For the extraction of water there are about a dozen types of special equipment. One such important household units acts as a pump for watering the garden. It is a equipped with a water pump the mobile station, which is indispensable in suburban areas for construction of irrigation system or create a private conduit. This technique is used not only for pumping water from wells and boreholes with a view to further use it as irrigation and domestic needs, but also for cleaning liquid and even sewage pits.
The contents
Autonomous units have a considerable impact on agriculture over the non-electrified rural areas. Pump is fairly simple to use: easy to handle any landlord owning the basic skills of working with equipment and having an idea of the internal combustion engine.
The main advantage of motor pumps is their compactness and possibility of use in a wide range of works
Pump easy to transport and does not involve special storage conditions. It is easy to transfer on the site, for the convenience of dismantling sleeves suction and discharge.
The principle of the system lies in the fact that under the action of the movement of the impeller centrifugal effect occurs, which discards water into the pump body in «the snail», forming and guiding the water jet nozzle. As the result of dilution occurring near the rotation axis, the valve opens, and fluid enters the nozzle. Water abstraction and supply it to the pump is via a pipe attached to the hoses.
To protect the pumping unit from the ingress of large particles the suction hose end is equipped with mesh filter
What to look for when selecting a unit?
Feature #1 — performance
Productivity indicates the amount of fluid that is able to pump the pump per minute. This parameter is the determining factor in the appropriateness of a unit for specific conditions.
For domestic purposes a small suburban area or irrigation garden pumps sufficient aggregate capacity 130-150 l/min Planning to ensure water supply to the house, you will need a more powerful machine, the performance of which varies in the range of 500-1000 l/min..
If the pump is designed for draining flooded areas, fire fighting and other emergency situations, the choice is better to stop for units with high performance in 1000-1200 l/min.
Feature #2 — engine type
Depending on the type of engine the pumps are:
- Gasoline;
- Diesel;
- Gas.
The capacity of the units of a petrol engine can reach up to 1600 l/min, making them effective for pumping of pure water and polluted liquid. Pumps powered by gasoline, are the most popular among owners of country houses. The popularity of their use is due to simplicity of operation, high performance and relatively low cost units. The only disadvantage of such type of models can only be considered a high fuel consumption.
Petrol units are equipped with mainly two – or four-stroke engine and working on a mixture of gasoline and oil
The main advantage of motor pumps and diesel engine is their reliability and durability. They are able to pump even viscous fluids
When compared with gasoline counterparts, the life of diesel engines much higher and can reach 6000 hours. They are able to provide uninterrupted long-term work with a fairly low fuel consumption. However, unlike the petrol models, they are quite noisy in operation. Though initially the cost of diesel water pumps is quite high but it pays for itself quickly due to the low price of diesel fuel in the process of operation.
The least common in the conduct of country farms were gas pumps. The reason for this is their high purchase cost and the necessity of maintaining special conditions in the process of operation.
Due to the fact that gas, unlike gasoline and diesel, when burned, does not form ash and waste, the working surface of the unit less wear and engine life is greatly prolonged.
The sale can be seen as a model, working exclusively on bottled gas and more versatile units that can be connected and trunk.
Feature #3 — maximum pressure
This option, as the water pressure at the outlet of the pumps, determines the distance the unit is able to transmit the injected water. The value of this parameter is difficult to overestimate in cases when you have to work in conditions of drop height at which the pumped water has to be raise.
For watering the garden and other domestic purposes, it is sufficient pump pressure at 25-35 meters, but it’s better to buy a model with a pressure of up to 65 meters and more
A variety of water pumps taking into account the exploitation
Depending on the conditions of use pumps are divided into two subspecies.
Option #1 — units for clean water
These units are designed for filling containers, pumping water from the pool and watering the garden. They are equipped with filters that can hold solid particles over 6 mm, so that the water after filtration is relatively clean. On average, the performance of such inner lining with two-stroke engines for watering the garden is 6-7 cubic meters/hour.
Water from swimming pools, wells and springs is considered to be relatively clean. It contains almost no impurities, dirt and large debris
Mobile pumping stations for clean water can easily fit in a backpack: they are light weight and small dimensions.
Option #2 — pumps for heavily contaminated water
These pumps are designed for pumping of flooded areas and clear the contents of the wells and septic tanks. They are able to pump fluid which may contain a high concentration of lime, clay, sand, silt, gravel, or crushed stone. These models are equipped with filters, freely passing the solid particles with a diameter of 6-30 mm in.
The main advantage of these models is the high performance and excellent throughput. Such pumps can be operated for quite a long time and with high intensity.
To cope with very dirty water containing sand, large particles of dirt and leaves, can only pump for heavily polluted water
To select the best option among the variety of models of the inner lining, it is necessary to clearly determine the purposes for which it is used. But, in any case, the unit with petrol engines, designed for pumping dirty water, easy to handle and clean water. However, in the process of operation it will show higher fuel consumption than the same model, but with a diesel engine. Also note that the closer the pump is to be to the point of abstraction of water, the less will be the load.
