KCB gear pump is suitable for conveying lubricating oil containing no solid particles and fibers, non-corrosive, temperature not higher than 80 ° C, viscosity of 5×10-6～1.5×10-3m2/s (5-1500cSt) or similar Other liquids for lubricating oil. 1.KCB gear pump mainly consists of gear, shaft, pump body, safety valve and shaft end seal. 2. The gear has high hardness and strength after heat treatment, and is installed in the replaceable bushing together with the shaft. Lubrication of all parts in the pump is automatically achieved by the output medium during pump operation 3. The pump has a well-designed oil drain and oil return groove, which is the minimum torque force that the gear can withstand during work. Therefore, the bearing load is small, the wear is small, and the pump efficiency is high. 4.KCB18.3——83.3 main drive gear is a pair of helical gears, direct-acting safety valve
