Product Overview
The Rexroth PVV4-1X/122RB15DMC-K01 (Material Number: R900761040) is a high-performance fixed displacement vane pump engineered by Bosch Rexroth for demanding industrial hydraulic systems. Operating on the proven rotary vane principle, this pump utilizes a balanced rotor-and-vane assembly rotating within a precision cam ring to deliver a constant, predictable flow rate proportional to drive speed. The PVV4 series is specifically designed for continuous-duty operation, offering exceptionally low pulsation, quiet running characteristics, and outstanding volumetric efficiency. As a fixed displacement unit, it is ideally suited for systems requiring stable flow without the need for variable volume control, making it a reliable workhorse for machine tools, presses, and general industrial power packs.

Engineering Features & Advantages
- Precision Performance: The balanced vane design hydraulically compensates radial forces on the rotor shaft, significantly extending bearing life and ensuring consistent flow output even at higher pressures.
- Low Noise Operation: Optimized cam ring geometry and vane tracking minimize pressure pulsation and cavitation, resulting in exceptionally quiet operation suitable for noise-sensitive industrial environments.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, featuring a robust cast iron housing and wear-resistant internal components for long service intervals.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, ensuring drop-in replacement for existing Rexroth PVV4 series installations without modification.
- High Efficiency: Precision-machined cartridge kit (rotor, vanes, cam ring, and side plates) delivers high volumetric efficiency and minimal internal leakage.
Typical Industrial Applications
This fixed displacement vane pump is ideally suited for a wide range of heavy industrial scenarios, including plastic injection molding machines requiring stable clamping and injection pressure, metallurgical presses and rolling mills, construction and marine hydraulic systems, and CNC machine tools where precise, low-pulsation flow is critical for surface finish and accuracy. It is also commonly found in industrial power units and test stands demanding reliable,
