ECV pump - submersible, centrifugal, multi -sectional with a vertical location of the shaft is designed to raise water from artesian wells in order to carry out water supply, irrigation and other similar works.
The pump unit of the ECV consists of a well -bore pump and a submersible electric motor and is designed to lift water with total mineralization (dry balance) of not more than 1500 mg/l, with a hydrogen indicator (pH) from 6.5 to 9.5, a temperature of up to +25 ° C, and mass fractions of solids mechanical impurities - not more than 0.01%, with the chloride content - not more than 350 mg/l, sulfates - not more than 500 mg/l, hydrogen sulfide - not more than 1.5 mg/l.
Nominal linear voltage of the three -phase network 380V, 50Hz. The permissible voltage deviation is +10%, -5%. Synchronous engine speed 3000 rpm.
During the operation of ECV pumps, a backup should be provided, at least 1m, and for ECV1-200, 210, 250 pumps at least 2m.
ECV pumps are made with both threaded and flange accession.
The ECV pump body is made of cast iron or stainless steel. Work wheels are made of reinforced stainless steel of plastic, stainless steel, deaf cast iron, bronze (on order) and Noryl or Armlen.
