The pump for watering from a well is superficial. Pump for increasing water pressure for watering the garden in the country. Types of pumps for pumping water

Timely watering is the key to the excellent condition of plants and a rich harvest. Summer residents strive to please their beds with the necessary moisture, even to the detriment of their health. Buying a good and reliable pump would solve the problem of watering the garden forever. But deciding to purchase it, it is worth considering the pros and cons of each of existing species these units. This article talks about two types of pumping devices: drainage and barrel, discusses their strengths and weaknesses.

These devices can be used to pump water from any source, at different temperatures and liquid conditions. Such a pump is not afraid of pollution and solid inclusions due to the built-in grinder, which easily turns them into powder. Therefore, water, falling on the beds, not only moisturizes them, but fertilizes them with useful microelements obtained as a result of grinding various inclusions. There are three types of drainage pumping devices on sale: semi-submersible, surface and submersible. All of them are similar in their structure.

Peculiarities

Surface models can be: centrifugal type, vortex and liquid-annular. For domestic use, the first type is used. They are equipped with blades that have complex shape. Due generated pressure the liquid, as it were, rolls between them and enters the pipeline for removal. This design is easy to operate and reliable.

The submersible drainage pump consists of an open wheel with blades made on it. Its device allows to reduce the hit particulate matter to the units of the unit. Therefore, such devices are guaranteed to work for more than 10 years, and due to their small dimensions they are very mobile.

On the video - a drainage pump for watering the garden (how to choose):

Any model of drainage pumps has individual distinctive properties and characteristics, but their internal structure is almost the same. Water enters the pump through special bottom holes in the housing. Each one is protected. strainer. The latter protect its impeller from large particles and contaminants. The mesh size of these filter devices is indicative. They determine the maximum possible size particles that the machine can pump along with water.

Almost all devices are equipped with automation. The pump starts and stops automatically, special protective systems block the pump at idle and thus save it from overheating.

The drainage pump can eventually be equipped with a gasoline generator, which will make it completely mobile. It will eliminate the use of stationary energy sources, and the device can be used in any part of the yard.

Operating data

Submersible-type drainage pumps are hung by the handle, and surface pumps are installed right next to the water source on flat surface. If you plan to use the latter type for a long time, then it is worth providing for it a shelter or at least a hinged roof. Which will play the role of protection and protect the device from the effects of precipitation. It is impossible to install surface-type units simply on the ground, it can jam the working impeller, so a stand is needed.

The pump will last longer if several parameters are observed:

• the content of contaminants in the liquid should not exceed 10%;
• maximum parameters of solid particles - 5 mm;
• there must be a stable mains voltage of 220 V;
• operate at a frequency of 50 Hz.

The pump body is made from polymer materials reinforced with fiberglass, of stainless steel or cast iron. Therefore, they are quite durable.

Advantages and disadvantages

It should be noted right away that the advantages of these devices far exceed their disadvantages. So let's start by listing the positives:

• able to work with water of varying degrees of pollution (they can pump water even from a swamp);
• differ in safety. On many models, a special automatic switch is installed. It slows down the operation of the device in the absence required level liquids. The devices are grounded;
• high performance. Cheap and low power models able to pump 8 cubic meters of moisture per hour and at the same time withstand a pressure of 7 meters;
• reliable. The body is made of high-strength materials and therefore provides a high degree protection and prevents water from entering the device;
• overheating is excluded in submersible models, because they are completely in the liquid and it removes all the heat when it exits, and the surface models have thermal protection;
• quiet operation of submersible units;
• in winter time devices do not freeze during operation;
• mobility and functionality of devices;
• economical. Even with high power electricity consumption is low;
• durability;
• affordable price;
• are easy to install and dismantle.

The disadvantages include:

Drainage solve any problems associated with the supply of water to personal plot. It is only necessary to choose the right model, while taking into account the working conditions pumping device, type of water source, the required amount of moisture for daily consumption and the state of the liquid. Purchase drainage pump justifies itself from the first days of use.

For those who do not have a single source of moisture on their site, you need to look for alternative solutions to provide plants with fluid. One of which are tanks for collecting water during precipitation. This is the simplest and economical way garden moisture.

Watering from a barrel

Many crops require watering only warm water, and in an open reservoir, and even more so in a well, it does not warm up to the required temperature. Special containers must be used. For the most part, barrels are used in summer cottages. Of these, they carry water in buckets and water whimsical plants. To eliminate this hard work, pump manufacturers have invented special models for pumping fluid from any reservoir.

