НШР300/210…800-02 pumps

Pumps of НШР300/210…800-02 type and size range are intended to pump water and other neutral liquids similar to water by density and viscosity, by hydrogen indicator pH4,0…8,5, by temperature up to 70°C, by the content of sulfates and chlorides up to 350 mgr/l, mechanical impurities of size up to 1 mm and mass concentration up to 1.5%.

Pumps can be used in the systems of mine drainage, in water supply systems, in explosion and fire risk productions (in conditions of using a drive motor of corresponding production).

Lifetime before the first overhaul, hours: not less than 15000.
Average full life time is not less than 8 years.
Efficiency is 77 %.

Electric supply parameters are determined by drive motors and defined by motor suppliers.

Design: Pump is centrifugal, horizontal, multistage, with hydraulic unloading of axial power (with hydraulic balancing device).
Rotor supporters are two plain bearings with ring lubrication.

Materials: The main details of the running part: operating wheels, guide vanes, details of gap seals and shaft seals are made from chrome stainless steel. Materials used in the pump design prove the product’s high capacity and reparability.
