Hydraulic piston pumps product description:
The hydraulic piston pumps are the power component of the hydraulic system. Its function is to supply the oil with a certain flow and pressure to the system, so it is also the core component of the hydraulic system.
The piston pump is divided into axial piston pump and radial piston pump according to the structure. Our hydraulic piston pumps are axial piston pumps.
Hydraulic piston pumps features:
- Hydraulic piston pumps can be connected with other additional pumps.
- When Hydraulic piston pumps operated mechanically, the servo displacement can control and keep the angle of swash plate and pump displacement.
- Upon release of the control handle, swash plate return to zero position automatically and the flow reduces to zero.
- Hydraulic piston pumps have shaft oil seals performance, even at the lowest temperature and high case pressure.

Hydraulic piston pumps usage:
a. Piston pumps are widely used in high-pressure, high-flow, high-power systems and occasions where the flow needs to be adjusted, such as agricultural machinery, construction machinery, mining and metallurgical machinery, and ships. It can play an important role.
b. Piston pumps are used in petroleum exploration and development, petrochemical, pharmaceutical, atomic energy science, environmental science, process equipment, experimental equipment, etc.
Hydraulic piston pumps notices:
The service life of the piston pump is related to the usual maintenance, the quantity and quality of the hydraulic oil, and the cleanliness of the oil. It is also an effective way to prolong the life of the piston pump to avoid the wear and tear of the friction pair of the plunger pump caused by the particles in the oil. The higher the cleanliness of the hydraulic oil, the longer the service life of the hydraulic pump.
