What Is A Plunger Pump?

The plunger pump is a hydraulic pump, the plunger pump mainly has a single plunger pump, horizontal plunger pump, axial plunger pump, radial plunger pump and straight axis swash plate plunger pump.

The working principle of the plunger pump is to change the volume of the sealing working chamber by changing the stroke length of the plunger in the cylinder block, so as to achieve oil absorption and oil pressure, so that the oil in the hydraulic system flows up. The plunger pump is mainly composed of power part and hydraulic part, and is equipped with check valve, safety valve, regulator, lubrication system and so on. The piston pump is powered by the eccentric rotation of the pump shaft, and its suction and discharge are one-way valves.

Plunger pump is also called high pressure pump, because of its reciprocating movement in the high seal cylinder, can produce higher pressure, so the plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow regulation. It is widely used in high pressure, large flow and flow need to be adjusted, such as hydraulic press, construction machinery and ships.