They are called barrel pumps. Among all similar devices, it is distinguished by its low weight - about 4 kg and the ability to work with containers whose depth does not exceed 1 meter and 20 cm. They are easily attached to the walls of barrels and operate silently. Their installation is quite simple: the unit is fixed on the wall of the tank and plugged into a power outlet. After these steps, you can water. The device is equipped with a built-in pressure regulator, with the help of which you can choose the necessary pressure yourself.

Important! For those who have a large enough irrigation area in the country, a two-stage barrel pump should be chosen. They are distinguished by reliability, durability and high performance than its counterparts.

Filter protection

Each model is equipped with a filter that protects the device from suction of large particles. But they become clogged over time and therefore the pump must be periodically cleaned of various insoluble contaminants. To do this less often, you can buy an additional filter device or make it yourself. To do this, you need an old tulle whose size should be enough to fix it on the surface of the barrel. The edges homemade filter are fixed on top of the tank, and the pump is placed in it. The stationary filter will prevent the tulle from getting inside the apparatus.

The video tells whether it is possible to use a drainage pump for irrigation:

There is one more homemade version- preliminarily fix the pump on a board that is laid on the tank. The device in this case will not reach the bottom and bottom sediments will not get into its device.

The complete set of the barrel pump consists of a 20-meter watering hose, an outlet fitting, two nozzles and a spray nozzle. Cheap models may not have several elements, so they should be purchased immediately in one store.

Advantages

• simply attached to the walls of storage tanks;
• has a high pressure at relatively low power;
• mobility. Its light weight and size makes it easy to transport. Such a device can be located on any container on the site, even on a bucket;
• machine automation. Some irrigation settings can be set independently;
• low cost;
• they can pump water directly with fertilizers;
• does not make noise during operation.

A barrel drainage pump is an indispensable tool for a summer resident for watering a garden. It is reliable and durable, does not require a well or reservoir on the site, and can pump water from any container. When choosing it, you should focus on performance, power and equipment. By choosing suitable model, you will become the owner of an invaluable assistant in the household.

To grow a crop, it is necessary for plants to provide proper nutrition, loose soil and watering. Work in the garden is time-consuming and can create conditions for diseases of the spine. To avoid this, it is necessary to organize working space thinking through every detail. The issues of delivering water to plants will help to solve water pumps for watering the garden.

Manufacturers produce water pumps with different functions and features. To select the necessary technical specifications, pay attention to:

• on the performance of the unit
• the amount of water pressure,
• how often do you need to water,
• serviced area,
• how far is the source of water from the irrigation site,
• The decisive factor when choosing an irrigation system is the conditions of the site where the irrigation will be in terms of: what sources are available, where you can draw water.

On the garden plot or in a private house there may be a variety of possibilities for the use of water.

• In rare cases, especially in countryside there is a water supply system, and this water is used for irrigation.
• The site may have a natural or artificial reservoir. It is also possible to find a river or a pond in the immediate vicinity of the garden.
• Often the watering issue is resolved by a well or well.

Before choosing a pump for irrigation, you need to keep in mind that different water sources determine the irrigation system in a particular area. Here one more factor connects its influence: what kind of water is suitable for irrigation. Plants do not respond well to cold water containing all sorts of impurities. Well perceive watering from a river or pond. But water from a well, well or water supply must first be collected in containers.

It is advised to hold such water in the sun so that it warms up and is enriched with active substances. With salts, which are often present in tap water, also fight by defending it in containers.

• When using barrels and other tanks for settling and warming water, a barrel pump is used to water the garden.
• If water needs to be obtained from a well, then use submersible pumps.
• Obtaining water for irrigation from shallow wells and reservoirs is done using surface pumps.
• If water must be taken from a polluted reservoir or swamp, then it is used.

Irrigation systems also differ in the degree of automation. Watering with the help of pumping units can be:

• Semi-automatic mode - the owner turns the system on and off at his own discretion, makes adjustments during operation.
• Automatic mode - connected to the system automatic control with timers. It is necessary to make a setting at startup, at what power and for how long the system should work.

– the most necessary hydraulic device in a suburban summer cottage, where there is no water supply from the central water supply channel. If automated watering of beds and flower beds is also relevant for you, below you will learn all about how to choose pumps for watering a vegetable garden from a barrel.

