Most in acceptable in this situation is to install a submersible pump for the well or wells.
Compared with the pumping station, water well pump with a more complex and costly undertaking. This also applies to the price of imported Little Giant pumps and
installation costs of equipment and drilling.
Wells pump as opposed to a borehole has an internal cooling jacket engine, which increases its diameter and therefore can be placed only in a well or wells of large diameter.
Pit pumps are higher performance and lower cost for the same power consumption and pressure as that of the well pumps.
Engine Cooling borehole pump for the flow of water lifted, so for them there are minimally acceptable standards of water velocity. This fact also explains why the diameter of
the hole should not be much greater than the diameter of the pump.
For proper selection of parameters downhole pump can vospolzovatsya simple formula:
H (the desired pressure) = H (din.) + H (home) + H (nap.) + 20%
Hdin. – Distance from ground to the water level after the pump, m
Hdoma – distance from ground to the upper mark of rising water,
Hnap. – Pressure, providing the pressure in the water system (usually no more than 3 atmospheres or 30 meters of water column), m.
20% head loss in the plumbing pipeline.
Of course, this value is very approximate, and it strongly depends on the length of the pipeline.
In our market pumping equipment offers a large number of Russian and European pumps under the most demanding requirements. This pump manufacturers such as Livgidromash “,”
Livnynasos “,” ENA “, imported from a pump concern ESPA, Wilo, etc.
So that we can always choose the best option combination of performance, quality and price.
It should be noted that the operation of the downhole pump imposes several requirements:
Is a stable voltage, no more than + – 5%.
Mandatory installation of the check valve.
Protection against dry running (set poplovkovoy system, level sensors, or other protective devices)
