How to choose a pump for watering the garden with water from a pond, barrel or pond
Stable watering is a guarantee of getting a bountiful harvest from garden beds. If on rainy days the weather takes care of the plants, in the hot months it is up to the gardeners to solve it, using buckets and watering cans. To facilitate the work helps the use of pumping equipment.
What pumps for watering the garden offers a modern market and how to choose the right model, consider in the article.
The choice of source for water intake
The selection and purchase of a suitable model garden pump for irrigation depends on what kind of water is supposed to be pumped and from where it is planned to take.
Plants can not grow normally without a sufficient amount of life-giving moisture. But only well-settled warm water is suitable for watering green spaces.
Careful owners collect rainwater in barrels and large tanks located on the site under the gutters. If necessary, it remains only to get it, scooping up with a bucket or pumping out a pump for watering from the barrel.
Quite often, if there is a well or a well at the site, then water for irrigation is taken from them. But a “cold shower” can cause irreparable damage to the delicate roots of plants: they can start to rot.
For this reason, the water pumped from a hydraulic structure is first poured into containers, allowing it to heat up in the sun, and only after that is used for irrigation.
The third, and perhaps the most successful source, from where it is convenient to take water for irrigation, is a natural reservoir located nearby or an artificial pond built on its own.
In all the above sources of water according to the degree of contamination of water is very different. And because for each of them developed certain types of pumping equipment.
Types of pumps for pumping water
For irrigation of garden crops used two types of pumps. Depending on the method of water intake and placement of the body of the unit relative to the source, they are superficial and submersible.
Option # 1 - barrel for pumping tanks
Such devices are designed specifically for pumping water from tanks of small volume, the depth of which does not exceed 1.2 meters.
Among the pumping equipment on the market, such units are considered the easiest to use and maintain.
The main advantage of pumps for the production of irrigation from the barrel is compact and mobile. The average weight of the unit is 3-4 kg.
Taking it by the handle, it is convenient to carry it around the section and alternately install it on the containers placed under the catchments. In addition, drum pumps are known for their low noise levels.
The use of barrel aggregates 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 it, it is convenient to set the pressure necessary for work. Filters for large particles are built into the pumps for the tanks.
But as noted by the owners, have already tried out household models of this type, the built-in filters do not always cope with the task. As a result, even expensive systems quickly become clogged and fail.
The easiest way to solve this problem is by arranging an additional home-made filter in the form of a cut from folded 2-3 layers of gauze or net tulle.
The pump is simply placed on a canvas suspended in the form of a hammock so that the mesh layer between the suction device and water does not allow debris to leak.
Rust and sludge deposits can be prevented 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 - superficial for shallow reservoirs
When planning to use an artificial reservoir or well as the main source of water intake, it is worth considering models of surface-mounted pumps.
They are placed in the immediate vicinity of the source, and water is taken by immersion into the construction of the suction hose.
Outdoor devices can pump water from a depth of 8 meters and produce a jet to a level of about 30-50 meters. Due to this pressure from one point you can water several rows of beds at once.
A metal pipe is used as the outlet of most models of surface execution. The rubber hose is not suitable for this purpose due to the fact that at the time of pumping fluid inside it creates thin air.
As a result: elastic walls begin to contract, preventing the water flow from moving normally to the exit.
The only drawback of pumps for irrigation from shallow reservoirs is the vibration and the formation of noise during operation.
You can get rid of the loud "growl" by placing the unit in an economic building, 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 in the source, deepening below the water level. The evacuated liquid is pumped to the surface through rubber nozzles.
Depending on the type of model, submersible pumps are capable of pumping water from a depth of up to 80 meters. This parameter is relevant when used as a source of water intake for irrigation.drilled wells.
According to the method of water supply, submersible pumps for irrigation are presented in two variations of performance:
- Vibration.Work due to the movement of the membrane located inside. It causes pressure drops, under the action of which the water is first sucked in and then pushed out. Vibration instruments have a low price, but are afraid of clogging with silt.
- Centrifugal.Raise the water to the surface due to the rotation of the blades and wheels. They "grind" the water with such force that they are not afraid of minor pollution. But there are such units much higher than vibration ones.
The outer shell of pumps of submersible design can be made of stainless metal or plastic. Each of these materials is designed for continuous contact with designed for continuous contact with the working environment.
If it is necessary to use a pond as a source of water intake, the water in which is not very clean, preference should be given to drainage models.
Such units are methods of “processing” weakly and heavily polluted water, which contains various kinds of impurities with a diameter of 5-10 mm.
The grinder located just above the suction device during the pumping process will crush leaves, silt and other debris into the device with the smallest particles.
Due to this, irrigation water will be additionally enriched with organic fertilizers, which will only positively affect the yield of cultivated crops.
A significant drawback of drainage units used as pumps for irrigation from the pond is low 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, the water may not go at all. You can get out of this situation by completing the work in stages.
First, with the help of a drainage unit, the liquid is pumped into the storage tank. And then after it is settled and the heavy sediments are settled, the garden is watered using a surface and submersible garden pump.
Option # 4 - automatic for drip irrigation
Especially popular are automatic pumps equipped with timers.They greatly facilitate the task of the owners, who do not have the opportunity to waste precious time and excess moisture for hours of watering.
Pumps for drip irrigation are equipped with a pressure switch and hydraulic accumulators. Control in such systems can be both manual and automatic.
