Piston pumps are divided into two representative structural forms: axial piston pumps and radial piston pumps; since radial piston pumps are a new type of high-efficiency pumps with relatively high technical content, with the continuous acceleration of localization , Radial plunger pump will inevitably become an important part of the application field of plunger pump.

The plunger pump is a kind of reciprocating pump, which belongs to the volume pump. The plunger is driven by the eccentric rotation of the pump shaft and reciprocates. Its suction and discharge valves are all one-way valves. When the plunger is pulled out, the pressure in the working chamber decreases and the outlet valve closes. When it is lower than the inlet pressure, the inlet valve opens and the liquid enters; when the plunger is pushed inward, the working chamber pressure rises and the inlet valve closes. The outlet valve opens and the liquid drains.
