Pumps Submersible Artesian - Centrifugal well electric pump units of the ETSV type are designed to raise water with general mineralization (dry residue) of no more than 1,500 mg / l, hydrogen indicator of pH 6.5 - 9.5, temperature 25c, with a mass fraction of solid mechanical impurities no more than 350 mg / l, sulfates are not more than 500 mg / l, hydrogen sulfide is not more than 1.5 mg / l. Execution 1. Pumps with impeller fixed on the shaft. The axial hydraulic force is perceived by the reference device located in the electric motor. The clowful taps are stamped. Execution 2. Cylindrical cylindrical ropes are cut from pipes with discs, which fix taps in the axial direction, separated by the interenceneticness and form a slotted sealing of the working wheels. Execution 3. Pumps with licenses (potted) blades. Steps of pumps - semi - axis type. Wheels are fixed on the shaft. Execution 4. Monoblock Electric Aggregates (The impeller is located on the motor shaft). The aggregates of the performances X, G, TR and their combinations can be used with more stringent operating conditions defined in each case with specifications for a specific unit. Apply to lifting of artesian wells of clean water for use in urban, industrial and agricultural water supply. To control and protect the pumps such as ETSV, the Cascade, Height, etc. devices are designed.
