Bosch Rexroth 1PF2G3-3X/023RA07MS External Gear Pump | 22.5cc High Pressure Hydraulic Pump Replacement

Product Overview

The 1PF2G3-3X/023RA07MS by LIC Hydraulic is a premium, high-pressure external gear pump engineered as a direct replacement for the Bosch Rexroth 1PF series. Designed for demanding industrial and mobile applications, our pumps prioritize “Interchangeability” and “Reliability.” Every unit undergoes 100% simulated operational testing to ensure it meets or exceeds OEM performance standards, providing a cost-effective yet high-quality solution for global hydraulic systems.

Key Technical Advantages

• Hydrostatic Axial Compensation: Utilizing floating bush technology, the pump automatically adjusts axial clearances to maintain superior volumetric efficiency even at maximum operating pressures.

• Quiet Operation: Advanced gear tooth profiling reduces flow pulsation and vibration, resulting in a significantly lower noise decibel level compared to standard gear pumps.

• Heavy-Duty DU Bearings: Equipped with reinforced DU composite bushings, the pump offers high load-carrying capacity and exceptional resistance to wear under continuous duty cycles.

• Perfect Interchangeability: All mounting dimensions, including the 4-bolt flange and shaft interface, are identical to the original Rexroth 1PF2G3 series for seamless integration.

Application Areas

• Mobile Hydraulics: Forklift steering and lifting systems, agricultural tractor auxiliary power, and construction equipment.

• Industrial Power Units: Compact hydraulic stations, machine tool lubrication, and plastic injection molding machinery.

• Material Handling: Aerial work platforms, scissor lifts, and dock levelers.

Expert Maintenance Tips

1. Priming: Always fill the pump with clean hydraulic fluid before the initial start-up to ensure internal lubrication and prevent “dry-run” damage.

2. Fluid Filtration: To maximize service life, maintain system cleanliness at ISO 4406 20/18/15 or better. Contamination is the leading cause of premature gear wear.

3. Drive Alignment: Ensure the coupling between the motor and pump is perfectly aligned. Any radial or axial misalignment can lead to bearing failure and seal leakage.
