PV2R1-10-F-RAA-43 Yuken Vane Pump 9.4 cm³/rev

Product Overview

The PV2R1-10-F-RAA-43 is a Yuken PV2R Series single fixed-displacement vane pump developed for high-pressure industrial hydraulic systems requiring stable flow, low-noise operation and reliable mechanical integration.

Yuken describes the PV2R family as high-pressure, high-performance vane pumps developed especially for low-noise operation. The series includes PV2R1, PV2R2, PV2R3 and PV2R4 frame sizes and is designed for a wide range of industrial hydraulic applications, including injection molding equipment.

For the primary model PV2R1-10-F-RAA-43, Yuken specifies a geometric displacement of 9.4 cm³/rev. The PV2R1 family also includes 12.2, 13.7, 16.6, 18.6 and 22.7 cm³/rev versions corresponding to PV2R1-12, PV2R1-14, PV2R1-17, PV2R1-19 and PV2R1-23.

The complete model code provides important engineering information:

• PV2R1: Series
• 10: Displacement size
• F: Flange mounting
• R: Clockwise rotation, viewed from shaft end
• A: Discharge port upward
• A: Suction port upward
• 43: Design number

Yuken also states that when phosphate ester hydraulic fluid is used, an F- prefix must be added to the complete model number because special fluororubber seals are required. Therefore, the F within PV2R1-10-F-RAA-43 identifies the mounting configuration; it is not itself the phosphate-ester prefix.

For replacement applications, the pump should be matched by displacement, mounting configuration, rotation, port orientation and design number. Our replacement units can additionally undergo 100% simulated operating-condition testing before shipment to verify pressure build-up, operating stability, abnormal noise and leakage condition.

Engineering Note: The numbers 10, 12, 14, 17 and 19 are displacement designations within the model coding system. The manufacturer’s actual geometric displacements are 9.4, 12.2, 13.7, 16.6 and 18.6 cm³/rev, respectively. Use these published values for engineering calculations rather than assuming the nominal number is the exact displacement.

Key Technical Advantages

1. High-Pressure Fixed-Displacement Architecture

Yuken specifies the PV2R as a high-pressure, high-performance vane pump. Under the applicable anti-wear petroleum-oil condition, PV2R1 can reach a maximum operating pressure of 21 MPa. For hydraulic circuits that do not require variable displacement control, the fixed-displacement configuration provides a straightforward and predictable hydraulic power source.

2. Low-Noise Hydraulic Design

The PV2R family was specifically developed for low-noise operation. Yuken publishes noise characteristics for PV2R1 under defined test conditions, including a fluid viscosity of 20 mm²/s and a measurement position one meter horizontally from the pump.

From a system-engineering perspective, the vane-pump architecture can provide comparatively smooth flow behavior, helping control pump-generated pressure pulsation and vibration when suction conditions, piping and coupling alignment are properly managed.

3. Flange-Mounted Industrial Configuration

The F mounting configuration uses a flange connection, making the pump suitable for rigid industrial piping and hydraulic power-unit layouts. Yuken also provides dedicated pipe flange kit information for the PV2R series.

4. Complete Model Code Enables Accurate Retrofit Matching

The complete PV2R1-10-F-RAA-43 designation defines more than displacement. It identifies:

Series + displacement + mounting + rotation + discharge-port position + suction-port position + design number.

For replacement engineering, matching the complete model code is therefore more reliable than matching only the PV2R1-10 designation. Yuken’s official documentation lists PV2R1-10-*-RAA-43 among the applicable 43-design models.

5. Cartridge-Based Service Concept

Yuken states that the integral driving components of the PV2R pumps are assembled as a cartridge kit and can be supplied separately. This can simplify service operations and reduce downtime compared with replacing an entire pump assembly in every maintenance event.

6. Clearly Defined Fluid-Specific Operating Limits

The PV2R specifications differentiate pressure and speed limits according to hydraulic-fluid type. The 21 MPa / 1800 r/min figures are not universal limits for every fluid configuration.

For example, phosphate-ester and water-containing fluids have a maximum speed of 1200 r/min, and several fluid categories have lower maximum pressure ratings. Correct fluid identification and seal selection are therefore essential for long-term reliability.

Application Areas

Yuken identifies PV2R pumps for various industrial hydraulic applications, including injection molding machines and general hydraulic machinery.

Typical applications include:

• Injection molding machines
• Die-casting machines
• Machine tools
• Metalworking equipment
• Industrial hydraulic power units
• Automated production machinery
• Hydraulic clamping systems
• Forming machinery
• General industrial hydraulic systems
• Selected engineering and mining auxiliary hydraulic circuits

For mining and heavy-duty machinery, final suitability should be checked against actual continuous pressure, peak loads, operating speed, hydraulic fluid, pump mounting and available installation space rather than selected only by equipment category.

Expert Maintenance Tips

1. Verify the Complete Model Code

Before installation, confirm:

PV2R1-10 + F + R + A + A + 43

Rotation and port orientation are particularly important because a mismatch can require piping modification or prevent normal commissioning.

2. Correctly Identify the Phosphate-Ester Version

Yuken requires the F- prefix before the complete model number when phosphate-ester fluid is used because special fluororubber seals are required.

Therefore:

Standard: PV2R1-10-F-RAA-43

Phosphate Ester Configuration: F-PV2R1-10-F-RAA-43

3. Observe the High-Pressure Speed Requirement

Yuken notes that for operating pressures above 16 MPa, the pump speed should be increased above 1450 r/min. Therefore, operation close to the 21 MPa rating should not be designed around low-speed operation.

4. Protect the Suction Circuit

Avoid unnecessary restrictions, excessive bends and undersized suction piping. Proper inlet conditions help reduce aeration, unstable flow and cavitation-related damage.

5. Maintain Hydraulic Cleanliness

Vane pumps depend on controlled internal clearances and sliding contact surfaces. Good filtration and regular inspection of the hydraulic fluid are therefore essential for limiting abrasive wear and maintaining volumetric performance.

6. Maintain Proper Shaft Alignment

Flange mounting does not eliminate the need for accurate shaft alignment. Excessive angular or parallel misalignment, incorrect coupling installation or coupling preload can increase bearing and shaft-seal loading and shorten pump service life.
