Factory Performance Testing

The LPV130-MA-R-23 is tested on a closed-loop hydraulic pump test bench. The test documentation records Component No. 02407110203001, a test on 2024/7/11 at 10:07, a test temperature of 36.8 °C and a power recovery ratio of 50%. Rated displacement is 130 mL/rev and rated pressure is 35 MPa; the test-bench main parameters are a maximum speed of 2900 r/min and a maximum pressure of 42 MPa.

Recorded Test Data

The closed-loop report logs speed, pressure, flow, displacement, torque, input power, output power, overall efficiency, volumetric efficiency and charge pressure for the LPV130-MA-R-23. Selected factory-recorded test points are provided for reference.

Charge pressure: 1.8 MPa; charge flow 34.2 L/min. Values are reproduced from the original test record and should be interpreted according to the test-bench measurement and calculation method.

Engineering Drawing & Dimensions

The supplied LPV130/160-MA-R/L-27/13-NN engineering drawing documents the mounting flange, output shaft spline, hydraulic ports, control interface and rotation direction of the LPV130-MA-R-23. Key interface information includes:

• High pressure ports A and B; leakage ports L1 / L2; oil suction port S
• High pressure relief valves A / B; low pressure relief valve
• Pressure taps Ma / Mb: 9/16-18; servo-cylinder pressure taps (both sides): 9/16-18
• Output shaft involute spline: 13 teeth, radial pitch 8/16, 30° pressure angle, Ø41.38 mm dividing circle
• Control handle spline: 1/4-20 UNC-2A, 24 teeth, diametral pitch 64/128, OD 9.5 mm (SAE 1963)
• Mounting: 4 bolts M12, 25 mm depth; ports A / B 1 5/16-12; ports L1 / L2 1 5/8-12; spacing A6 66.7 mm / A7 31.8 mm
• Charge pressure 1.8–2.4 MPa; rotation direction R (clockwise) / L (anticlockwise)

Drawing technical requirement: minimum speed 500 r/min, maximum speed 2400 r/min, rated working pressure 30 MPa. Interface dimensions should be confirmed against the engineering drawing before installation.

Quality Control & Final Inspection

Quality control of the LPV130-MA-R-23 rests on product identification, factory test documentation and engineering specifications. The test report documents the pump's displacement, pressure, speed, flow and output power recorded during closed-loop testing.
