The plunger pump is an important device for the hydraulic system. It relies on the plunger to reciprocate in the cylinder to change the volume of the sealing working chamber to achieve oil absorption and oil pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment.
Piston pumps are widely used in applications where high pressures, high flow rates, and flow rates need to be adjusted, such as hydraulic presses, construction machinery, and ships.
The plunger pump is generally divided into a single plunger pump, a horizontal plunger pump, an axial piston pump and a radial piston pump.
