pumping units of the ECV type are designed to supply water from wells with total mineralization (dry balance) of not more than 1,500 mg / l, with a hydrogen indicator (pH) from 6.5 to 9, 5, with a temperature of up to 25 ° C with a mass fraction of solid mechanical impurities 0.01% (100 g / m 3 > ), the chloride content of not more than 350 mg / l, sulfates - no more than 500 mg / l, hydrogen sulfide 1.5 mg / l.
units can be used for urban, industrial and agricultural water supply, for irrigation, reducing groundwater level and for domestic needs.
units operate in long mode from the 380-phase current network with a voltage of 380 in a frequency of 50 Hz.
The designation of the standard size includes: ECV letters (E - with a drive from the deep electric motor, c - centrifugal, V - for water supply) and numbers consistently indicate: the permissible diameter of the casing in inches (diameter in mm, reduced 25 times and rounded), nominal representations (in the d. ; TOP: -0.5em; "> 3 /h) and the pressure (in m) corresponding to the nominal feed.
pump units are made in two performance:
1. ECV
2.
3. ECV with the letters of the HCC (stainless steel, stainless steel, graphite submarine).
No.
