Pump, for water and other clean, chemically neutral liquids, single-stage cantilever, supply 301-25000 m3/h. Horizontal centrifugal cantilever pump with an electric motor. The basis of the pumping station of the PR line consists of horizontal centrifugal cantilever pumps (3 working + 1 standby), which are designed for use in complex technological processes. The geometry of the pump body is a double spiral with an end connector (radial division), with an axial suction nozzle and a pressure nozzle directed radially upwards. The end connector allows disassembly and repair of pumps without dismantling pipelines. The pump design ensures the removal of gases from the pump body during operation, when using a special vacuuming system. The radial impeller with volumetrically curved blades improves the hydraulic operation of the pump. The applied mechanical seal ensures the operation of the pump in the "dry shaft" mode to achieve a long service life of the pump shaft. Closed radial impeller with self-locking cap nut. The pump shaft support is made in an integral bearing housing with lubricated rolling bearings. The pump is mounted on a single frame with an electric motor connected through a special coupling.
