TOKYO KEIKI P8VMR-10-CBC-10 Variable Piston Pump

TOKYO KEIKI TOKIMEC P8VMR-10-CBC-10 Variable Piston Pump

The TOKYO KEIKI TOKIMEC P8VMR-10-CBC-10 is a legacy compact variable displacement axial piston pump with a maximum displacement of approximately 8.4 cm³/rev.

It uses pressure-compensator control and includes a maximum-displacement adjustment feature. The pump is intended for low-noise hydraulic systems operating over an approximate pressure-setting range of 1.8 to 7 MPa.

Pressure and Displacement Control

The pressure compensator automatically reduces displacement as outlet pressure reaches the selected cutoff setting. This helps reduce energy loss when the circuit does not require full pump flow.

The additional displacement adjustment allows the maximum pump output to be limited mechanically.

Technical Specifications

Installation Notes

• Verify the drive rotation before coupling the replacement pump.
• Fill the pump case and suction line with clean hydraulic oil before startup.
• Keep the case-drain line unrestricted and directly connected to the reservoir.
• Confirm the existing maximum-displacement setting before removing the old pump.
• Check shaft dimensions, mounting pattern and port locations before shipment.

Legacy and Replacement Notes

This Design 10 model is obsolete and should be listed as old stock or on a replacement-inquiry basis. Inventory may consist of unused old stock, refurbished pumps or third-party replacements.

Some cross-reference sources identify P8VMR-20-CB-10 as a replacement. Because the replacement code does not retain the final C, confirm whether maximum-displacement adjustment is required before approving the substitution.
