Yuken PV2R1 Single Vane Pump

The Yuken PV2R Series is a high-pressure, ultra-low-noise single vane pump developed specifically for demanding industrial applications. The PV2R1-8-F-RAA-40 model delivers a displacement of 8 cm³/rev and can operate continuously at pressures up to 21 MPa (210 bar). Featuring Yuken’s proprietary internal design and precision machining, this pump offers exceptionally quiet operation, making it the preferred choice for indoor factory environments, particularly in plastic injection molding machines and precision machine tools.

Key Features:

Brand: Yuken (Japan)
Series: PV2R1 (Single Vane Pump)
Displacement: 8 cm³/rev
Max. Pressure: 21 MPa (210 bar)
Design Feature: Ultra-low noise and easily replaceable cartridge kit.

Product Overview The Yuken PV2R1 single vane pump combines high performance with a compact footprint. Unlike traditional gear pumps, the PV2R series utilizes a balanced vane design that minimizes radial loads on the shaft and bearings, resulting in a significantly longer service life and higher pressure capabilities.

Why Choose the Yuken PV2R Series?

Whisper-Quiet Operation: The precisely engineered cam ring and optimized porting drastically reduce pressure pulsations and mechanical noise, ensuring compliance with strict industrial workplace noise regulations.
Cartridge Kit Design: The internal pumping elements (cam ring, rotor, vanes, and side plates) are housed in a single “cartridge.” This means you can completely rebuild the pump in minutes by simply swapping the cartridge kit, without disconnecting the pump housing from the motor or hydraulic lines.
High Reliability: Excellent suction characteristics and wear-resistant materials ensure stable performance even under continuous high-load operations.
Wide Range of Displacements: The PV2R family covers a massive range of flow requirements, from small 6cc units to massive 237cc units (PV2R4).

Common Applications:

Plastic Machinery: Injection molding machines, blow molding machines.
Machine Tools: CNC lathes, machining centers, hydraulic presses.
Industrial Equipment: Compact hydraulic power units (HPUs), compactor machines, and material handling equipment.
