PV2R12-14-47-F-RAA-40 Yuken Double Vane Pump 210 bar

Product Overview

The PV2R Series, manufactured by Yuken, is a renowned high-pressure fixed displacement vane pump family, specially developed for low-noise operation. PV2R Series single pumps provide a wide delivery volume range of 5.8–237 cm³/rev, while double pumps consist of two PV2R series single pumps combined in tandem within a single housing and driven by a common shaft. The double pumps feature a single suction port and two discharge ports, allowing output flow to be supplied to separate circuits.

PV2R Series double pumps encompass PV2R12, PV2R13, PV2R14, PV2R23, PV2R24, and PV2R34 combinations, adapting to small-to-large multi-circuit hydraulic system requirements. PV2R12 combines PV2R1 + PV2R2, PV2R13 combines PV2R1 + PV2R3, PV2R14 combines PV2R1 + PV2R4, PV2R23 combines PV2R2 + PV2R3, PV2R24 combines PV2R2 + PV2R4, and PV2R34 combines PV2R3 + PV2R4.

The PV2R Series features a high-order equation stator curve design, significantly reducing noise compared to traditional vane pumps. The main internal components employ a cartridge kit structure, facilitating easy maintenance and quick replacement. The series offers high pressure (up to 210 bar / 21 MPa) , high volumetric efficiency (≥98%) , low noise, and long service life.

Our products are manufactured to be 100% interchangeable with Yuken original specifications—a true “drop-in” replacement solution. Every unit undergoes 100% full-load and flow-matching testing under simulated operating conditions before shipment, ensuring volumetric efficiency, flow rate, and noise performance meet or exceed original specifications at rated pressure.

Key Technical Advantages

1. High-Order Equation Stator Curve – Ultra-Low Noise Operation
The PV2R Series employs a high-order equation stator curve design, effectively reducing impact and friction between vanes and the stator. Operating noise is significantly reduced compared to traditional vane pumps. The series is specially developed for low-noise operation, making it an ideal choice for noise-sensitive applications such as injection molding machines.

2. Cartridge Structure – Easy Maintenance
The PV2R Series features a cartridge kit structure, with all internal components assembled as an integral unit using screws. Pump cartridges can be replaced quickly without removing the entire pump from the system, dramatically reducing downtime and maintenance costs.

3. High Pressure Capability in a Compact Envelope
The PV2R Series achieves operating pressures up to 210 bar (21 MPa) within a compact housing size. High-pressure capability allows the use of smaller actuators and lines, reducing overall system cost and installation footprint. Volumetric efficiency exceeds 98%.

4. Double Pump Design – Single Power Source, Dual Circuits
PV2R Series double pumps combine two single pumps in tandem within a single housing, driven by a common shaft. A single suction port and two discharge ports are provided, allowing output flow to be supplied to separate circuits. This design enables more compact system layout, reducing installation space and cost.

5. Wide Displacement Range for Flexible Adaptation
PV2R Series double pumps offer extensive displacement combination options. PV2R12 Series: small side 6–31 ml/r, large side 26–65 ml/r; PV2R13 Series: small side 6–31 ml/r, large side 52–153 ml/r; PV2R23 Series: small side 26–75 ml/r, large side 52–153 ml/r. Users can flexibly select the optimal combination based on system flow requirements.

6. Broad Fluid Compatibility
The PV2R Series is compatible with petroleum-based oils, anti-wear oils, water glycols, water-in-oil emulsions, and phosphate esters. Flexible fluid selection based on actual operating conditions.

7. 100% Drop-In Interchangeability – Zero Retrofit Cost
Manufactured to exact Yuken original specifications—mounting dimensions, port locations, and shaft configurations are identical to the original. Mounting flange dimensions comply with international standards. No piping modifications or installation adapters are required for direct replacement.

Expert Maintenance Tips

1. Model Identification and Selection

• PV2R12 Series: Small side PV2R1 (6–31 ml/r) + Large side PV2R2 (26–75 ml/r)

• PV2R13 Series: Small side PV2R1 (6–31 ml/r) + Large side PV2R3 (52–153 ml/r)

• PV2R14 Series: Small side PV2R1 (6–31 ml/r) + Large side PV2R4 (136–200 ml/r)

• PV2R23 Series: Small side PV2R2 (26–75 ml/r) + Large side PV2R3 (52–153 ml/r)

• Model Code Interpretation: Taking PV2R12-14-47-F-RAA-40 as an example—PV2R12 = Series combination (PV2R1+PV2R2), 14 = Small pump displacement code (14 ml/r), 47 = Large pump displacement code (47.2 ml/r), F = Flange mounting, R = Clockwise rotation, AA = Discharge port position (upwards), 40 = Design number.

2. Installation Precautions

• Verify pump rotation direction matches system requirements—R denotes clockwise, L denotes counter-clockwise (viewed from shaft end).

• Confirm mounting type matches—F is flange mounting, L is foot/base mounting.

• Suction piping should be as short as possible, minimizing unnecessary restrictions.

• The pump housing must not bear piping loads; suction and discharge lines must have independent supports.

• PV2R12 double pump net weight is approx. 25 kg (flange mount)—ensure support structure is sufficiently robust.

3. Pre-Startup Checklist

• Verify oil level in the reservoir is adequate and fluid type is correct (ISO VG32, VG46, or VG68 anti-wear hydraulic oil recommended).

• Confirm all piping connections are secure with no leakage.

• Prime the pump by filling the housing with oil before first startup to prevent dry running.

• Confirm both discharge ports are correctly connected to their respective hydraulic circuits.

4. Fluid Management

• PV2R Series is compatible with petroleum-based oils, anti-wear oils, water glycols, water-in-oil emulsions, and phosphate esters.

• Petroleum-based oils: rated 160 bar (max 210 bar); water glycol fluids: rated 160 bar.

• Fluid cleanliness should be maintained at NAS 9 or higher—contamination is the leading cause of premature vane pump failure.

• Regularly check oil temperature to ensure it does not exceed 60°C.

5. Scheduled Maintenance

• Replace hydraulic oil and filters every 2000 operating hours or annually.

• PV2R Series features cartridge-type construction—cartridges can be replaced independently.

• Cartridge replacement can be completed in minutes without removing the entire pump.

• If flow drops or pressure becomes unstable, first inspect cartridge wear—replacing the cartridge kit restores performance.
