Pumps of the Model-Sensible series NShR300/210 ... 800-02 are designed to pump water and other neutral liquids similar to water in density and viscosity, with the hydrogen indicator pH4.0 ... 8.5, with a temperature of up to 70 ° C, with the content of sulfates and chlorides up to 350 mg/l, mechanical impurities in size up to 1 mm and their mass concentration of up to 1.5%.
Pumps can be used in mine water disposal systems, in water supply systems, in explosive and fire hazardous industries (subject to the application of the appropriate execution of the drive engine).
The warranty life of the pump is 12 months from the date of commissioning, but not more than 18 months from the date of shipment from the manufacturer. />
The service life is up to the 1st overhaul, hour: at least 15000.
The average full service life is at least 8 years.
Useful action - 77%.
Power supply parameters are a characteristic of drive engines and are determined by the engine supplier.
Design: Centrifugal horizontal pump, multi-stage with hydraulic unloading of axial force (with hydro-adoles). Rotor supports are two sliding bearings with an annular lubricant supply.
Materials: The main details of the prototype part: working wheels, guide devices, slotting parts and shaft seals are made of chromium stainless steel. The materials used in the pump design provide a high resource and maintainability of the product.
