Evidence type: factory production / product identification.

Factory Performance Testing

Factory performance testing of the LPV30-MA-R-21 is carried out on a closed-loop hydraulic pump test bench. The test documentation records Component No. 02603270203001, a test on 2026/3/27 at 10:11, a test temperature of 36.2 °C and a power recovery ratio of 20%. Rated displacement is 30 mL/rev and rated pressure is 35 MPa; the test-bench main parameters are a maximum speed of 3800 r/min and a maximum pressure of 42 MPa.

Recorded Test Data

For the LPV30-MA-R-21, the closed-loop report logs speed, pressure, flow, displacement, torque, input power, output power, overall efficiency, volumetric efficiency and charge pressure. Selected recorded points are shown for reference.

Charge pressure: 1.4 MPa; charge flow 10.3 L/min. Figures are reproduced from the original test record; interpretation should follow the test-bench measurement and calculation method.
