  • - urban and rural water supply;
  • - irrigation, watering and irrigation systems;
  • - industrial water supply;
  • - mining industry;
  • - pressure increase systems;
  • - lowering the level of groundwater.

Operating conditions

Units 2. ECV 10 is designed to raise water from artesian wells with total mineralization (dry residue) not more than 1500 mg/l, with a hydrogen indicator (pH) from 6.5 to 9.5, temperature up to 25 ° C, and mass fraction of solids mechanical impurities - not more than 0.01%, more than 0.1 mm in size, with a chloride content - not more than 350 mg/l, sulfates - not more than 500 mg/l, hydrogen sulfide - not more than 1.5 mg/l.

Design features:
  • - Designed for lifting water from wells with a minimum inner diameter of 249.2 mm;
  • - compactness and reliability give the possibility of horizontal installation;
  • - a checklist check valve made of stainless steel;
  • - shaft of high -pressure stainless steel pumps;
  • - number of launches per hour: 10, interval between inclusions/switching 90 seconds;
  • - water flow rate along the pump electric motor
  • - The coupling connecting and the pump shaft are made of stainless steel;
  • - Submarine and head are made of steel with a polymer coating.
