Advantage of pumps is their application on pumping the circulating water in low-pressure heating systems. Pumps are intended for pumping clean or slightly polluted water with contain of mire up to 2%, or with contain max. 7% weight of solid mechanical addition (sand, crushed material etc).
The pump series NVM are the horizontal one stage volute pumps with their branches located "in line" what allows connecting pump directly on pipeline. The pump consists of hydraulic and electric part, what composes monoblok. The pumps having their internal area of branches DN 50 are griped only into the pipeline, which in specified length transfer whole weight of pump. The pumps having their internal area of branches DN 65, 100 are griped on the base plate and fixed to the pipeline. The highest allowed head is 0,3 MPa. The seal is mechanical.
LC - volute casing, intermediate piece, impeller, wearing ring and impeller nut - grey cast iron, shaft - constructional steel
Selection of pump material version is according to pumping liquid
monoblok version
