In order for the country beds to justify the suffering of their owners, who spend the whole summer in care of the future harvest, it is necessary to establish stable watering. True, in rainy years the weather helps gardeners in many ways, but in the heat you have to run around with watering cans and buckets in the morning or in the evening to water the plantings. And all because suburban areas are still deprived of a central water supply system, and you have to get out on your own. But still, there is a way to facilitate watering, ridding the owners of heavy buckets, which later backfire with pain in the spine. You just need to go to the store where pumps for watering the garden are sold and find a suitable system.

Where will we get the water from?

The first step is to decide where you get your water from. From the point of view of plants, the water should be settled and warm. Cleanliness does not play a special role. The main thing is that there are no chemicals or other poison. The best source is, of course, rainwater, which the owners collect in barrels, basins and other utensils, placing it under the gutters. If a well is dug at the dacha or a well is drilled, then water is taken from there. True, garden plants do not really like a cold shower, which causes rotting of the roots, but you can first fill the containers with water, and after it warms up under the sun, start watering.

Another good source is a home pond, pool, or body of water. In each of them, the water must be periodically renewed, so that summer residents get a double benefit: they will water the garden and clean the water structure. True, swimming pools are useful only if you do not use chemical agents for cleaning and disinfecting them. Some summer residents who are lucky enough to have a plot near a natural reservoir (rivers, lakes) carry water from there. Based on which of the above sources supplies you with water, they choose pumps for irrigating summer cottages.

We select the pump to the water source

For gardening purposes, four types of water pumps can be used: barrel, surface, submersible and drainage.

Watering from containers: barrel pump

The barrel version is considered easy to install and convenient to use. It was created specifically for pumping water from storage tanks, such as barrels, eurocubes, etc.

The barrel pump can pump water from containers up to 1.2 m deep

The weight of such systems is no more than 4 kg, so you can walk with it throughout the entire site, placing it one by one on containers that are placed to collect precipitation. Most often, the pump for irrigation from a barrel is designed for a tank up to 1.2 m deep. It is fixed on the edge of the tank, plugged into the electrical network and watering begins. The pump has a pressure regulator with which you can set a higher or lower head, a filter that retains debris and a hose.

Low noise level is considered a big plus of drum pumps. When choosing this model, you need to pay attention to how much capacity it is designed for, how much water it can pump per hour. The most reliable are considered to be pumps with two-stage mechanisms. They both have higher productivity and a longer service life. So summer residents, who have a large area for a garden and a flower garden, should pay attention to powerful systems.

Some special rules must be taken into account when selecting pumps for pumping and pumping water: https://diz-cafe.com/tech/dachnyj-nasos-dlya-otkachki-vody.html

Lightweight barrel pump can be carried anywhere on site

Drum pumps are also convenient because the water can be diluted with all kinds of fertilizers and water the garden with ready-made solutions.

Surface pumps: friendly with ponds and shallow wells

If the main source of water is a natural or artificial reservoir, as well as a pond, pool or shallow well, then a surface pump should be purchased. It is designed to pump water from depths of up to 10 meters.

Surface pumps are placed on rubberized mats to reduce vibration

Such a unit is installed, as a rule, on the ground, and the injection is carried out using a special water intake hose, which is lowered into the source. On the other side, a metal pipe is connected. It is not recommended to use rubber hoses to bring liquid to the surface, because the unit pumps water by suction. This can create rarefied air inside the hose. As a result, the walls will shrink and prevent the water flow from moving upward normally. Such systems are popular for their ease of installation: you just need to place the unit on a flat, dry surface and connect the hoses. Interestingly, such pumps can deliver a powerful stream to a level of 30-50 meters, so that most of the beds can be watered from one place.

A spoon of tar! Surface units are very noisy, so they are hidden in the outbuilding in order to somehow get rid of the growl. You can also reduce the noise level by placing the system on a vibration-dampening rubber mat.

Submersible pump: able to get water from a well

Submersible pumps for gardening purposes are rarely used, but if a well is drilled in the country or in a well the water level is below 10 meters, then you cannot do without them. They are lowered below the water level into the source, and the liquid enters the surface through ordinary hoses. An important indicator of submersible systems is the height to which they are able to raise the water flow. If the well is shallow, then a simple model, designed for 40 meters in height, will perfectly cope with fluid lifting. For great depths, you need to look for models that are capable of pushing the jet 80 meters.

