Applications: designed for pumping condensed waste steam from stationary steam turbines and heating steam condensate (drain water) from heat exchangers in the thermal power stations that burn organic fuel. May be also used to transfer water in heating plants and water supply systems. Design: aksv series pump units consist of a centrifugal pump and an induction motor mounted on the motor stool. They are connected by means of a rubber-bushed (pin-and-bushing) flexible coupling. The pumps are electrically driven vertically suspended, can diffuser, single-stage (ksv 125-55) or multistage centrifugal pumps with inducer and single flow impeller arrangement (with all the impellers facing the same way). An outer casing (barrel) and an inner casing (withdrawable element or cartridge) are the major pump components. The barrel is a construction made of steel plate by complete welding process, which integrates a suction chamber (in the form of a can) and a discharge chamber (the discharge head proper). Pump support feet and weld-end suction and discharge nozzles are welded to the barrel. The inner casing (a rotating assembly) of ring-section type comprises a bare rotor, a shaft seal bearings, stage casings with built-in diffusers and a delivery cover. The design of pump shaft seal chamber provides for both housing a mechanical seal (-t) and packing the stuffing box (-s). The shaft of the pump make КсВ 125-140-3М is sealed only by means of packed gland.
