YUKEN Double vane pump PV2R12、PV2R13
YUKEN PV2R series double vane pumps are well-recognized for their high pressure resistance, stable efficiency, and low-noise operation, and the PV2R12 and PV2R13 models are medium-displacement variants tailored for industrial hydraulic systems. As double vane pumps.
they feature a dual-vane structure that ensures balanced radial hydraulic forces on the rotor shaft, enhancing operational stability and service life compared to single vane pumps. These pumps are widely applied in medium-sized injection moulding machines, hydraulic punching machines, textile machinery, and other equipment that requires steady hydraulic fluid supply, reliable load-bearing capacity, and long-term operation under medium to high pressure conditions.
Consistent with the core design concept of the PV2R series, the PV2R12 and PV2R13 double vane pumps adopt integral driving components integrated into a cartridge kit. This cartridge structure allows for quick and convenient replacement of worn parts without full disassembly of the entire pump, which significantly reduces equipment downtime and maintenance costs.
In addition, the optimized double-vane and cam ring structure—with the rotor and stator arranged concentrically—enhances wear resistance and sealing performance, while the dual-vane design prevents excessive radial force, ensuring stable operation even in harsh industrial environments with continuous high-load work. A triangular groove is also designed on the pressure oil window to avoid oil trapping, further improving operational reliability.

Additional Information
YUKEN PV2R12 and PV2R13 double 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. As quantitative double vane pumps with a concentric rotor-stator structure, they deliver stable flow output, making them suitable for equipment requiring consistent hydraulic supply. When using phosphate ester fluids, special Viton seals are required, and the model number should be prefixed with “F” when ordering.
The flow rate and power consumption of the double vane pumps vary with shaft speed and operating pressure; detailed data can be found in YUKEN’s official technical documentation (relevant sections for the PV2R series). The weight of the pumps is approximately 10.5–12.0 kg for PV2R12 and 11.0–12.5 kg for PV2R13, depending on the mounting type and specific configuration. Their compact structure, combined with the double-vane design, also contributes to space-saving installation and easy integration into existing hydraulic systems.
To ensure reliable and long-term operation, it is crucial 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°. Regular maintenance and inspection of the cartridge components are also recommended to extend the pump’s service life.
