The project documentation is backed by product technical parameters, engineering drawings and a factory performance test report for the HPV50-MA-R-21.

This project reference illustrates the documented application of the HPV50 series in concrete mixer truck equipment, giving customers application-specific technical evidence when evaluating the pump for similar hydraulic systems.

Factory Performance Testing

A factory performance test is carried out on the HPV50-MA-R-21 closed-loop axial piston pump prior to shipment, checking its main operating behaviour under controlled conditions.

This unit was tested on September 14, 2026 at 31.4°C; its rated displacement was 50 mL/rev, rated pressure 35 MPa and maximum pressure 42 MPa.

Measurements recorded during the test comprised pump speed, outlet pressure, flow, displacement, input torque, input power, output power, overall and volumetric efficiency. The report identifies the model as HPV50-MA-R-21 and includes a unique component number for traceability.

Such testing supplies product-specific operating data to application engineers and customers, beyond nominal catalogue specifications alone.

Recorded Test Data

The results captured during factory performance testing of the HPV50-MA-R-21 pump are shown below.

Conditions of the test:

• Test temperature — 31.4°C
• Rated displacement — 50 mL/rev
• Rated pressure — 35 MPa
• Max pressure — 42 MPa
