Hydraulic piston pumps product description:
Highland 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.
Highland hydraulic 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.
