PV2R Single Hydraulic Vane Pump

The PV2R Series is a range of high-pressure, fixed displacement vane pumps specifically designed for low-noise operation. Originally developed by Yuken, the PV2R design utilizes accurately machined vanes with curved tips to ensure smooth contact with the cam ring, significantly reducing vibration and sound levels. It is the preferred hydraulic pump for indoor industrial equipment such as injection molding machines and machine tools.

Key Features:

Series: PV2R1, PV2R2, PV2R3, PV2R4
Max. Pressure: Up to 210 bar (21 MPa)
Design: Low Noise, Cartridge Type
Application: Plastic Processing, Metal Cutting.

Product Overview The PV2R Single Vane Pump offers a perfect balance of performance and comfort. Unlike standard industrial pumps, the PV2R series features a specialized internal structure where the vanes are hydraulically balanced to minimize radial loads on the shaft bearings. This ensures exceptional durability and stable output even at pressures up to 210 bar.

Why Choose the PV2R Series?

Whisper Quiet: The unique vane geometry and optimized cam ring profile make the PV2R one of the quietest pumps available, ideal for factories with strict noise regulations.
High Efficiency: Precision manufacturing ensures high volumetric efficiency with minimal internal leakage.
Easy Maintenance: Like the V-series, the PV2R features a cartridge kit design, allowing for quick replacement of internal parts without disconnecting the pump from the piping.
Wide Range: Available in four frame sizes covering a vast range of flow requirements.

Common Applications:

Plastic Machinery: Injection Molding Machines (Main pump).
Machine Tools: CNC Lathes, Grinders.
Presses: Light to medium duty hydraulic presses.
Die Casting Machines: Hydraulic power units.
