Central heating pump 400-240, 400 kW, 1500 rpm multistage, without motor

Industrial centrifugal sectional (multistage) pumps CNS and CNS(g) are a series of high-performance water pumps. They are designed for pumping technical water with a hydrogen index of pH 7...8.5, with a mass fraction of mechanical impurities of no more than 0.05%, a solid particle size of no more than 0.2 mm, and a microhardness of no more than 1.47 hPa (147 kgf/mm2). CNS pumps are designed for pumping water with a temperature of up to +45°C, and CNS(g) - for pumping water with a temperature of from +45°C to +105°C. Pumps and units are manufactured in a general industrial version and cannot be used in explosive and fire-hazardous production facilities. The main areas of application of CNS pumps are cases of increased volume of pumped liquid, for example, for housing and communal services enterprises (water supply), as well as pumps for the mining and quarrying industry.
