Rexroth PGH Gear Pump | R900951305, PGH3-22/016, PGH5-30/063, PGH4-2X/050

Rexroth PGH Series High-Pressure Low-Noise Internal Gear Pumps

Product Overview: The Rexroth PGH Series stands as the global industry benchmark for high-pressure industrial hydraulics. This featured selection includes core precision models: the Part Number R900951305 (PGH3-22/016RE07VU2), alongside high-capacity units PGH5-30/063RE11VU2 and PGH4-2X/050RE11VU2. Built on a precision internal gear principle, these pumps are specifically engineered to meet the rigorous demands of injection molding machines, press brakes, and heavy-duty industrial HPUs for ultra-high pressure (up to 350 Bar) and minimal operational noise. Their unique radial and axial pressure compensation ensures elite volumetric efficiency throughout the pump’s service life.

Key Technical Advantages:

• Ultra-High Pressure Resilience: Rated for a continuous operating pressure of 31.5 MPa with peaks reaching 35 MPa (350 Bar), built to handle extreme heavy-duty cycles.

• Extreme Low-Noise Operation: The internal gear design delivers decibel levels significantly lower than external gear pumps—perfect for modern “Silent Factory” initiatives.

• Low Pulsation & High Precision: Exceptional pressure stability protects downstream sensitive servo valves and actuators, enhancing final product machining accuracy.

• 100% Plug-and-Play Replacement: Strictly adheres to original Rexroth OEM specifications, including RE07/RE11 interface codes and VU2 sealing configurations, ensuring identical flange patterns, shaft ends, and port positions.

• Superior Wear Resistance: Reinforced bearings combined with hydraulic compensation technology minimize mechanical wear, offering an extended service life under continuous heavy loads.
