Pump borehole

Etsv pumps - borehole pumps centrifugal vertical , Pump etsv - is a unit consisting of multistage centrifugal pump and submersible electric motor with a rigid coupling of the shafts., with a closed impeller single inlet. Pumps ECV, Designed to lift water with a total mineralization of not more than 1500мг/l, hydrogen...pH 6.6 to 9.5, with temperatures up to 25 °C, with a mass fraction of solid mechanical impurities not more than 0.01%, chloride content not more than 350 mg/l, sulphates not more than 500 mg/l, hydrogen sulphide not more than 1,5 mg/l. flow parts Material – cast iron, glass filled polyamide, stainless steel.

For control and protection of pumps ECV is designed the device "Cascade", "Height","Susa".

Submersible Pumps, Pumps etsv – multi-stage with vertical shaft arrangement, working with support (distance from water surface to the discharge flange of the pump – provides wetting of the upper bearing when starting and escavation the pump). The magnitude of pressurization is 1 meter. Stage pumps etsv – radial and side types. Pump bearings and motor are lubricated and cooled by water. Working position of the Assembly is vertical.Designation: pump etsv 6-16-110.where • e – drive from submersible electric motor• C - centrifugal• for water supply• 6-the minimum allowable internal diameter of boring casing, mm, reduced by 25 times and rounded;• 16-supply, cubic m/h;• 110 - pressure,M.
