GPG55 lift pump (from the Big Dipper pump) is mainly used for 4-6 tons of Japanese style dump truck’s hydraulic system, as the side of the hydraulic bucket cylinder power source. The pump uses high strength cast iron material. The ability to withstand strong internal structure using dual-gold side plate, control valve and check valve in conjunction with the pump body and many other advantaged technologies. The pump has a high work pressure, long service life. The character of the hydraulic system to simplify integration is an ideal power source for the hydraulic system of dump truck.
