Yuken Type PV2R Series Vane Pump | PV2R1, PV2R2, PV2R3, PV2R14 | Low Noise

Yuken Type PV2R Series High-Performance Low Noise Vane Pumps

Product Overview: The PV2R Series fixed displacement vane pumps are recognized globally as the “Low Noise Standard” for industrial hydraulic systems. This range features a comprehensive family from compact single pumps to ultra-high displacement double pump configurations, engineered to meet modern requirements for high pressure, long-term reliability, and silent operation. This featured range includes high-spec models such as the double pump S-PV2R14-25-237-L-RLAL-35, the high-flow S-PV2R3-125-L-LAR-35, and standard models PV2R1-31-L-RAA-4304 and PV2R2-59-F-RLR-41. Utilizing unique pressure-balanced construction, the PV2R series maintains exceptional volumetric efficiency even at pressures up to 21 MPa.

Key Technical Advantages:

• Ultimate Silent Operation: Patented silencing grooves significantly reduce hydraulic vibration and noise. Even at high displacements like 237 cm³/rev, these pumps maintain a quiet profile, meeting green factory standards.

• Large Displacement Double Pump Solutions: Models like the PV2R14 integrate a small cartridge and an ultra-large cartridge on a single drive shaft, powering independent high/low-pressure circuits while optimizing the installation footprint.

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

• Versatile Mounting & Orientation: Available in Flange (F) mounting with support for Left-hand (L) and Right-hand (R) rotation with various port layout combinations (e.g., RLR, RAA) for seamless replacement of original Yuken units.

• Target Applications: Large-scale injection molding machines, scrap balers, leather machinery, heavy-duty presses, and automated power systems.
