Yuken Hydraulic Pump PV2R3 & PV2R4: High-Pressure Vane Pumps Overview

1. Basic Introduction

Yuken PV2R3 and PV2R4 are part of the renowned PV2R series single vane pumps, specifically designed for low-noise operation and high-pressure performance in industrial hydraulic systems. These quantitative vane pumps are widely recognized for their reliability, efficiency, and easy maintenance, making them a popular choice across various industries worldwide.

2. Technical Specifications

Model	Displacement Range	Rated Pressure	Maximum Pressure	Speed Range
PV2R3	56-116 cm³/rev (56, 76, 94, 116 mL/r)	16 MPa	21 MPa (short time)	600-1800 rpm
PV2R4	136-237 cm³/rev (136, 153, 184, 200, 237 mL/r)	16 MPa	21 MPa (short time)	600-1800 rpm

Note: PV2R4A is a space-saving variant of PV2R4, offering similar displacement range but with a more compact design .

3. Core Features

Low Noise Operation: Adopts higher-order equation stator curve and double-lip vanes, reducing flow pulsation and keeping noise levels ≤72 dB .
High Efficiency: Optimized internal design ensures excellent volumetric efficiency and mechanical efficiency.
Robust Construction: Reinforced bearing and seal design enables continuous operation under high-pressure conditions .
Easy Maintenance: Cartridge kit structure allows for quick replacement of internal components without disassembling the entire pump .
Versatile Fluid Compatibility: Suitable for petroleum-based oils, water-glycol fluids, and synthetic hydraulic fluids .

4. Model Nomenclature (Example: PV2R3-94-L-RAA-41)

Code	Meaning
PV2R3	Series identifier (PV2R3 size)
94	Displacement (94 cm³/rev)
L	Mounting orientation (Left 45° upward - standard)
R	Rotation direction (Clockwise viewed from shaft end)
AA	Seal type (NBR standard seal)
41	Shaft type (Keyed shaft - standard)

5. Applications

PV2R3 and PV2R4 pumps are widely used in various industrial applications:

Industry	Typical Equipment	Application Scenarios
Plastic Processing	Injection molding machines, die-casting machines	Clamping, injection, ejection, mold adjustment systems
Metal Forming	Hydraulic presses, bending machines, shearing machines	Main pressure systems, slide movement, workpiece clamping
Machine Tools	CNC machines, hydraulic stations	Table movement, spindle control, tool changing mechanisms
Material Handling	Hydraulic lifts, conveyors	Lifting, tilting, positioning operations
Construction	Concrete machinery, lifting equipment	Boom movement, outrigger operation

6. Operational Considerations

Fluid Requirements: Use clean hydraulic oil with viscosity 15-400 mm²/s and cleanliness level NAS 10 or better.
Temperature Range: Optimal operating temperature is 10-60°C (maximum 80°C for short periods).
Installation: Ensure proper alignment between pump and motor shaft; use flexible coupling for connection.
Maintenance: Regularly check oil level, temperature, and pressure; replace filter elements per manufacturer's recommendations.

7. Double Pump Configurations

Yuken offers combined double pump models such as PV2R34 (PV2R3 + PV2R4), which integrate two pumps in a single housing with a common drive shaft. These provide two independent discharge ports for supplying separate hydraulic circuits, ideal for applications requiring different pressure/flow requirements in one system.

Would you like me to provide a quick comparison table of PV2R3 vs PV2R4, including typical flow rates at 1500 rpm, recommended motor power, and common replacement parts?
