Self-Propelled Mower Hydraulic Piston Pumps 170kw Axial Piston Pump

Product Description

Weeding machines axial hydraulic piston pumps easy to maintain

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 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.

Factory Performance Testing

Each hydraulic piston pump in the HPV70 series is supported by a documented closed-loop hydraulic pump performance test record.

The report identifies the assembly as HPV70-MA-R-21, rated at 70 mL/rev, with the test dated September 14, 2026 at 26.8°C.

Documented values include operating speed, pressure, flow, displacement, torque, input power, output power, overall efficiency and volumetric efficiency, across pressure points from approximately 5 MPa to 30.6 MPa.
