[0002] The plunger pump is a common volumetric hydraulic pump, which realizes the suction and discharge of liquid through the reciprocating movement of the plunger in the cylinder. Its characteristics are high pressure, high efficiency and compact structure. The plunger pump needs to be connected with multiple pipelines for liquid delivery, so there are many communication pipe fittings matched with the plunger pump.