Description of the pump for irrigation and its varieties

The main feature of barrel pumps for watering a garden from a barrel is that they are able to independently create pressure and pump water out of the barrel, supplying it through a hose to the right place. Perhaps this is due to the fact that during the start-up of such a unit, a vacuum is created inside it, into which water is drawn. Since the vacuum is created continuously, more and more portions of water are pumped into the sediment, and those that initially got into it under pressure are thrown out.

There are special pumps designed specifically for working with barrels. They are distinguished by their very compact dimensions, as well as the presence of a water supply hose (in some versions even with a convenient sprayer and flow regulator) and a water pressure regulator. Filters are also installed on many pumps of this type, so clean water must be selected for them. During operation, such a pump simply clings to the edge of the barrel and starts either from an outlet or from a battery. In addition to compactness and ease of installation, such devices allow you to add fertilizers to water during irrigation. The most common barrel pumps are units manufactured by the German company Kärcher.

However, to organize the watering of the garden from the barrel, you can use not only special barrel devices, but also other types of pumps that are likely to be in your pantry.

Did you know? The big advantage of barrel irrigation is economy, as pumps suitable for this type of irrigation are very affordable. Their cost ranges from 400 to 1500 thousand UAH, and the service life is not limited.

Submersible

A submersible pump for a barrel for watering beds is different in that it descends directly into a container of water, which it will subsequently pump out. Such pumps are designed to supply water from wells and wells, so they often have very high power. When choosing a submersible pump in a barrel for irrigation, it is better to stop at the simplest and weakest option, since it is unlikely that you will find a barrel with a capacity of more than 500 liters on your site.

When buying such a pump, it is worth remembering about its following features:

1. Unlike a barrel pump, a submersible pump can be used not only in a barrel.
2. A submersible pump is capable of lifting water from any depth to which it itself will be lowered.
3. In winter, the operation of submersible pumps in a barrel is not possible, although they can be operated in a non-freezing well even in severe frosts.
4. It is the most silent device for watering, as it works under water.

Drainage

A drainage pump for watering from a barrel and generally watering beds is practically not used, since its main purpose is to pump liquid from flooded rooms or feces from a toilet. However, if you already have such a pump on the farm, it can be easily adjusted to the needs of the garden. For irrigation, you can use the smallest drainage pump in terms of power. At the same time, he will be able to supply water not only from a barrel, but even from a pond, if there is one on your site.

Surface

Surface garden pump for watering from a barrel has the following principle of operation: the device itself is installed on a solid surface, and the water intake hose from it is thrown into the barrel. On the other hand, the pump is connected main pipe, into which water will be supplied from the barrel, and from which you will be able to irrigate.

Important! If you decide to use a surface pump to supply water from a well, please note that it is not capable of lifting liquid from a depth of more than 9 meters. However, in the case of barrels, it will work perfectly.

Benefits of Using a Barrel Pump

To water the garden in the area where, apart from the old well or pond, there are no more water sources, summer residents have to rush all evening or all morning with heavy buckets and watering cans. But if the garden is really large, you should think about facilitating the task of watering, with which a conventional water pump for a barrel will help to cope.

The benefits of using it include:

• significant reduction in irrigation time;
• the possibility of supplying rainwater collected in barrels from sewers to the garden;
• the ability to irrigate when the pressure drops in the central water utility;
• the ability to transfer and reconnect the irrigation device, each time taking water from barrels installed in different parts of the site;
• the ability to add to water for irrigation mineral fertilizers and simultaneously with watering, feed the plants in the garden.

Did you know? Depending on the method of pumping water by the pump itself, these devices are divided into centrifugal, vortex and vibration. For watering the garden, it is better to opt for vibration ones, as they are able to pump even polluted water and will not fail even if air enters.

Features of irrigation pumps: how to choose the best option

Find the best pump for your suburban area not so simple, since in each case there will be a need for devices of different power and performance.

It is equally important to initially decide on the following questions:

1. Will the pump be used only to pump water from a barrel, or is it necessary to use it to pump water from a basement or pump water from a well?
2. At what distance is the garden and flower beds from the barrel (taking into account this distance, not only the pump power will be selected, but also the length of the hoses for supplying water)?
3. Are there elevation differences on the site, what is their direction and magnitude?
4. How often and how long will the pump be used?
5. How much big square vegetable garden (how much moisture will have to be pumped into it daily)?
6. What type of watering do plants need - drip, rain or under the root?

