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

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

The TOKYO KEIKI TOKIMEC P8VMR-10-CB-10 is a legacy low-noise variable displacement axial piston pump with an approximate maximum displacement of 8.4 cm³/rev.

The CB configuration uses pressure-compensator control without the additional maximum-displacement adjuster identified by a final C in the CBC version.

Pressure Compensator Function

The compensator reduces pump displacement when delivery pressure reaches the selected setting. This allows pressure to be maintained while reducing unnecessary pump delivery.

The approximate pressure-setting range is 1.8 to 7 MPa. The exact setting must be verified during commissioning with a calibrated pressure gauge.

Technical Specifications

Installation Notes

• Check motor rotation before installing the coupling.
• Prime the pump and fill the case before starting the hydraulic power unit.
• Keep the suction line short, adequately sized and airtight.
• Return the case drain directly to the tank.
• Confirm the original pressure setting before removing the existing pump.

Legacy and Replacement Notes

This Design 10 pump is obsolete and should be offered as old stock or on a replacement-inquiry basis. Confirm whether the offered unit is unused old stock, refurbished or a compatible replacement.

P8VMR-20-CBC-10 is cited as a replacement candidate by some suppliers, but the additional C indicates a different displacement-adjustment configuration. Confirm interchangeability before shipment.
