Purpose and area of application

Centrifugal electropump is intended for water lifting from boreholes

Advantages

• resource of work before major repair increased in 2 - 3 times;
• ability to work in sand holes at a mass fraction of sand in water up to 0,1 - 0,2 % (for analogues it is up to 0, 01);
• high economic facility;
• low cost.

Features of construction

The aggregate is supplied with the cyclonic chamber for cleaning of sand from water, which comes for cooling and lubrication of bearings.
The hermetic engine is applied for a drive of the pump. The engine filled with a nonfreezing liquid which protecting it from corrosion.
For sliding surfaces the diamond burnishing was applied and at manufacturing working wheels - balancing.
