Parker PV062RIEC02 Hydraulic Piston Pump: Detailed Overview
TheParker PV062RIEC02is a variable-displacement axial piston pump designed for high-performance hydraulic systems. Below is a structured breakdown of its key features, technical specifications, applications, and advantages:
------
1. Key Features
• Variable Displacement:
• Adjustable flow output via swashplate angle control (enables energy efficiency by matching flow to demand).
• High Pressure Rating:
• Designed for continuous operation atup to 350 bar (5,076 psi), with peak pressures up to400 bar (5,802 psi).
• Compact & Robust Design:
• Axial piston configuration with a cast-iron housing for durability in heavy-duty applications.
• Integrated Electronics (IEC02 Variant):
• "IEC02"indicates built-in electronics for proportional flow/pressure control (e.g., CANbus communication, digital diagnostics).
• Noise Reduction:
• Optimized porting and internal geometry for low noise operation (critical for mobile and indoor machinery).

4. Advantages Over Other Pump Types
• Energy Efficiency:
• Variable displacement reduces energy waste by matching flow to load (unlike fixed-displacement pumps).
• Precision Control:
• Integrated electronics enable closed-loop control for accurate positioning and force regulation.
• Durability:
• Axial piston design withstands high pressures and cyclic loading better than gear or vane pumps.
• Compact Size:
• Higher power density (kW/kg) compared to alternative pump technologies.

5. Comparison with Parker’s PV Series Variants
【表格】
Model Variant Key Difference Best For
PV062 (Base) Standard variable displacement, no electronics Simple systems
PV062RIEC02 Integrated electronics (IEC02) for digital control Advanced automation
PV080 Larger displacement (80 cc/rev) Higher-flow applications
PV023 Smaller displacement (23 cc/rev) Compact systems
------
6. Maintenance & Reliability
• Service Intervals:
• Recommended oil changes every 2,000–5,000 hours (depending on operating conditions).
• Common Failure Points:
• Wear of swashplate bearings (high-pressure applications).
• Seal leakage (requires regular inspection).
• Pro Tips:
• Use ISO 46 or 68 hydraulic oil with a viscosity index ≥95.
• Monitor oil temperature (ideal range: 40–60°C / 104–140°F).
------
7. Cost Analysis
• Initial Purchase:
• Higher upfront cost vs. fixed-displacement pumps (due to electronics and precision engineering).
• Long-Term Savings:
• Energy savings from variable displacement offset initial costs in high-use applications.
• Replacement Parts:
• Swashplate, pistons, and valves are modular and replaceable (reduces downtime).
------
8. Manufacturer Support
• Parker Hannifinoffers:
• Global technical support.
• Customization options (e.g., special coatings for harsh environments).
• Training programs for hydraulic system designers.