Based on all these indicators, let's start calculating the required pump performance, which is how many liters of water the pump can pump in 1 minute. It is clear that when it comes to watering garden plants, too much water may damage them. Therefore, the pump capacity for a 200 liter barrel for irrigation should be about 5-10 liters per minute. Given the fact that average requirement garden plants in water is 5 liters per 1 sq. m, in 1 minute you can water about 2 sq. m of your garden, introducing moisture as accurately as possible.

Important! If the garden area is very large - about 300 square meters. m, then the pump must be selected with a high capacity, otherwise you will spend a lot of time on watering. To water such an area in 30-50 minutes, you will need a pump with a capacity of 30-50 l / min.

But the feed rate also depends on the pressure that the pump can provide, and on the height from which the unit has to raise water, and the height to which water must be pumped. It should also be understood that if the difference between the height of the water intake and the height of the drain is large, the pressure will be small.
To select a pump with the right kit, it is important to make some calculations. Let's say your barrel of water is dug in to a depth of 1.5 meters, and the garden bed that needs watering has a length of 35 m (35x0.1 = 3.5). Immediately calculate the 20% head loss due to joints and turns. Next, we summarize the height of the water rise, the length of the beds and the number of head loss: 1,5+3,5+7=12. It is recommended to add a margin of 10-15 units to the obtained pressure value, which as a result will require the purchase of a pump with a pressure value of 25-30 units (this indicator will be indicated in technical passport to the pump with the letter "H").

As for the power of the pump, it will directly depend on the type of watering that is required specifically for your garden. Pump power for drip irrigation from a barrel may be minimal. If you have a need for abundant watering garden trees, then it is necessary to take a pump that can withstand a large pressure.

How to organize barrel watering

Each watering pump has its own characteristics of functioning, which are important to know about when connecting each of them to a barrel of water. Below we consider this issue in more detail.

A submersible pump for supplying water from a tank is quite difficult to connect, so it often requires the help of a professional to install it. It should be understood that the device will function in water, so even one incorrectly tightened nut can cause damage to the pump or slow corrosion of its individual parts.

When organizing irrigation with a submersible pump, you will also not be able to often transfer the unit, so only one barrel can be used for irrigation. Another feature is that the pump will not be able to pump absolutely all the water out of the barrel, so there will always be residues at the bottom that can become moldy over time. In this regard, the barrel will have to be periodically washed out very carefully. Another disadvantage of using submersible pumps is the impossibility of dissolving fertilizers in water for irrigation, since they can damage the unit itself.

How to organize watering with a drainage pump

The drainage pump for the barrel is best connected to a container dug into the ground, which will reduce pressure losses when pumping water to the garden. This type of pump is best suited for watering the garden, since with a small pressure they are able to simultaneously pump out very a large number of water. With such watering, the outlet hose can simply be thrown into the aisles of trees or in the middle of two beds and follow the unhurried pumping of water.

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.
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 in suburban areas. These pumps were created not specifically for use by summer residents, but they all work with liquids. Pump 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, rainwater, which is accumulated by thrifty owners in various containers located in their summer cottages, can be considered an ideal option.

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.

Landscapes of some sites provide for equipment 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

When choosing pumping equipment for watering garden plants, they 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. This is 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 don't offer much 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 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 advantage of a surface pump is its normal operation 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 grinder, which grinds solid particles. This is an ideal pump for watering 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 are best used to pump 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 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 a submersible unit and purchase 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 a 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.

If country estates have a personal plot, then, most likely, it is used either for agricultural or for decorative and floricultural purposes. And in fact, and in another case, you can not do without the regular conduct of certain agrotechnical work. And irrigation will always be in the foreground - without effective irrigation, especially in dry summers, to achieve high yield, beautiful flowering flower beds or even just a juicy green lawn - it is hardly possible.

Even in the case when a water main is connected to the site, using water from it for irrigation is by no means The best decision. Firstly, it is very wasteful, and secondly, such water undergoes certain processing, including chlorination, and is not very useful for plants. For irrigation, it is better to use some natural source, but to use it you will need special equipment - a pump.

