YUKEN Vane Pump PV2R1-6, PV2R1-8

YUKEN PV2R1 series vane pumps are high-pressure, high-performance hydraulic pumps specifically developed for low-noise operation. Models PV2R1-6 and PV2R1-8 are small-displacement variants within the PV2R1 series, designed to meet the needs of various industrial applications, including injection moulding machines, machine tools, hydraulic presses, and other equipment that requires stable hydraulic fluid supply and reliable performance under medium to high pressure conditions.

A key feature of the PV2R1 series pumps is their integral driving parts combined into a cartridge kit. This cartridge design allows for easy and quick replacement of worn components without full disassembly of the pump, significantly reducing equipment downtime and maintenance costs. Additionally, the optimized vane and cam ring structure ensures minimal wear and long service life, even during continuous operation.

Additional Information

YUKEN PV2R1-6 and PV2R1-8 vane pumps are compatible with various hydraulic fluids, including anti-wear petroleum base oils (for maximum 21 MPa pressure), R&O petroleum base oils, water-containing fluids (water-in-oil emulsions, water glycols), and phosphate ester-based synthetic fluids. Special Viton seals are required when using phosphate ester fluids, and the model number should be prefixed with “F” when ordering.

The flow rate and power consumption of the pumps depend on the shaft speed and operating pressure; detailed data can be found in YUKEN’s official technical documentation (relevant sections for PV2R1 series). The weight of the pumps is approximately 8.0 kg for foot mounting and 9.2 kg for flange mounting, depending on the specific configuration.

To ensure reliable operation, it is important to comply with the suction conditions: the suction pressure should be in the range of -20 to +30 kPa (5.9 inches of mercury vacuum to +4.3 PSIG). The maximum allowable shaft runout must not exceed 0.1 mm TIR, and the angular misalignment must not exceed 0.2°.