Submersible pumps are difficult to install, therefore they are rarely used for irrigation.

The disadvantages include the complexity of installation and maintenance, which should only be carried out by professionals, as well as the need to clean up for the winter if the system is not used during this period. Dismantling also requires the invitation of specialists. Submersible pumps are available in two versions: vibratory and centrifugal. Vibratory ones have a lower price, but they are afraid of getting into the sludge. Centrifugal pumps raise water due to the work of blades and wheels with such force that dirty water does not scare them. But their cost is several times higher.

It is possible that you may need a motor pump. When is it worth choosing it: https://diz-cafe.com/tech/motopompa-dlya-poliva-ogoroda.html

Dirty pond or swamp: the drainage pump rushes to the rescue

Drainage pumps are produced for other purposes: they pump out flooded rooms and cesspools. So they are not afraid of any debris and particulate matter. For irrigation of beds, a system with a grinder for pumping out cold effluents is quite suitable. If silt, leaves and other debris get inside, the chopper will chop them into small pieces and give them along with the water to the garden. For very dirty natural reservoirs, this is the best option, because other models will be clogged with large solid particles. By the way, grinding silt and small inhabitants of the reservoir, such a pump will provide the earth with additional natural fertilizer.

Drainage pumps are suitable for summer residents who use water from reservoirs

Automatic irrigation pumps with timers

For owners who do not have time to water for many hours, it makes sense to purchase a drip irrigation pump. Such systems are equipped with a pressure switch, a pressure gauge and a hydraulic accumulator. These mechanisms work automatically in a human-defined manner. For drip irrigation, you need to set the minimum pressure level, and then the water will flow in a slow trickle. In such systems, there is both manual and automatic control, carried out by a timer.

The automatic system allows you to set the mode required for drip irrigation

When choosing a specific pump option, pay attention to what kind of water it is designed for. So, irrigation units can only be used for wells, wells and tanks, because any small debris will clog the system and quickly disable it. Other sources (reservoirs, pools, ponds, etc.) require a drainage or even a fecal pump, depending on the degree of water pollution.

How to find a good pump for watering your garden with water from a pond, barrel or reservoir

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

To water the garden, you need to correctly select the pump


Types of pumps for pumping water

Two types of pumps are used to irrigate garden crops. Depending on the method of water intake and the location of the unit body relative to the source, they are surface and submersible.

Option # 1 - barrel for pumping out tanks

Such devices are designed specifically for pumping water from small tanks, the depth of which does not exceed 1.2 m.

Among the pumping equipment on the market, such units are considered the easiest to use and maintain.

The main advantage of pumps for irrigation from a barrel is compactness and mobility. The average weight of the unit is 3-4 kg.

Taking it by the handle, it is convenient to carry it around the site and alternately install it on the containers placed under the drainage basins. In addition, drum pumps are renowned for their low noise level.

The use of barrel units is also convenient because the water used for irrigation can be pre-diluted with fertilizers for feeding cultivated plants.

Most models are equipped with a pressure regulator. With its help, it is convenient to set the pressure necessary for work. The tank pumps have built-in filters to retain coarse particles.

But as noted by the owners who have already tested household models of this type, built-in filters do not always cope with the task at hand. As a result, even expensive systems quickly clog up and fail.

The easiest way to solve this problem is by arranging an additional home-made filter in the form of a cut from gauze or mesh tulle folded in 2-3 layers.

The pump is simply placed on a canvas suspended in a hammock so that the mesh between the suction device and the water does not allow debris to seep through.

You can prevent rust and sludge from entering the system by placing the pump inside the tank so that it does not reach the bottom of the tank by 5 cm.

Option # 2 - surface for shallow water

When planning to use an artificial reservoir or well as the main source of water intake, it is worth considering models of surface pumps.

They are placed in the immediate vicinity of the source, and water is taken by immersing a suction hose into the structure.

