tulle, the edges of which must be tied to the edge of the barrel. Don't be afraid to pull the tissue into the pump because the motor at the outlet protects the filter, which will prevent the system from being sucked in by the makeshift filter.

You can use another option: the pump is suspended from the board, which is placed on the container. It is not lowered to the very bottom of the barrel, but placed at a distance of 5 cm from the bottom. In this case, rust deposits will not enter the unit.

In retail chains, pumping equipment models with different power ratings are sold. If the garden is large area, it is better to purchase pumps equipped with two-stage mechanisms. They are more expensive, but they are capable of doing a large amount of work and will not overheat when used for a long time.

If your garden is small - just a few flower beds or beds, it is enough to use a low-power device. For example, well-known manufacturers Gardena and Karcher offer not very expensive models pumps with a price of 2.5 thousand rubles. They pump about 2 thousand liters of liquid for an hour, which is quite enough for a small garden.

If the site is large, you can look at the options more powerful. Barrel pumps from these manufacturers are produced with a maximum capacity of 4,000 liters per hour. If you are not satisfied with the cost of this equipment, consider the ZUBR brand - cheaper pumps that are produced by Belarusian manufacturers. They have floats in their kit, the characteristics are similar to Gardena equipment, but the cost is one and a half times lower. They have a 5 year warranty.

Basically, barrel pumps are sold without hoses, so it is better to purchase whole kits, which consist of:

1. Watering hose about 20 meters long
2. Two branch pipes
3. Outlet fitting
4. Spray nozzles

Cheaper options are sold without some spare parts, which will have to be purchased for a separate price.

When choosing a pump that has a float switch in the kit, you do not have to control the amount of water in the barrel. Pumping equipment is able to shut itself off at a minimum liquid level, which eliminates the risk of breakdown due to idling of the unit.

Surface pumps for pumping water from reservoirs or wells

If the liquid for watering the garden is taken from a well with a shallow shaft, or a reservoir (clean river, pool), it is advisable to use surface pumps that have a capacity designed to lift water from a shallow depth (not exceeding 10 meters). The pumps are called surface because they work on the surface of the reservoir. The unit is installed on the ground, only a hose is lowered into the water, which should not be rubber, because when air is pumped inside the hose, rarefied air collects, compressing the hose - water cannot pass through it.

To connect the pump, put it on a solid base and attach the hose. When operating, this pumping equipment makes a lot of noise, which can be reduced by putting the unit on rubber mat, or by hiding it in some room like a shed.

Surface pumps, which are used to pump water from reservoirs or wells, have the following advantage: when watering a garden, you do not have to move around often. A powerful jet of water helps to irrigate up to 50 meters at once, without moving.

Some summer residents have a question about whether it is possible to install equipment on the site itself, and stretch a long hose to the source of water intake. The weight of some systems is quite large, so not everyone can carry them. In addition, the unit installed near the reservoir can be stolen. But, alas, such an installation of the unit is impossible. The pump can be installed as far as possible from the water at a distance of 9 meters (this takes into account the distance the hose is immersed in water).

Pumps are divided into two types:

vortex pumps- which are used exclusively for clean liquids, therefore they cannot be used for pumping water from reservoirs. Them maximum efficiency equals 50%. But, having characteristics similar to centrifugal pumps, it is able to create pressure 5 times greater, which is very important for some types of irrigation (by sprinkling, for example).

Centrifugal pumps- they do not react very well to impurities, and when using an additional filter, you can pump water even from small streams.

An obvious plus surface pump its normal operation is considered with frequent starts - frequent shutdowns and shutdowns of the watering gun will not damage the motor.

Drainage pump pumping water from a polluted pond

If it is necessary to use water from swamps or ponds for irrigation, it is better to use a drainage pump, which is specially produced for pumping heavily polluted liquids with debris. The pump is equipped with filters and a chopper that grinds particulate matter. This is an ideal pump for irrigation from polluted reservoirs - it does not clog, but crushes garbage (silt, shells, etc.) and sends it to garden beds, fertilizing the soil.

Since such systems have low pressure, watering occurs by gravity. When connecting a nozzle (sprayer or gun), water will not flow. Drainage pumps best used for pumping dirty liquid into settling tanks. Then water the garden from the barrel using a surface or submersible pump, making sure that sediment does not get inside the unit.

When to use submersible pumps?

It is optimal to use a submersible pump in areas with punched wells or wells. The pump must be completely immersed in water, so a specific model is selected depending on the height to which the unit raises the water column.

