Product Overview
The Rexroth PGF1-21/2.8RE01VU2 (material number R900086161) is a precision-engineered internal gear pump from the Rexroth PGF series, designed for reliable hydraulic power generation in industrial and mobile applications. This fixed-displacement pump operates on the internal gear principle, utilizing an internally toothed ring gear and a smaller externally toothed pinion gear to create a sealed displacement volume. As the gears rotate, hydraulic fluid is drawn from the suction port and displaced to the pressure port with minimal pulsation and low noise emission. The PGF1 series is renowned for its compact design, high volumetric efficiency, and exceptional suction performance, making it an ideal choice for continuous-duty industrial hydraulic systems requiring stable flow and long service life.

Engineering Features & Advantages
- Precision Internal Gear Design: The PGF1 series utilizes a precision-machined internal gear set with a fill piece that creates a reliable seal between suction and pressure chambers, ensuring high volumetric efficiency and consistent flow output across the operating range.
- Low Noise & Low Pulsation: The internal gear principle delivers exceptionally smooth fluid displacement with minimal pressure ripple, significantly reducing noise emission compared to external gear pumps — ideal for noise-sensitive industrial environments.
- Excellent Suction Performance: Designed with optimized inlet geometry, this pump maintains stable operation even at high speeds and with elevated fluid viscosity, preventing cavitation and ensuring reliable performance in demanding circuits.
- Industrial Reliability: Built for continuous operation under severe industrial conditions with robust bearing support, hardened gear surfaces, and high-quality sealing materials for extended service intervals.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth standards, allowing straightforward retrofit into existing hydraulic systems without rework.
