The plunger pump is an important device in the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil absorption and pressure. Piston pumps have the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment. They are widely used in situations where high pressure, large flow and flow need to be adjusted, such as hydraulic presses, engineering machinery and ships.
