Rexroth PGF1-21 4,1RE01VU2 Hydraulic Gear Pump 500 L/min Flow Rate 5000 psi Maximum Pressure

The Rexroth PGF1-21 4,1RE01VU2 Hydraulic Gear Pump delivers exceptional performance with high efficiency and reliable operation for demanding industrial applications.

• High Efficiency Design: Advanced manufacturing processes ensure optimal performance with low energy consumption across various viscosity media
• High Pressure Capability: 280 bar nominal pressure rating supports stable operation in heavy-load applications
• Wide Flow Rate Range: Coverage from 5 cm³/rev to large displacement configurations
• Structural Reliability: Compact design with wear-resistant gears and corrosion-resistant components for extended service life
• Modular Flexibility: Supports multi-pump linkage for complex system configurations
• Environmental Performance: Low-noise operation (≤20 decibels) with vibration reduction technology
• Versatile Media Handling: Compatible with lubricating oil, hydraulic oil, fuel, and corrosive liquids

• Install hinge supports on piping during cold installation to prevent displacement after heating
• Heat-align coupling after pump body is heated to avoid equipment damage
• Prime with water or slurry before initial startup and verify motor rotation direction

• Install interlocking alarm at outlet pressure measurement point to prevent overload conditions
• Gradually increase speed during initial startup to avoid sudden pressure changes
• Regularly check lubricating oil levels and replenish as required
• Drain medium after extended disuse to prevent scaling or corrosion

• Regularly replace bearings and clean melt filters; avoid prolonged high-pressure operation
• Remove internal components during cleaning to prevent foreign matter contamination
• Maintain pump jacket temperature slightly below pipeline heat medium temperature
• Optimize bearing area temperature to enhance bearing capacity and longevity
