The core oil outlet joint plunger element for Pump elements

The pump unit, also known as the plunger pair, is the core component of the electric grease lubrication pump, precision machined from bearing steel and equipped with a built-in check valve. The highest pressure can reach 25Mpa, the minimum matching gap is 3-5um. The rated displacement is 0.12cc or 0.18cc. The pump element transports lubricating pressure fluid, and at the same time generates back pressure on the working resistance of the connected actuator.The function of the pump element is to make the piston of the pump element push and pull through the eccentric wheel to suck in the grease or oil in the element cavity, and then pressurize the grease or oil into the pipeline.
