Rexroth Vane Pump PGH4-21 040RE11VU2 Smooth And Durable Hydraulic Performance

The Bosch Rexroth PGH4-2X/040RE11VU2 (R900086321) is a high-performance hydraulic pump designed for reliable operation in demanding applications. This internal gear pump features:

• Gap compensation with constant displacement for high efficiency
• Robust construction with hydrodynamically supported pinion shaft
• Optimized fluid flow with 180° suction range
• Effective chamber separation via sickle-shaped segment filler element
• Low noise operation due to involute tooth system
• Broad viscosity and speed range compatibility
• Maximum operating pressure of 5000 psi
• Compatible with various configurations and pump combinations

The pump's hydrodynamic and hydrostatic mounting system accommodates forces on both the pinion shaft and internal gear, ensuring durable performance. Its radial compensation system maintains nearly leakage-free operation across pressure ranges.
