We select a motor-pump for watering the garden: types of units + selection tips

For water production, there are about a dozen types of special equipment. One of such units necessary in the economy is a motor pump for watering the garden. It is a mobile station equipped with a water pump, which is indispensable in suburban areas for arranging an irrigation system or creating a private water conduit. This technique is used not only for pumping water from wells and boreholes for the purpose of its further use as irrigation and domestic needs, but also for cleaning liquids and even cleaning sewage pits.

Autonomous units can significantly facilitate the management of non-electrified suburban areas. The motor pump is quite simple to use: it is easy to handle with any owner who has basic skills in working with equipment and has an idea of ​​the operation of the internal combustion engine.

The main advantage of motor pumps is their compactness and the ability to use with a wide range of work

The motor pump is easy to transport and does not require special storage conditions. It is easy to carry around the site, for convenience, dismantling the suction and discharge hoses.

The principle of the system is that under the influence of the movement of the impeller, a centrifugal effect occurs, which throws water in the pump casing into the "cochlea", which forms and directs a stream of water to the nozzle. As a result of the discharge that occurs near the rotation of the axis, the valve opens and fluid enters the nozzle. Water is taken and supplied to the pump through hoses attached to the nozzle.

To protect the pumping unit from large particles, the end of the suction hose is equipped with a strainer

What to look for when choosing a particular unit?

The requirements for the irrigation pump itself may be: tech / motopompa-dlya-poliva-ogoroda.html

Feature # 1 - Performance

Performance indicates the amount of fluid that a pump can pump per minute. It is this parameter that determines the appropriateness of using the unit for specific conditions.

For domestic needs of a small suburban area or the organization of irrigation of the garden with a motor pump, an aggregate with a productivity of 130-150 l / min is enough. Planning to provide water supply at home, you will need a more powerful unit, the performance of which varies in the range of 500-1000 l / min.

If the motor pump will be designed to drain the flooded areas, in fire fighting and other emergency situations, it is better to stop the choice on units with a high capacity of 1000-1200 l / min.

Less stringent requirements must be observed when selecting pumping systems for fountains and ponds: voda / nasos-dlya-fontana-i-vodopada.html

Feature # 2 - Engine Type

Depending on the type of engine, motor pumps are:

  • Gasoline;
  • Diesel;
  • Gas.

The power of units on a gasoline engine can reach up to 1600 l / min, which makes them effective both for pumping clean water and contaminated liquids. Gasoline-powered motor pumps are most popular among owners of suburban areas. The popularity of their application is explained by the ease of operation, high performance and relatively low cost of units. The only drawback of these types of models can be considered only a high fuel consumption.

Gasoline units are mainly equipped with a two- or four-stroke engine and operate on a mixture of gasoline and oil

The main advantage of diesel pumps is their reliability and durability. They are able to pump even viscous liquids.

When compared with gasoline analogues, the service life of diesel units is an order of magnitude higher and can reach 6000 hours. They are able to provide uninterrupted long-term operation with a fairly low fuel consumption. True, unlike gasoline models, they are quite noisy in operation. Although initially the cost of diesel motor pumps is quite high, but it quickly pays off due to the low price of diesel fuel during operation.

The smallest distribution in the management of the countryside received gas motor pumps. The reason for this is their high purchase price and the need to maintain special conditions during operation.

Due to the fact that gas, unlike gasoline and diesel, does not form ash and waste during combustion, the working surface of the unit wears out less, and the life of the engine is significantly extended.

On sale you can find both models that work exclusively on bottled gas, as well as more universal units that can also be connected to mains.

Feature # 3 - Maximum Head

Such a parameter as the water pressure at the outlet of the motor pump determines the distance at which the unit is able to transmit the injected water. The value of this parameter can hardly be overestimated in those cases when you have to work in conditions of a difference in height, to which you have to raise the pumped water.

For watering the garden and other household purposes, a motor pump with a pressure of 25-35 meters is enough, but it is still better to purchase a model with a pressure of up to 65 meters or more

This characteristic is also taken into account when selecting structures for pools: voda / kak-vybrat-nasos-dlya-bassejna.html

Variety of choice of motor pumps taking into account operation

Depending on the conditions of use, the motor pumps are divided into two subspecies.

Option # 1 - units for clean water

Such units are designed for filling containers, pumping water from the pool and watering the garden. They are equipped with filters capable of retaining solid particles over 6 mm, so that after filtration the water becomes relatively clean. On average, the performance of such motor pumps with two-stroke engines for watering the garden is 6-7 cubic meters / hour.

Water from pools, wells and springs is considered relatively clean. It practically does not contain impurities, dirt and large particles of garbage.

Mobile pumping stations for clean water easily fit in a backpack: they are lightweight and small in size.

Option # 2 - motor pumps for heavily polluted water

Such motor pumps are designed for pumping flooded areas, as well as cleaning the contents of wells and septic tanks. They are able to pump liquid in the composition of which a sufficiently high concentration of lime, clay, sand, silt, gravel or gravel can be present. Such models are equipped with filters that freely pass solid particles with a diameter of 6-30 mm.

The main advantage of such models is high performance and excellent bandwidth. Such motor pumps can be operated for a long time and with high intensity.

To cope with very dirty water containing sand, large particles of dirt and leaves, only motor pumps for highly contaminated water can

To choose the best option among the variety of models of motor pumps, it is necessary to clearly determine for what purposes it will be used. But, in any case, the unit with a gasoline engine, designed to pump dirty water, can easily cope with clean water.

However, during operation it will demonstrate greater fuel consumption than the same model, but with a diesel engine. It should also be borne in mind that the closer the motor pump is to the point of water intake, the less load will be on it.
