Submersible borehole pumps type ETsV
Submersible borehole pumps type ETsV
The ETsV centrifugal downhole electric pump unit for water is designed for urban, industrial and agricultural water supply, pressure increase, irrigation, formation water pumping, water drawdown, etc.
Pumps of the ETsV type are designed to lift water with a total mineralization (dry residue) of not more than 1500 mg / l with a pH value (pH) of 6.5 to 9.5, a temperature of up to 25 ° C, with a mass fraction of solid mechanical impurities not more than 0.01%, with a content of chlorides not more than 350 mg/l, sulfates not more than 500 mg/l, hydrogen sulfide not more than 1.5 mg/l.
The electric pumping unit ETsV consists of a centrifugal pump and a motor, the shafts of which are interconnected by a coupling. The suction cavity of the unit is protected by a mesh from the ingress of large particles. The pump is connected to the engine with studs. The casing protects the motor outputs from mechanical damage.
The unit is under water during operation.
