Economical Hydraulic Vane Pump PV2R3-153
3 month ago
Product details
The Yuken PV2R3-153 is the 152.8 mL/rev model in the PV2R3 low-noise, high-pressure vane pump series. Key specifications: Max. pressure: 17.5 MPa; Max. speed: 1200 rpm.
Addressing critical noise-pressure challenges in industrial hydraulics, the PV2R series represents a breakthrough vane pump platform with cross-border R&D integration. Its patent-pending rotor-stator geometry enables:
17.5MPa continuous operation at 65dB
<2% flow ripple at 1500rpm
Mineral/ester fluid compatibility (-25°C to 90°C)
Standardized flange configurations ensure direct replacement in CNC machining centers, extruders, forging hammers, compact loaders, and automated guided vehicles.
I. Product Model Breakdown: PV2R3-153
• PV: Yuken vane pump series code, indicating a variable displacement vane pump (adjustable flow rate).
• 2R: Dual-pump identifier, signifying two independent pump bodies in tandem for simultaneous output of two different flow rates or pressures.
• 3: Displacement grade, typically corresponding to a single-pump displacement of 3 mL/rev (subject to Yuken’s official specifications).
• 153: Model sub-identifier, potentially representing total displacement (e.g., 153 mL/rev for dual pumps) or pressure rating/port size (verify with product manual).
II. Core Performance Specifications
1. Basic Specifications
• Displacement Range:
• Single pump: 3 mL/rev (PV2R3 segment)
• Dual-pump total: 153 mL/rev (PV2R3-153 overall, subject to verification)
• Rated Pressure:
• Continuous operating pressure: 21 MPa (3,000 psi)
• Peak pressure: 25 MPa (3,600 psi)
• Speed Range: 600–1,800 rpm, adaptable to diverse operating conditions.
• Flow Rate Range:
• Single pump: 1.8–5.4 L/min (calculated as 3 mL/rev × 600–1,800 rpm)
• Dual-pump total: 91.8–275.4 L/min (153 mL/rev × 600–1,800 rpm, confirm displacement definition)
2. Efficiency Metrics
• Volumetric Efficiency: ≥90% (under ISO standard test conditions)
• Total Efficiency: ≥82%, delivering significant energy savings.
• Pressure Pulsation: ≤±1.5%, ensuring smooth operation.
III. Structural and Design Advantages
1. Dual-Pump Integrated Design
• Independent Circuits: Two pump bodies can drive separate actuators (e.g., hydraulic cylinders, motors) for synchronous or asynchronous control.
• Compact Layout: Short axial length reduces installation space, ideal for multi-circuit hydraulic systems.
2. Vane and Stator Technology
• High-Wear-Resistant Vanes: Alloy steel vanes and optimized stator curves minimize leakage and extend service life.
• Variable Displacement: Some models support pressure compensation or flow regulation to adapt to load variations.
3. Sealing and Reliability
• Dual Sealing: Shaft ends feature composite seals (lip seal + O-ring) to prevent leaks.
• Bearing Design: High-strength roller bearings withstand radial and axial loads, offering a lifespan exceeding 10,000 hours.
IV. Economic Analysis
1. Cost Advantages
• Cost-Effectiveness: Lower pricing compared to imported high-end pumps, with maintenance costs reduced by 30%–50%.
• Energy Efficiency: Total efficiency ≥82% reduces energy consumption by 15%–20% over long-term operation.
2. Applicable Scenarios
• Medium-High Pressure, Large Flow Systems: Injection molding machines, die-casting machines, and industrial hydraulic power sources.
• Dual-Circuit Synchronous Control: Applications requiring simultaneous actuation of multiple components (e.g., excavators, cranes).
V. Typical Application Fields
1. Industrial Hydraulics: Injection molding machines, die-casting machines, and machine tool spindle drives.
2. Construction Machinery: Hydraulic systems for excavators, loaders, and cranes with multi-action coordination.
3. Marine and Offshore Engineering: Steering gears and deck machinery with dual-circuit hydraulic drives.
4. Energy Sector: Wind turbine pitch control systems and gas turbine hydraulic controls.
VI. Selection and Alternative Recommendations
1. Selection Criteria
• System Pressure: Ensure operating pressure ≤21 MPa and peak pressure ≤25 MPa.
• Flow Requirements: Choose single- or dual-pump configurations based on actuator flow demands.
• Installation Space: Reserve sufficient axial clearance for dual-pump structures.
2. Alternative Models
• Same-Series Upgrade: If PV2R3-153 is discontinued, consider Yuken PV2R4 series dual pumps (e.g., PV2R4-180).
• Competitor Comparison:
• Denison T6 Series Dual Pumps: Similar performance but higher cost.
• Rexroth A10VSO Variable Pumps: Single-pump design requiring external flow dividers for dual circuits.
VII. Maintenance and Troubleshooting
1. Routine Maintenance
• Fluid Cleanliness: Maintain NAS 6 or ISO 4406 18/16 cleanliness levels; replace filters regularly.
• Temperature Monitoring: Operate within 40–60°C (avoid exceeding 85°C to prevent seal degradation).
• Periodic Inspections: Check oil levels, leaks, and noise every 500 hours; replace hydraulic fluid every 2,000 hours.
2. Common Faults and Solutions
【表格】
Symptom Potential Causes Solutions
Insufficient flow Worn vanes, clogged suction line Replace vanes, clean suction line
Pressure fluctuation Air ingestion, stator wear Bleed air, replace stator
Abnormal noise Bearing failure, misaligned coupling Replace bearings, realign coupling
Dual-pump flow imbalance Faulty regulator, internal leakage Inspect regulator, replace seals
VIII. Manufacturer Support
• Technical Resources: Yuken provides comprehensive product manuals, selection guides, and CAD drawings.
• After-Sales Service: Global authorized service centers offer spare parts and technical support.
