The pumps are mainly applied in 6-10 tons dump truck hydraulic system.
KP75B lifting gear 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 asintegration of pump and valve, which makes the pump being the ideal power source of dump truck hydraulic system.
