Submersible pumps like ETsV

ETsV — pumps one - or much step with a vertical arrangement of a shaft; work with a podpor. Size a subtime for each pump under normal conditions works is specified in a technical characteristic.

Steps of pumps of radial or semi-axial type. Bearings of the pump and the electric motor are greased and cooled with water. Pumps are equipped with backpressure valves of dish-shaped or spherical type which hold a water column in the pipeline at stops of the pump and facilitate restart of the electric pump unit, and the special pressure head branch pipes intended for connection of the unit to the water-pressure pipeline.

The pumped-over environment: no more than 0,01%, the content of chlorides no more than 350 mg/l, sulfates — no more than 500 mg/l, hydrogen sulfide — no more than 1,5 m are intended for rising of water by the general mineralization (the dry rest) of no more than 1500 mg/l, a hydrogen indicator rn 6,5-9,5, with the temperature up to 298 To (25 °C) with a mass fraction of solid mechanical impurity

For the pumps working at chemically active water, at water with the increased temperature or at water with the increased content of solid mechanical impurity in a symbol after number have to respectively Tr, is added by HTR, HTRG of a letter X:
— for water supply with a mineralization no more than 2500 mg/l;
X \for water supply with a mineralization no more than 2200 mg/l;
HTR — for sea water with a temperature from-2 to +30 °C;
HTRG — for yodo-bromic water with a temperature up to 70 °C of g/l.

Symbols: 3ETsV6-16-60ХТрГ
3 — execution of the pump
E — with the drive from the submersible electric motor;
C — centrifugal;
In — for water supply;
6 — the most admissible for this standard size the internal diameter of an upsetting column (well) reduced by 25 times and rounded;
16 — giving, m3/hour;
60 — a pressure, m
