HPV90 big displacement hydraulic piston pumps for drilling machines
HPV90 hydraulic piston pumps:
By designing and manufacturing static hydraulic transmission,
Highland hydraulic can provide axial hydraulic pump and hydraulic
motor assembly and hydraulic system with high quality,
high-performance parameters. Hydraulic piston pump is the variable
one that is with Charge Pump, and the motor the quantitative, or
variable one with valve assembly. The control way of variable
displacement pump and motor can be manual or hydraulic operated,
and can simply control speed, direction and power of the output
shaft of hydraulic motor. It is widely used in agricultural
machinery, engineering machinery, mining machinery, aviation and
transport hydraulic engineering machinery and other equipment.
HPV90 Hydraulic piston pumps features:
- Axial variable displacement piston pump
- Have swash plate structure
- Be Suitable for hydrostatic transmissions with closed loop circuit.
- Variable displacement pumps with a charging oil pump and fixed
displacement motor with an integrated valve.
- Manual servo and hydraulic variable control

Hydraulic piston pumps main features:
- Series 20 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.
Application range of hydraulic piston pumps:
It is widely used in agricultural machinery, engineering machinery,
mining machinery, aviation and transport hydraulic engineering
machinery and other equipment.
