PV2R1-8-F-RAA-43 | Yuken Type High Pressure Low Noise Vane Pump 8 cm³/rev

Product Overview

The PV2R1-8-F-RAA-43 is a single-stage high-pressure vane pump from the PV2R series, designed as a direct drop-in replacement for Yuken-type hydraulic pumps. Developed specifically for low-noise, high-performance applications, this pump delivers reliable hydraulic power across a broad flow range. Manufactured to strict OEM specifications, the pump features a cartridge kit modular design with internal components assembled by screws for easy maintenance and service.

As a standard model in the PV2R1 series, the PV2R1-8-F-RAA-43 offers 8 cm³/rev displacement, flange mounting (F-type), clockwise rotation viewed from the shaft end (R-type), with both discharge and suction ports oriented upward (AA-type), and design number 43. Our products achieve 100% interchangeability with original equipment in materials, machining precision, seals, and performance characteristics. Every unit undergoes 100% factory testing under simulated operating conditions to ensure reliable performance in injection molding machines, machine tools, and various industrial hydraulic systems.

Key Technical Advantages

1. Drop-in Interchangeability
Manufactured to exacting Yuken PV2R1 series OEM standards, our pump is fully interchangeable with the original PV2R1-8-F-RAA-43 in mounting dimensions, port configurations, and performance characteristics. No modifications to existing hydraulic piping or mounting brackets are required, significantly reducing downtime and retrofit costs.

2. 100% Simulated Operating Condition Testing
Every pump undergoes comprehensive factory performance testing under simulated operating conditions, covering rated pressure, peak pressure, flow characteristics, and temperature rise. This ensures the product is ready for full-load operation immediately upon installation, eliminating early failure risks.

3. Low Noise Design with High Volumetric Efficiency
The PV2R series is specifically developed for low-noise applications. Optimized vane and cam ring contact trajectories effectively reduce pressure pulsation and fluid-borne noise. Precision machining tolerances ensure exceptionally high volumetric efficiency, minimizing internal leakage and improving overall system energy efficiency.

4. Cartridge Kit Modular Construction for Easy Maintenance
The pump features a cartridge kit design with all internal components assembled as a modular unit secured by screws. Worn parts can be replaced quickly without disassembling the entire pump body, dramatically reducing service time and maintenance costs.

5. High-Quality Materials and Precision Manufacturing
Critical components are manufactured from high-grade alloy steel and wear-resistant materials, combined with high-precision CNC machining and heat treatment processes, ensuring long-term reliability and service life under high-pressure, high-speed operating conditions.

Application Areas

• Injection Molding Machines — Reliable hydraulic power source providing stable flow and pressure output

• Machine Tool Hydraulic Systems — Hydraulic power units for metal cutting machines and machining centers

• Construction Equipment — Hydraulic auxiliary systems for mini excavators, loaders, and related machinery

• Hydraulic Presses — High-pressure hydraulic power delivery

• Agricultural Machinery — Tractor hydraulic lift systems

• Industrial Automation Equipment — Hydraulic actuators for automated production lines

Expert Maintenance Tips

1. Installation Guidelines

• Verify pump rotation direction matches the drive motor (clockwise, viewed from shaft end) before installation

• Ensure coupling concentricity deviation does not exceed 0.05 mm to prevent premature bearing failure from uneven loading

• Suction line diameter should meet or exceed recommended specifications to prevent cavitation

2. Hydraulic Fluid Selection and Contamination Control

• Recommended fluids: ISO VG 32 or 46 anti-wear hydraulic oil, viscosity range 20-40 cSt (@ 40°C)

• System cleanliness should be maintained at NAS 1638 Class 9 or better; install return line filtration (≤ 10 μm absolute)

• For phosphate ester fluids, specify the F- prefix model (fluororubber seals required)

3. Start-up and Operation

• Pre-lubricate the pump by filling the drain port with clean hydraulic fluid before first start

• Perform 2-3 low-speed jogging cycles under no-load conditions to purge air from the system before applying load

• Maintain speed above 1,450 r/min when operating pressure exceeds 16 MPa

4. Scheduled Maintenance

• Replace hydraulic fluid and filters every 2,000 operating hours or annually, whichever comes first

• Regularly monitor pump housing temperature (normal temperature rise ≤ 40°C; maximum housing temperature ≤ 80°C)

• Investigate unusual noise or pressure fluctuations promptly; inspect cartridge kit components for wear

5. Spare Parts Recommendation

• Stock cartridge kit repair assemblies for quick on-site service without pump body disassembly

• Maintain seal kit inventory, especially for systems using specialty fluids such as phosphate esters
