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 pumping unit of the ECV It consists of a well pump and a submersible electric motor and is designed to raise 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, mass fraction of solid mechanical impurities - no more than 0.01%, 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.
nominal linear voltage of a three -phase network 380V, 50Hz. The permissible voltage deviation is +10%, -5%. The synchronous speed of engine rotation is 3000 rpm.
when operating EDC pumps, a back should be provided, at least 1m, and for pumps ECV12-200, 210, 250 at least 2m.
pumps. EDCs are made both with threaded and flange accession.
the ECV pump body is made of cast iron or stainless steel. The work wheels are made of reinforced stainless steel of plastic, stainless steel, deaf cast iron, bronze (on order) and the material of Noryl or Armlen.
