Yuken Type PV2R Series Vane Pump | PV2R1, PV2R2, PV2R3, PV2R4 | Low Noise

Yuken Type PV2R Series High-Performance Low Noise Vane Pumps

Product Overview: The PV2R Series fixed displacement vane pumps are widely regarded as the “Silent Standard” for industrial hydraulic systems. This range encompasses a comprehensive family of frame sizes: PV2R1, PV2R2, PV2R3, and PV2R4. This featured list highlights core models including the high-flow PV2R4-237-F-RRA-30, PV2R4-237-F-LLA-30, and the versatile PV2R1-17-F-RAA-43. Utilizing a unique pressure-balanced construction and patented silencing grooves, the PV2R series maintains exceptional volumetric efficiency even under intermittent pressures up to 21 MPa—serving as the premier power core for precision machinery in modern green factories.

Key Technical Advantages:

• Ultimate Silent Technology: Specifically developed for low-noise environments. Through precision-ground vanes and optimized internal flow passages, its operational decibel level is significantly lower than conventional vane pumps, greatly enhancing the workshop environment.

• Large Displacement Coverage: The PV2R4 specification provides massive displacements up to 237 cm³/rev, delivering ample flow for heavy-duty presses while maintaining its hallmark low-noise characteristics.

• Superior Pressure Durability: Constructed with high-strength cast iron housings and specialized heat-treated internal components. It supports a rated pressure of 17.5 MPa and withstands shock loads up to 21 MPa, ensuring high reliability in harsh conditions.

• Flexible Installation: Available in Flange (F) mounting with various rotation options (Right-hand R / Left-hand L), allowing for a seamless replacement of original Yuken pumps without altering existing plumbing.

• Target Applications: Plastic injection molding machines, large die-casting machines, leather machinery, presses, hydraulic shears, and various industrial automation power units.
