We understand the types of garden pumps, their pluses and minuses.
When watering gardens and gardens, it is recommended to use pure and slightly heated water with a temperature of about 20 ° C, since very cold water from the well may damage plants. Therefore, garden pumps are in demand even in the presence of a common water pipeline.
Capacity with water is placed in the garden so that they can be filled from the source (well, well, water tap), for example, using a flexible hose, and then organize distribution during watering. Pumps for this are usually used not very powerful (pressure in 3-4 atm will allow the garden of any reasonable sizes) and not calculated on the pumping of water with sand and mud. All that is required from such devices is reliability and easy operation.
Types of pumps
Among the garden pumps there are models like submersible and superficial (self-priming).Submersible
Centrifugal
The absolute majority of all pumps belong to the centrifugal type: they are accelerating the water to be accelerated due to the centrifugal force of the rapidly rotating wheel. This design is characterized by economy, low noise, reliability and resistance to wear.

Pump garden 3000/4 (Gardena). Ergonomic handle provides convenience of transportation.
Vibration
Also there are vibration pumps ("Kid" and the like), the water is given acceleration at the expense of the returned movement of the piston (diaphragms).
Metabo P 3300 G pump
This design has the only dignity: low cost. But these pumps are less reliable, noisy and vibrate when working, lifting the bottom precipitate.
Submersible vibration pumps. NTV-210/10 model, power 210 W, consumption 12 l / min, pressure of 40 m (720 rubles)
Model "Forest Creek" VP 12B (Patriot). Power 300 W, consumption 18 l / min, pressure 50 m (1,900 rubles)
Surface
Surface is more convenient in operation. Self-priming device (ejector) allows you to raise water from a high depth when the water mirror (for example, well) is below the pump level by 7-8 m. And if the water capacity is at one level with the pump, then the remote ejector allows to suck water from the distance In 40-50 m. It is convenient, as it simplifies the water fence from several tanks. You do not need to carry a pump there and here, just throw the suction hose from one container to another.
Installation of water supply JP PT-H (Grundfos) with stainless steel housing and composite wheels. It can operate at air temperature to 55 ° C.

In this case, surface pumps are technically more complex devices. They are completed with protection from dry stroke, overheating, voltage jumps. In fact, they are a full-fledged base station, and they are often called them.

The price is above submersible. For example, high-quality JP or JP PT-H series from Grundfos will cost buyers of 15-20 thousand rubles. Inexpensive pumping station - 5-10 thousand rubles. Submersible vibration pump of domestic or Chinese production costs 1-2 thousand rubles. Drainage type submersible centrifugal pump can be bought in 3-4 thousand rubles. And for the same 8-10 thousand rubles. You will be offered a submersible garden pump with additional amenities. Kärcher is, for example, a special set for water supply from barrels, which includes a BP 1 Barrel pump with a filter, a hose with fasteners, a watering gun and other necessary parts. Gardena has a battery pump for rainwater tanks 2000/2 LI-18, which does not require connection to the network.
Pump for rainwater reservoirs Battery-free 2000/2 LI-18, feeds from removable battery 18 V
Surface pumps are more convenient, since it is not necessary to lower them into the water or hang on the cable, to ensure that water and the technique did not work in the tank.
Comparative Table of Surface and Submersible Pumps
| Type of pumps | Surface | Submersible |
|---|---|---|
| Benefits | Easy installation: can be installed at a distance of several tens of meters from the source (using ejector), it is possible to install inside the house.Easy to maintain | With a high depth of water (for example, a well depth of more than 8 m) may be the only available design option. Easy and low cost of design |
| disadvantages | More complicated in design and, as a result, more expensive | Some models work only fully immersed in water. There is no visual control over the operation of the pump |
Consumption and pressure
The main technical parameters of the pump are consumption and pressure.
Consumption (feed) is its performance, measured in m³ / h or l / s. For irrigation of the supply of 1-2 m³ / h, it will be quite enough. But if you wish, you can progress and choose a more powerful pump, with a capacity of 3-5 m³ / h. At the price, this will not affect the price, and the technique will be more universal.
GARDENA 3500/4 CLASSIC 4.0 pump
The pressure is a complete amount of energy reported by a fluid mass using a pump. The easiest way (although not very accurately) present this characteristic in the form of a height to which the pump can raise water, especially since the pressure is measured in meters. For the garden, there is enough pressure at 20-30 m, but if the water must be supplied for a large distance (more than 100 m) or there is a significant difference in the height on the ground, it is better to make a simplified test calculation of the hydraulic system before purchasing (using a specialist).

Important design features
- Draining. The design should allow you to completely drain the water so that the frosts do not bring the technique.
- The thickness of the water layer, in which the technique can work (for submersible pumps). Some models operate even with a layer thickness of 1 cm. This is important when pumping barrels, impressions and pools.
- Filter on the entrance nozzle. Delays pollution and extends the service life of the equipment.
Makita PF0410 pump
Protect pumping equipment from direct sunlight: usually there are parts from plastic parts that are destroyed under their impact.
The bright coloring of the case simplifies work with the technique in the garden, making it more noticeable.
Mikhail Terentiev, Head of Sales of Household Equipment "Grundfos"
The operation of pumping stations using asynchronous motors, to a large extent depends on the voltage. If the voltage becomes too big or too small, the station's performance decreases. In addition, voltage jumps can lead to increased engine wear and its breakdown. The output can be the use of pumping stations with an engine with a frequency converter. As for pumping tanks, the pump usually comes complete with an optimally selected tank. Therefore, buying an additional tank of more volume does not make sense - it will not affect the efficiency of the equipment. Large hydraulicists will not provide homeowner uninterrupted water supply in the situation of full turning off the electricity.
