YUKEN PV2R1 Series Fixed Low-Noise Vane Pumps
Product Introduction
PV2R1 is a classic single-stage fixed low-noise vane pump manufactured by Japan YUKEN. It is widely used as auxiliary pumps for engineering machinery, lubrication pumps, small hydraulic stations and machine tools. It adopts a dedicated low-noise stator profile with small pressure pulsation and stable operation. It features a modular cartridge design; only the pump cartridge needs replacement for maintenance to cut service costs.

Operation Notes
- Use anti-wear hydraulic oil with cleanliness ≥ NAS 8 grade. Recommended VG46 anti-wear hydraulic oil.
- Keep suction pipeline short and reduce elbows to avoid cavitation, otherwise noise rises and vanes/stator wear rapidly.
- Standard rotation R (clockwise viewed from shaft end). Confirm motor rotation before purchase.
- Original YUKEN and domestic replacement versions available in market. Check flange, shaft diameter, port position and displacement for replacement.
- Modular pump cartridge structure. Replace cartridge directly without full pump disassembly for maintenance.
Application
Pilot oil supply for construction machinery, brake auxiliary pump, lubrication auxiliary pump; small hydraulic stations, machine tools, injection molding machines, die casting machines, rubber machinery. Advantage over gear pumps: low noise and small pressure pulsation for smooth running.
