Hydraulic piston pumps basic information:
Hydraulic piston pump is an important device in the hydraulic
system. It relies on the reciprocating motion of the plunger in the
cylinder body to change the volume of the sealed working chamber to
achieve oil absorption and oil pressure. Plunger pumps have the
advantages of high rated pressure, compact structure, high
efficiency and convenient flow adjustment. They are widely used in
occasions where high pressure, large flow and flow need to be
adjusted.
Hydraulic piston pumps features:
Axial Piston Variable Displacement Pumps are well engineered and
easy to handle.
Bearings of Variable Axial Piston Pumps are all tapered roller
bearing, which can load heavy external axial forces.
Hydraulic pumps can be connected with other additional pumps.
When Hydraulic 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 pumps has shaft oil seals performance, even at the lowest
temperature and high case pressure.
Servo valve of piston pump can connect function regulators and
remote control systems.
Axial piston pumps can easy maintain and can be disassembled and
assembled by standard tools. All components are replaceable.

Hydraulic piston pumps usage:
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.
