KP75S Hydraulic Gear Pump

KP75S Hydraulic Gear Pump


      KP75S lifting gear pumps are developed for the market in Southesat Asia. The position of valve rod is the same as KP1403 and KP55. The pumps are mainly applied in 6-10 tons dump truck hydraulic system as the hydraulic power source of bucket cylinder. Adopting the material of high strength casting iron and the advanced technology of double metal side plates with special structure to connect control-valve, return-valve and pump as a whole body, the pumps are featured of strong resistance of high working pressure, long lifetime, smart and simple hydraulic system as integration of pump and valve, which makes the pump being the idea power source of dump truck hydraulic system.
