Hydraulic Dump Truck

KP1405A lifting gear pumps are mainly applied in 10-20 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 simplehydraulic system as integration of pump and valve, which makes the pump being the ideal power source of dump truck hydraulic system. Performance parameter Theoretical displacement: 140ml/r Rated pressure: 80kgf/cm2 Steel cable force of controlling valve: 15kg Totalweight of oil pump: 37kg Max pressure: 210kg/cm2 Working conditions The temperature of hydraulic oil:-20°C-80°C Viscosity of hydraulic oil: 10-75c.s.t Oil filter precision: ≤=25um Oil suction height: ≤=500mm Drive: use flexible coupling bydirect drive Direction of rotation: counterclockwise (from shaft end of pump)
