KCB stainless steel gear pump mainly consists of gear, shaft, pump body, valve and shaft end seal. The gears are heat treated to have a high hardness and strength and are mounted with the shaft in a replaceable bushing. Lubrication of all parts in the pump is automatically achieved with the output medium while the pump is operating. The KCB stainless steel gear pump has a well-designed oil drain and oil return groove. The torque of the gear is small during operation, so the bearing load is small, the wear is small, and the pump efficiency is high.
