HP-B 90KW Hydraulic Pump Test Bench Motor Repair Stand

The HP-B 90KW hydraulic comprehensive test bench is a standard workshop configuration designed for rebuilding hydraulic pumps and motors in service centers, OEM workshops, and dealer service facilities. The 90KW drive motor delivers full-load test capability for most open and closed circuit piston pumps used in construction machinery, agricultural equipment, injection molding machines, and industrial hydraulic systems up to 35 MPa system pressure.

The HP-B 90KW configuration supports rebuilding of Rexroth A10VSO / A4VG / A11VO axial piston pumps, Parker P1/P2/PV series, Kawasaki K3V / K5V / K7V series, Vickers V/VQ series, Denison T6 / T7 vane pumps, and commercial gear pumps from Bosch, Marzocchi, and Casappa. The bench includes a 22KW auxiliary motor for low-pressure oil supply plus a high-pressure loading circuit driven by the 90KW main motor.

Application coverage includes Caterpillar excavator main pumps, Komatsu wheel loader hydraulic systems, Hitachi mining shovel pumps, Volvo construction equipment hydraulic circuits, Manitowoc and Tadano crane hydraulic systems, agricultural tractor hydraulic pumps from John Deere and Case IH, injection molding machine hydraulic systems from Haitian and Borche, and steel mill hydraulic systems. The bench supports 0-1500 RPM variable speed control with manual bidirectional loading.

The HP-B 90KW bench is supplied with multilingual installation manual covering setup, hydraulic connection, electrical wiring, software calibration, and maintenance procedures. The 1300L oil reservoir with GB/T14039 19/16 cleanliness meets ISO 16/14/11 NAS 10 specifications. Optional accessories include test curve software, printer, and 40MPa pressure upgrade for systems requiring higher test pressure.

1. Standard Workshop Configuration - The HP-B 90KW is the factory default 90KW hydraulic test bench configuration, balancing test capability for most open and closed circuit piston pumps against practical workshop power consumption and operating cost.

2. Broad Pump Coverage - The 90KW configuration rebuilds Rexroth A10VSO / A4VG / A11VO axial piston pumps, Parker P1/P2/PV series, Kawasaki K3V / K5V / K7V series, Vickers V/VQ, Denison T6 / T7 vane pumps, plus Bosch Marzocchi and Casappa gear pumps.

3. 35 MPa System Pressure - Standard 35 MPa hydraulic test pressure suitable for excavator main pumps, wheel loader hydraulic systems, injection molding machine hydraulic circuits, and most construction equipment hydraulic pumps up to 35 MPa rated pressure.

4. Variable Speed Drive - 0-1500 RPM variable speed control driven by 90KW main motor plus 22KW auxiliary motor for low-pressure oil supply, with manual bidirectional loading for forward and reverse pump testing.

5. 1300L Oil Reservoir - Large 1300L oil reservoir (1000L actual fill) with GB/T14039 19/16 cleanliness meeting ISO 16/14/11 NAS 10 specifications, suitable for high-viscosity hydraulic oil testing.

6. Worldwide Service - BEACON MACHINE ships the HP-B 90KW globally with multilingual installation manual, hydraulic connection diagrams, electrical wiring schematics, and remote commissioning support for service centers and OEM workshops.