Outdoor devices are capable of pumping water from a depth of 8 m and delivering a jet to a level of about 30-50 m. Thanks to this pressure, several rows of beds can be watered from one point at once.

Most surface models use a metal pipe as the outlet. The rubber hose is not suitable for this purpose, because at the time of pumping the liquid, rarefied air is created inside it.

As a result: the elastic walls begin to contract, preventing the water flow from moving normally towards the exit.

The only drawback of pumps for irrigation from shallow water bodies is vibration and noise generation during operation.

You can get rid of the loud "growl" by placing the unit in an outbuilding, or by placing the unit body on a rubberized mat or stand.

Option # 3 - submersible for polluted ponds

Submersible pumps are rarely used for garden purposes. The working part of this type of device is immersed directly into the source, deepening below the water level. The pumped-out liquid under pressure is discharged to the surface through rubber pipes.

Depending on the type of model, submersible pumps are capable of pumping water from a depth of up to 80 m. This parameter is relevant when used as a source of water intake for irrigation of a drilled well.

According to the method of water supply, submersible irrigation pumps are presented in two versions:

  1. Vibrating. They work due to the movement of the membrane located inside. It causes pressure drops, under which water is first sucked in and then pushed out. Vibrating devices have a low price, but they are afraid of clogging with silt.
  2. Centrifugal. They raise water to the surface by rotating the blades and wheels. They "grind" the water with such force that they are not afraid of minor pollution. But such units are an order of magnitude higher than vibration ones.

The outer shell of submersible pumps can be made of stainless steel or plastic. Each of these materials is designed for permanent contact with designed for permanent contact with the working medium.

If it is necessary to use a pond as a source of water intake, the water in which is not particularly clean, the preference should be attributed to drainage models.

Such units are ways to "process" weakly and heavily contaminated water, which contains various kinds of impurities with a diameter of 5-10 mm.

The grinder located just above the suction device during pumping will crush leaves, silt and other debris that have got into the device along with water into the smallest particles.

Thanks to this, irrigation water will be additionally enriched with organic fertilizers, which will only have a positive effect on the yield of cultivated crops.

A significant drawback of drainage units used as pumps for irrigation from a pond is a weak pressure in the system. So you can water the garden with their help only by gravity.

If you plan to use a nozzle or a divider, then the water may not flow at all. You can get out of this situation by performing the work in stages.

First, with the help of a drain, fluid is pumped into the storage tank. And then, after it has settled and the heavy suspensions have settled, the garden is watered using a surface and submersible garden pump.

Option # 4 - automatic for drip irrigation

Automatic pumps equipped with timers are especially popular. They greatly facilitate the task of the owners who do not have the opportunity to waste precious time and excess moisture on watering for many hours.

Drip irrigation pumps are equipped with pressure switches and hydraulic accumulators. Control in such systems can be either manual or automatic.

Although such equipment is not cheap, the costs pay off over time, allowing more rational use of hundreds of cubic meters of moisture supplied during the season. And the owner frees up a lot of time that would have previously been spent on watering.


Pumps for pumping water from tanks

Among all the devices, the barrel irrigation pump is considered the easiest to maintain and connect. It is ideal for summer cottage purposes: it weighs little (up to 4 kg), works with containers whose depth does not exceed 1.2 meters, makes little noise and is easy to fix. They fix the pump directly on the barrel, insert the plug into the socket - and start watering. You can set the desired jet pressure yourself using the pressure regulator.The pumps have a built-in filter that will keep out debris and solid particles, so you can immediately pour fertilizer into the barrel and start watering with the ready-made solution.

The tank pumps are lightweight and easy to install, so they can be moved freely around the site while irrigating

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

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

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

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

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

Important! If you choose a system with a float switch, then you will not need to control how empty the barrel is. The pump will shut itself off as soon as the water level drops to minimum. Accordingly, the risk of breakage during dry running is eliminated.


Parameter definition

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

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

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

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

An example of calculating the head. The water mirror is at a distance of 6 meters from the surface, we will pump it from a depth of 8 m, it will need to be transmitted from the point of the fence to 50 m.The pipe is one inch, therefore we consider the horizontal head at 10 m.

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