Supporting the project documentation are product technical parameters, engineering drawings and a factory performance test report for the HPV50-MA-R-21.

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

Factory Performance Testing

To confirm key operating characteristics under controlled conditions, the HPV50-MA-R-21 closed-loop axial piston pump is performance-tested before it leaves the factory.

For the tested pump, the factory test took place on 14 September 2026 at a test temperature of 31.4°C. Rated displacement was 50 mL/rev, rated pressure 35 MPa and maximum pressure 42 MPa.

The recorded procedure covered pump speed, outlet pressure, flow rate, displacement, input torque, input power, output power, overall efficiency and volumetric efficiency. A unique component number and the component model HPV50-MA-R-21 are stated in the report for traceability.

Factory performance testing therefore provides application engineers and customers with product-specific operating data, rather than relying only on nominal catalogue specifications.

Recorded Test Data

The following data were recorded during factory performance testing of the HPV50-MA-R-21 hydraulic pump.

Test conditions:

• Test temperature: 31.4°C
• Rated displacement: 50 mL/rev
• Rated pressure: 35 MPa
• Maximum pressure: 42 MPa
• Maximum speed: 3500 r/min
• Charge pressure: 1.6 MPa
• Charge flow: 12.4 L/min

The recorded values are from the factory test report for HPV50-MA-R-21, component No. 02609140203023.

Engineering Drawing

Engineering drawings with full dimensions are supplied for the HPV50-MA-R-21 closed-loop axial piston pump.

They provide the dimensional and interface information necessary for system integration: overall mounting dimensions, shaft and spline specifications, hydraulic ports, leakage ports, pressure test ports, control-handle dimensions and control positions.

The drawings additionally specify the rotation direction and the pressure-port configuration for both clockwise and counterclockwise operation.

Key interface data include:

• HPV50-MA-R-21 product model
• 50 mL/rev rated displacement
• Ports A and B (main)
• Ports L1 and L2 (leakage)
• Port S (oil suction)
• Port M (pressure/test)
• Control: Manual / EP servo / Hydraulic servo
• Input shaft spline configuration by model
• SAE-related control and shaft dimensions

Hydraulic system designers can use these drawings to check mounting, shaft connection, port configuration and installation requirements before ordering.

Quality Control & Inspection

Before shipment, quality control of the HPV50-MA-R-21 covers product configuration, dimensional requirements and hydraulic performance.

The factory test record for the tested unit states the manufacturer, component model, component number, rated displacement, rated pressure, maximum pressure and test temperature; performance inspection covers operating speed, pressure, flow, displacement, input torque, input power, output power, overall efficiency and volumetric efficiency.

Dimensional and interface information for the pump body, hydraulic ports, leakage ports, shaft spline and control mechanism is provided in the engineering documentation.

Together, the configuration records, engineering documentation and recorded performance data give traceable technical evidence for the hydraulic pump supplied.
