This series of pump is composed of replaceable cartridge kits, which reduce the construction time thus enhance production efficiency. Optimum design of pump core further reduce the pressure shimmy, flow pulsation and noise of the pump. Reliable pressure balance which compensate the space can have better capacity efficiency. The proper design of oil supply system between vane and intra-vane enables good contact between vane and stator and ensure minimum flow loss. The unique design, high-precision processing and rational material selections prolong the service life of the pump.