However, if the buyer goes to the store or enters the online catalog unprepared, he may encounter a lot of questions that will make optimal choice extremely complex. Pumping equipment is very "many-sided" and differs not only in technical specifications but also in terms of performance. It is necessary to take into account many criteria in advance in order to leave your choice on the model that is most suitable for the existing conditions. This publication is dedicated to this - we buy a pump for watering the garden: varieties, selection, installation, basic operating rules.

Where will the water come from?

It is impossible to choose the right pump if you do not decide in advance where the water will be taken from for irrigation. There may be many options here.

• The most successful "layout" is when the site has its own or a reservoir located in the immediate vicinity natural origin- a pond or lake fed from underground sources or a stream and having a sufficient debit of water. It is possible to carry out watering from the river flowing nearby. In any of these cases, a surface pump or a submersible (semi-submersible) drainage type may be required.

If the site has an artificial reservoir - a pond or pool, then it can also become a source of water for irrigation. All the same, the water in it should change regularly, and these two operations can be combined - supply fresh water to the pool, pumping it out to the garden that already needs to be replaced. True, on one condition - that no chemical reagents were used.

• Even a somewhat swampy reservoir can serve as a source of water for irrigating the site, but in this case you will have to purchase a special kind of drainage pump, which is designed to pump dirty water.

However, such ideal conditions are quite rare. Most often, one has to resort to artificially created water sources.

• For irrigation, you can use water from a well or well. For wells, both surface pumps (with a shallow aquifer) and submersible pumps can be used. For wells where water is usually found at great depths, only submersible pumps of a special type are suitable.

Water intake from wells requires special pumping equipment

To raise water from a great depth and at the same time provide it with sufficient pressure and the required flow rate for further use - not any equipment can handle this. How to approach - read in a separate publication of our portal.

However, you should immediately important note. Any experienced gardener or the gardener will say that it is highly undesirable to use water directly from their well or well for irrigation, since such irrigation of plants can do them more harm than good. The best option- the required volume for regular watering is pumped in advance into containers installed on the plot. The water will warm up in a day, get rid of the substances dissolved in it. chemical compounds, and will become quite suitable for irrigation. By the way, this approach opens wide opportunities competent use of fertilizers and top dressings with exact observance of the recommended proportions of dilution of the compositions.

For a set of containers, the already mentioned well or borehole pumps. But directly for irrigation, it will be possible to acquire a compact surface-type garden pump or special submersible models designed specifically for taking water from containers (barrels, eurocubes, home-made tanks, etc.).

• A good owner should not lose anything, including rainwater, the collection of which in garden containers is very often organized from drainage systems. And besides, if a competent storm sewer, then a storage storm collector can also become a source of water for irrigation. In this case, the submersible drainage pump will again become an assistant.

How is storm sewer arranged?

Unfortunately, about this system, water drainage from adjoining territory not everyone remembers, or they ignore its creation in the hope that everything will somehow “dissolve” by itself. Why this approach is wrong, and how to create it correctly - read in a separate article on our portal.

So, the choice of a pump for irrigation in the first place will depend on the type of water source used.

What performance and pressure ratings are required?

Whatever type of pump is chosen, this unit must fully cope with the functions assigned to it.

1. Firstly, it must ensure the pumping of the required volume of water at a certain time - this is an indicator of performance.

It is not difficult to calculate this parameter. Based on the fact that existing rules for quality irrigation square meter area requires 3 to 6 liters of water (depending on local conditions climate, features of cultivated crops, established weather). It is best to calculate to the maximum - this will create a certain reserve of productivity, but everyone is free to decide this issue on their own.

Of course, only the area of ​​\u200b\u200bthe site that is allocated for crops that require regular watering is taken into account. If a lawn is cultivated or flower beds, their area is also taken into account.

The next value required for the calculation is the time that is planned to be spent on watering the entire area. Usually this event is held in the evening, after the subsidence of the heat of the day and the aggressiveness of direct sun rays so maybe an hour or two will suffice.

To find the required productivity (usually it is indicated in the technical documentation by the symbol Q), it remains to multiply the area of ​​​​the irrigated area and its irrigation rate, and divide the resulting value by the time allocated for irrigation.

Q=S uch ×N/t

S uch – irrigated area (m²).

N- the accepted watering rate is from 3 to 6 l / m² (for individual crops it may be more).

t- the time allotted for watering the site.

For ease of calculation, you can use the proposed calculator. The area in it is indicated in acres - so many gardeners are more familiar.