The use of low-power submersible pumps is carried out in wells with sufficient depth. by the most simple models are vibration pumps"Brook", "Spring" and others. They well raise liquid from shallow wells or close reservoirs, and sink to a depth of no more than three meters.

In addition, they are immersed to a depth of at least half a meter, so these units do not work in shallow water. With a maximum water lift of 50 meters and an immersion depth of 3 meters, a hose no longer than 450 meters is required. If the river is located at a great distance from the suburban area, the use of a vibration pump is not possible.

The maximum liquid lift is indicated on the unit label. It is denoted by the letter H and is measured in meters.

If the average capacity is 20 liters of liquid per minute, the pump pumps out 2 thousand liters within an hour and a half, and when pressure losses are taken into account (where the hoses connect), this figure decreases even more. In addition, it is necessary to take into account all adapters when connecting hoses. Adapters affect the pressure drop and reduce the speed of water movement.

Therefore, if you decide to water the plants in your garden at the root, the Brook pump model will suit you. But when using sprinklers, vibration pumps cannot be used because of their sensitivity to pressure changes - the slightest overload will lead to motor failure.

Pumps with an upper water intake are practical, since this reduces the likelihood of silting - sand particles and bottom sediment do not enter the system.

Some practical summer residents have enough "Brooks" when watering from barrels. Having pumped water into the barrel, they wait until it heats up, and then all that remains is to immerse the unit in the barrel and use it for irrigation. True, such pumps are very noisy.

With a distance to the reservoir exceeding 200 meters, the most reliable use of submersible centrifugal pumps with a minimum water pressure of 70 meters. To organize the supply of water to the garden, it is necessary to lay up to the pipe section PND32 or 40, since unwinding the hose over such distances is not a convenient task. When using a hose, it is advisable to purchase three-layer PVC 3/4″, which has additional reinforcement. A simple hose can stick together due to the pressure difference, disrupting the system.

The watering hose must be dense, multi-layered and reinforced.

A downhole (deep) pump is difficult to install and maintain, so only a professional can work with it. In addition, such pumps are dismantled for the winter period. But if there is no way out, then liquid is pumped into the tank with such a unit, and when it heats up, a less powerful and complex pump is used - a surface or barrel pump.

The use of drip irrigation using special equipment

Gardeners who are accustomed to saving water use drip irrigation to water plants, which can save time and not waste water. With drip irrigation, you need to use special submersible pumps equipped with automation. The summer resident needs to set the required mode on the pressure switch and use the timer to set the watering time. The rest of the actions are performed by the system itself.

This is expensive equipment that helps the owner save time.

If it is impossible to purchase a pump with automation, buy submersible unit and buy the necessary parts.

However, the creation of the necessary working pressure (1-2 bar) is within the power of any inexpensive pump. But, it is impossible to get water from a reservoir without equipping pumps with additional filters, since the unit will constantly clog. Therefore, it is better to take water from the central water supply, a well or a well.

As you understand, the most reliable type for drip irrigation is centrifugal pump. They are supplied with a lot of liquid during the day under high pressure, and at the same time the motor does not overheat.

To select a pump that has optimal performance, you need to know the rate of hourly water consumption. To do this, you need to draw the location of drip tapes on a piece of paper and calculate the length of the water supply. Multiply the resulting figure with the number of droppers that occupy one running meter. Get the performance of the pump.

When choosing a pump, do not try to find famous brand. Better get acquainted with its characteristics, power, operating conditions and the level of popularity in your region. Knowing the popularity is essential, because if the pump breaks down, finding replacement parts will be much easier.

When growing vegetables, always important role playing pumps for watering the garden. You can buy a plot with fertile soil, excellent seeds, grow good seedlings, but with the advent of drought, the flowering soil turns into a desert. Only a well-mounted water supply system will save the crop, saving the owner from manually irrigating the beds.

Irrigation pumps for the garden, what are they?

Irrigation equipment garden plot now it’s easy to find, there are many different pumps that differ in design parameters or in power. The choice of the optimal apparatus depends on several indicators - the type of water source, the degree of contamination of the liquid used, the depth of the well, the distance from the well to the garden, and the duration of work. An improperly selected water pump when watering the garden will quickly fail or will not create the required pressure.

