Product Description

Rexroth PGH4 & PGH5 Series Industrial High-Pressure Internal Gear Pumps

Product Overview: The Rexroth PGH Series stands as the global performance benchmark for industrial hydraulic systems, engineered for demanding environments requiring extreme operating pressures (up to 350 Bar) and ultra-low noise levels. This selection features core precision configurations: the high-flow PGH5-3X/100RE11VU2 and the mid-range PGH4-21/040RE11VU2, delivering flows up to 31.77 GPM. Utilizing advanced gap compensation technology, these pumps maintain elite volumetric efficiency even at low speeds, making them the premier power source for injection molding machines, die-casting equipment, and precision forming presses.

Key Technical Advantages:

  • Extreme Pressure Resilience: Rated for a continuous operating pressure of 31.5 MPa with peaks reaching 35 MPa (5075 PSI), built for heavy-duty industrial cycles.

  • Whisper-Quiet Operation: The internal gear meshing architecture delivers decibel levels far lower than external gear pumps, significantly improving the workshop environment.

  • Minimal Flow Pulsation: Exceptionally smooth fluid delivery reduces pipe vibration and protects downstream sensitive components, extending system lifespan.

  • Superior Volumetric Efficiency: Equipped with radial and axial gap compensation mechanisms, maintaining efficiencies over 95% across the full pressure range to minimize energy loss and heat buildup.

  • Extended Service Life: Hardened internal rings and pinion gears ensure an exceptionally long operational cycle under continuous high-frequency load conditions.

Detailed Models & Parameters:

  • Core Series: Rexroth PGH4, PGH5 Series.

  • Model Keywords: PGH5-3X/100RE11VU2, PGH4-2X, PGH4-21/040RE11VU2.

  • Key Flow Rate: High-capacity delivery including 31.77 GPM (approx. 120 L/min at 1450 RPM).

  • Pressure Ratings: Rated at 315 Bar; Peak up to 350 Bar (5075 PSI).

  • Sealing Material: Features U2 (FKM/Viton) seals for superior temperature and chemical resistance.

  • Target Applications: Servo-pump drive systems, clamping circuits for injection molding, precision presses, and die-casting machinery.
