Product Overview
The Rexroth PGH5-30/080RE11VU2 (Material Number: R901147116) is a high-performance internal gear pump engineered by Bosch Rexroth for demanding industrial hydraulic systems. Operating on the proven internal gear principle, this fixed-displacement pump features a pinion shaft driving an internally toothed ring gear, with a crescent-shaped filler piece separating the suction and pressure chambers. This design delivers exceptionally smooth, low-pulsation flow with minimal noise emission, making it a preferred solution for applications where quiet operation and precise volumetric consistency are critical. The PGH5 series is a compact, robust unit well suited for continuous duty in centralized lubrication systems, machine tools, and general industrial power packs.

Engineering Features & Advantages
- Precision Internal Gear Performance: The pinion and internal ring gear mesh with a crescent filler to produce uniform, low-pulsation flow, ensuring stable actuator movement and reduced system vibration.
- Low Noise Emission: The internal gear principle inherently minimizes pressure ripple and cavitation, resulting in significantly quieter operation than comparable external gear pumps — ideal for noise-sensitive installations.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened gear surfaces and a robust casing that withstands high radial and axial loads.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in replacement without modification to mounting or piping.
Typical Industrial Applications
This Rexroth PGH5 internal gear pump is widely deployed in plastic injection molding machines, metallurgical presses, CNC machine tools, and centralized lubrication systems. Its smooth, quiet flow characteristics also make it suitable for marine hydraulics, construction equipment power packs, and general industrial hydraulic power units requiring dependable fixed-displacement performance.