Although such equipment is not cheap, but the costs over time completely pay off themselves, allowing you to more efficiently spend hundreds of cubic meters of moisture supplied during the season. Yes, and the owner freed a lot of time that previously would have been spent on watering.
Criteria for the selection of units
Choosing pumping equipment, you need to determine for yourself the following factors:
- Distancefrom the source of water intake to the garden beds.
- Height differencefrom the installation site of pumping equipment to the extreme point of the garden.
- Plot sizeset aside for crops that need frequent watering.
- Watering type(radical, drip, sprinkling) and how often you plan to use it.
For drip irrigation is enough to install low-power equipment. When planning to irrigate crops through sprinkling, it is worthwhile to give preference to systems that can safely withstand a lot of pressure.
The most reliable are units with two-stage mechanisms. Such powerful units are chosen by the owners of large plots, which have a large area for garden beds, a flower garden and a garden in need of watering.
No. 1 - calculation of device performance
To calculate the required performance of the purchased pumping equipment usually take averages.
Depending on the climatic conditions and soil condition, according to the current SNiP, watering the beds of 1 square meter is required from 3 to 6 liters per day.
Therefore, for a garden with an area of 200 squares, the daily rate will be: 200x6 = 1200 liters.
The maximum productivity of barrel units makes 4000 l / hour. Choosing among low-power devices designed for pumping liquid from storage tanks, you should look at models with a capacity of 2000 l / h.
The price of such devices starts from 2.5 thousand rubles.
When arranging drip irrigation, the most reliable type of pump is centrifugal. After all, only he is able, without prejudice to the motor overheating, to pump large portions of water under high pressure for a whole day.
When choosing among drainage models, keep in mind that such units have a capacity of 83 to 250 liters per minute with a water supply of 5 to 12 meters.
When using water for irrigation from highly polluted reservoirs, the diameter of impurities of which is from 15 to 50 millimeters, it is worth choosing units with a capacity from 37 to 450 l / min. They are able to provide feed to a height of 5 to 22 meters.
No. 2 - recommended jet head
Under the pressure of the pump means the mechanical work of the unit, as a result of which the fluid pressure increases and it is pumped. In this case, part of the drive energy in the process of pumping is converted into the kinetic energy of the liquid.
The higher the value of the generated head, the greater the distance can be maintained between the pump and the source of water intake. When calculating the power, also consider that the ratio of the length of the vertical and horizontal is 1: 4.
At the same time, when it comes to watering, too much pressure is more trouble than good. After all, the expulsion pressure can not only damage the dividers, tearing them off the hose, but also harm green plantings.
No. 3 - availability of automation system
Automation significantly increases the cost of pumping equipment. But it plays a significant role, preventing overheating of the "heart" of the unit - the motor.
A float switch protects the instrument engine when the specified minimum water level is reached. This prevents the unit from “running dry”, thereby minimizing the risk of breakage.
Having chosen a unit equipped with a float switch, during operation you will not need to control how empty the barrel is.
You are only required to flush the float switch under the pressure of the water only once a season to prevent the box body from sticking to the outlet.
No. 4 - location of the suction valve
The suction valve can be located above the engine compartment in the upper part of the device, or in the bottom of the case.
More practical model, the water intake which is located in the upper part of the body. Such a constructive solution reduces the likelihood of silting and penetration of sediment and sand particles into the chamber.
When using submersibles for irrigation, the suction valves of which are located in the bottom of the housing, use special supplies.
By placing the pump on a stand, you can partially protect the working chamber from the entry of fibrous inclusions, heavy sand suspension and large debris.
The pumps usually include adapters that allow you to connect flexible hoses and rigid pipes with a diameter of 1ʺ and 11/4ʺ. In budget models, most likely, a watering hose and spray nozzle will have to be purchased additionally.
Overview of manufacturers of pumping equipment
High demand for pumping equipment for domestic use encourages manufacturers. Today, foreign and domestic manufacturers offer a wide range of equipment in different price categories.
Imported global brands
Among foreign manufacturers, well-established in the pumping equipment market, it is worth highlighting:

Among the companies that are only increasing their potential, but have already earned a positive reputation among a wide range of consumers, it is also worth highlightingMakita"And"Gardena».
Popular brands of pump equipment of domestic producers:
- "Vortex".Leading Russian manufacturer.The main advantage of the products is convenience in operation, quiet operation and minimal hydraulic losses in the process of pumping.
- "Dzhileks".The Russian company produces reliable pumps that can be used as pumping clean and slightly polluted water for irrigation.
- "Gardener".Products manufactured under this brand successfully combine an affordable price with decent quality. Compact centrifugal devices easily handle contaminated water.
The price of centrifugal submersible pumps of these brands starts with a mark of 4 thousand rubles. Drainage units of average power cost from 5 thousand and above.
Low-cost models of domestic production, “Rucheek” and “Malysh” are also very popular. The price of products ranges from 1.5-2 thousand rubles.
But it is worth noting that they are very sensitive to voltage fluctuations in the electrical network. To work in our conditions, it is better to choose centrifugal models for which no such sin has been noticed.

And finally, I want to note that,regardless of the model chosen, equipment deficiencies are most often manifested due to improper handling.
If the device is designed for pumping clean water, then you should not lower it into the tank with rainwater. Fallen leaves and sand will quickly clog the filters and disable the device. And it’s not the producer who is to blame for this, but only an impolite owner.
