Factory Performance Testing

The HPV70-MA-R-21 comes with a documented closed-loop hydraulic pump performance test record.

The supplied report lists the component as HPV70-MA-R-21, rated 70 mL/rev, and dates the test to September 14, 2026 at 26.8°C.

Measured parameters include speed, pressure, flow, displacement, torque, input and output power, overall efficiency and volumetric efficiency, spanning pressures of about 5 MPa to 30.6 MPa.

Recorded Test Data

The table below lists performance values taken from the supplied closed-loop hydraulic pump test report for HPV70-MA-R-21.

Test Conditions

• Test Date: September 14, 2026
• Test Temperature: 26.8°C
• Rated Displacement: 70 mL/rev
• Rated Pressure: 35 MPa
• Maximum Pressure: 42 MPa
• Charge Pressure: 1.6 MPa
• Charge Flow: 21.9 L/min

The data above reflects the documented factory test conditions; actual operating results may vary with hydraulic circuit configuration, fluid conditions, temperature and application conditions.

Engineering Drawing

HPV70 Engineering Drawing & Technical Documentation

The HPV70-MA-R-21 is backed by engineering documentation covering dimensional integration and hydraulic configuration.

From the supplied engineering drawing, the control handle, maximum and zero displacement positions, hydraulic ports, leakage ports, oil suction port and pressure test point are identified, along with the shaft spline and control-handle information required for mechanical integration.

Engineering Information Covered

• Overall mounting and dimensional information
• Control handle geometry
• Maximum displacement position
• Zero displacement position
• High-pressure ports A and B
• Leakage ports L1 and L2
• Oil suction port S
• Pressure test port M
• Servo cylinder pressure test point
• Input shaft spline configuration
• Control-handle spline information
• Pump rotation direction
• Control configuration information

The same drawing records the MA, EP and HS control configurations for the HPV series and identifies both clockwise and counterclockwise rotation options.

Engineering Integration

Before system integration, the selected displacement, control method, rotation direction, shaft configuration and hydraulic port arrangement should be checked against the applicable engineering drawing and application requirements.