How to choose pumps for watering the garden:

1. The first main parameter for a pump of any type is the performance (Q) of the purchased apparatus. We take the area of ​​\u200b\u200bthe garden and multiply it by the required amount of water for 1 m 2, getting the total amount of water for our garden for a day. For example, there is a plot of 100 m 2, we want to pour up to 5 liters per 1 m 2, having completed all the work in an hour. By simple calculations, we obtain the desired performance of the pump for watering the garden: 100x5= 500 l / h.
2. The next important parameter is pressure. For example, the depth of the well is 10 m at a distance from the bed of 50 m. The total length of the main line is 60 m, multiply the figure by 0.2 and get a discount on losses of 12 m. We summarize the result with the depth of the well: 12 + 10 \u003d 22 m. Add 10 m to ensure that garden water pumps supply water without overloading. The optimal pressure for our example is: 10 + 22 = 32 m. We choose a device that has a passport indicator slightly higher than the calculated one. It should be borne in mind that horizontally pumps are capable of supplying water 10 times farther than from the depth of the well.

The choice of a pump for a dacha and a garden does not always depend on our desire, it is often necessary to use stationary deep equipment instead of compact portable pumps. Submersible pumps for watering the garden are vibration, centrifugal and screw deep devices operating under water. You can classify them with a completely waterproof case. Often they are installed directly in the well for the whole season; for the winter, when the water supply is turned off, the system is dismantled.

Common in everyday life, they supply water with the help of a lifting force created by rotating the blades. They are surface and borehole, horizontal and vertical type. Multi-stage models are more powerful and create more pressure. Centrifugal apparatuses are more complicated and more expensive than competitors, they work perfectly in clean water from a well, but they do not tolerate liquid with particles of impurities. The most durable devices are made of cast iron or stainless steel.

Screw pumps for the garden and cottages are devices that are designed to work in wells. They do not supply water with impellers, but with the help of a screw mechanism. These devices are cheaper than vane pumps, have simple design able to work with muddy water with minor impurities. Augers can generate good pressure at lower rates and are therefore suitable for low flow wells.

Units of this type are famous for their simplicity of design, compact size and the most affordable prices. With small sizes, vibratory irrigation pumps for the garden give out a good pressure of water, performing all the tasks set by the consumer. With all the undoubted advantages, this equipment has some serious drawbacks:

• vibration pumps make a lot of noise,
• they don't have their own filters,
• vibration often leads to spontaneous untwisting of the tie bolts,
• these devices are not suitable in terms of power for sources with great depth,
• vibration contributes to the gradual siltation of springs dug in sandy soil.

Apart from electrical devices in suburban areas, they often use a gasoline pump to water the garden from the river or diesel-driven devices. This type of equipment is suitable for summer residents whose well or well is located far from the source of electricity. Diesel pumps are more powerful and burn less money for fuel, but their competitors have important advantages. The gasoline pump will always be more compact, lighter, cheaper to repair and purchase.

Which pump is best for watering the garden?

When caring for plants, it is better to use water from a river, a pond, a reservoir filled in advance. A liquid that has a temperature much lower environment, provokes the development of infections and the death of peripheral roots. Before buying equipment, it is advisable to understand well the question of which pump to choose for watering the garden. Work with barrels, tanks, natural and artificial reservoirs, a deep well, differs in some nuances.

When servicing a large capacity, there may be different variants. If you have a source of water nearby, then fill the barrels first from the well with any deep submersible pump, we give time for the liquid to settle and warm up in the sun. Next, we use it by pumping water out of the barrel through a hose or using a special water supply system. In the case when the well is located far from the garden, the barrel will have to be filled using a mobile tank using vehicle at an intermediate stage.

It is easy to pump water from a nearby pond or river with portable surface pumps by throwing a suction hose into a pond. The purity of the liquid plays an important role. At in large numbers impurities cannot be dispensed with without a filter, otherwise pieces of dirt can clog the pipeline or internal parts of the equipment. In the question of how to choose a pump for watering the garden, cottage owners often prefer drainage devices. They are able to work with coarse fractions in shallow silty water bodies, well withstanding heavy loads in extreme conditions.

Pumps for watering the garden from the well

Well pumps for watering the garden are selected taking into account the depth of the well. With a suction height of up to 10 m, it is allowed to install a surface pump or an automated pumping station installed inside the equipped pit. If a ground water located at a greater depth, then you cannot do without special submersible-type equipment. Inexpensive devices work up to 40 m, the most powerful household pumps can lift water from 300 m depth. It is desirable to locate them no closer than 1 m from the bottom, so that sand and clay are not captured during suction.
