2cy series marine gear pumps are mainly composed of gears, shafts, pump bodies, relief valves, and shaft end seals. The gear has a higher hardness and strength after heat treatment, and is installed in a replaceable sleeve together with the shaft to run. The lubrication of all parts in the KCB gear oil pump is automatically achieved by using the output medium when the pump is working. There are reasonably designed oil drain and oil return grooves in the pump. The gears bear low torque during work, so the bearing load is small, the wear is small, and the KCB gear oil pump has high efficiency. 【High Pressure Gear Pump】 2cy series marine gear pumps are equipped with an overflow valve as overload protection. The total return pressure of the overflow valve is 1.5 times the rated discharge pressure of the pump. The KCB gear oil pump can also be adjusted according to actual needs within the allowable discharge pressure range. But note that this overflow valve cannot be used as a long-term pressure reducing valve, and can be installed on the pipeline when necessary. Looking at the pump from the extended end of the main shaft, it rotates clockwise.
