Hydraulic Dump Truck

KP55A lifting gear pumps are mainly applied in 4-6 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 ideal power source of dump truck hydraulic system. Theoretical displacement: 55ml/r Rated pressure: 70kgf/cm2 Steel cable force of controlling valve: 13kg Totalweight ofoil pump: 13kg Oil filter precision: ≤25um Oil suction height: ≤500mm Drive: use flexible coupling by direct drive Direction of rotation: counterclockwise (fromshaft end of pump)
