PV2R1-14-F-RAA-43 Yuken Vane Pump 16 MPa

Product Overview

The PV2R1-14-F-RAA-43 is a Yuken PV2R Series fixed displacement single vane pump designed for high-pressure industrial hydraulic systems where stable displacement, low-noise operation and dependable mechanical integration are required.

Yuken’s official documentation describes the PV2R family as high-pressure, high-performance vane pumps developed especially for low-noise operation. The series covers multiple frame sizes including PV2R1, PV2R2, PV2R3 and PV2R4, with official catalogs, structural drawings, CAD data and instruction manuals available from Yuken.

For the PV2R1-14, the actual geometric displacement is 13.7 cm³/rev, rather than exactly 14.0 cm³/rev. In the full model code, F identifies the flange-mounted configuration, while the Yuken coding system also uses the F option for special seals intended for phosphate-ester hydraulic fluids. The complete model code should therefore be verified before replacement.

The R suffix specifies standard clockwise rotation when viewed from the shaft end. Both A codes identify the standard upward port arrangement, and 43 is the applicable design number.

For aftermarket replacement, the correct engineering approach is to match the complete configuration—including displacement, mounting, rotation, port orientation, shaft arrangement and design number. Our replacement units can additionally undergo 100% simulated operating-condition testing before shipment to verify pressure build-up, flow stability, leakage condition and operating behavior.

Engineering Note

The “14” in the model designation represents the displacement size designation, while the manufacturer’s published geometric displacement is 13.7 cm³/rev. Flow and motor-power calculations should therefore use the published geometric displacement rather than assuming 14.0 cm³/rev.

Key Technical Advantages

1. High-Pressure Fixed-Displacement Architecture

The PV2R1 is a fixed displacement vane pump developed for high-pressure and high-performance hydraulic applications. Its fixed displacement architecture provides a straightforward pump source for systems that do not require variable flow compensation or electronic displacement control.

2. Precisely Defined 13.7 cm³/rev Displacement

The PV2R1-14 provides a published geometric displacement of 13.7 cm³/rev. The theoretical flow can therefore be established from displacement and rotational speed, while actual flow must also account for pressure, viscosity and volumetric efficiency.

3. Low-Noise Hydraulic Architecture

Yuken specifically developed the PV2R series for low-noise operation. The vane-pump architecture provides comparatively smooth displacement behavior, which can help reduce hydraulic pulsation when the pump is correctly installed and operated within its specified conditions.

4. Flange Mounting for Industrial Integration

The F configuration uses flange mounting, with PV2R1 mounting dimensions based on the SAE 4-bolt split flange, standard-pressure dimensional system. This type of interface is particularly useful for industrial hydraulic power units and rigid high-pressure piping arrangements.

5. Full Model Coding Supports Accurate Retrofit

The complete PV2R1-14-F-RAA-43 code conveys important engineering configuration information:

• PV2R1 = pump series
• 14 = displacement size
• F = flange mounting / special-seal option position in the coding system
• R = clockwise rotation
• A = standard upward discharge port
• A = standard upward suction port
• 43 = design number

Matching the complete model code is therefore much safer for machine retrofit work than matching the basic PV2R1-14 designation alone.

6. Cartridge-Type Driving Components

Yuken states that the integral driving parts of PV2R pumps are arranged as a cartridge kit and are available separately. This architecture can simplify service work by allowing the driving components to be replaced without treating the complete pump as a single non-serviceable assembly.

Application Areas

The Yuken PV2R family is designed for a broad range of industrial hydraulic applications, including:

• Injection molding machines
• Die-casting machines
• Machine tools
• Industrial hydraulic machinery
• Hydraulic power units
• Automated production equipment
• Hydraulic clamping systems
• Metalworking machinery
• Selected construction and mining auxiliary hydraulic systems, subject to pressure, flow, fluid and mounting requirements

Yuken’s official documentation specifically identifies injection moulding machines, die casting machines, machine tools and hydraulic machinery as applications. For mining and heavy-duty equipment, final suitability should be verified against the actual hydraulic circuit rather than selected solely by machine category.

Expert Maintenance Tips

1. Verify Hydraulic Fluid Compatibility

Because this configuration includes the phosphate-ester seal option, the actual hydraulic fluid must be confirmed before operation. For phosphate-ester fluids, the published maximum operating pressure is 16 MPa, and maximum speed is limited to 1200 r/min. The 21 MPa / 1800 r/min mineral-oil values should not be applied without checking the fluid configuration.

2. Confirm Rotation Before Commissioning

The R code specifies clockwise rotation viewed from the shaft end. Confirm the prime mover rotation before startup to prevent improper operation.

3. Protect the Suction Circuit

Yuken’s installation guidance emphasizes appropriate suction pressure, pipe diameter and installation height. When a pump is installed above the tank, the suction-port height must remain within the specified limits to reduce starting problems and cavitation risk. Air-bleeding measures may also be required after long periods of shutdown.

4. Maintain Hydraulic Cleanliness

Yuken recommends controlling hydraulic-fluid contamination to NAS Class 12 and using a 100 µm (150-mesh) tank filter on the suction side. Contaminated fluid can accelerate wear and reduce pump service life.

5. Maintain Accurate Shaft Alignment

Yuken recommends using a flexible coupling whenever possible and avoiding bending and thrust loads. The published installation limits are less than 0.1 mm TIR for permissible misalignment and less than 0.2° for permissible misangularity. Proper alignment is important for protecting the shaft, bearings and coupling.

6. Check Viscosity During Low-Speed Startup

Yuken specifies that the maximum permissible fluid viscosity can be restricted during low-speed startup. This is especially important after extended shutdowns, in low ambient temperatures or when high-viscosity hydraulic fluids are used.
