Product Description

Road roller machine hydraulic piston pumps easy to operate

Highland Hydraulic piston pumps basic information:

Highland Hydraulic piston pump is an important device in the hydraulic system. Hydraulic piston pump 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. 

Hydraulic piston pumps of road roller features:

Hydraulic piston pumps are well engineered and easy to handle.

Bearings of piston pumps are all tapered roller bearing, which can load heavy external axial forces.

When hydraulic piston pumps operated mechanically, the servo displacement can control and keep the angle of swash plate and pump displacement.

The project documentation is supported by product technical parameters, engineering drawings and a factory performance test report for the HPV30-MA-R-21.

This project reference demonstrates the documented application of the HPV30 series in concrete mixer truck equipment and provides application-specific technical evidence for customers evaluating the pump for similar hydraulic systems.

Factory Performance Testing

Before dispatch, every HPV30-MA-R-21 closed-loop axial piston pump undergoes a controlled performance test to confirm its principal operating characteristics.

The unit tested was run on 17 September 2025 at a test temperature of 27.3°C, with a rated displacement of 30 mL/rev, a rated pressure of 35 MPa and a peak pressure of 42 MPa.

The test captured pump speed, outlet pressure, flow rate, displacement, input torque, input power, output power, overall efficiency and volumetric efficiency. Each report names the component model HPV30-MA-R-21 and carries a unique component number for full traceability.

This gives engineers and buyers product-specific measured data instead of relying solely on nominal catalogue figures.

Recorded Test Data

Recorded on the factory test bench, the data for the HPV30-MA-R-21 hydraulic pump are presented in the following table.

Test conditions were as follows:

• 27.3°C test temperature
• 30 mL/rev rated displacement
• 35 MPa rated pressure
• 42 MPa maximum pressure
