Product Overview
The Rexroth 0510 665 934 / 1517 222 414 is a high-performance external gear pump engineered by Bosch Rexroth for demanding industrial hydraulic systems. Operating on the positive displacement principle, this pump utilizes two precision-meshed external spur gears rotating within a hardened casing to draw hydraulic fluid from the inlet port and deliver it under pressure to the outlet. The interlocking gear teeth create a continuous sealing line that traps and transports fluid with minimal internal leakage, ensuring consistent volumetric efficiency across the operating range. With a robust cast-iron housing and a fixed-displacement design, this gear pump serves as a reliable pressure source in centralized lubrication circuits, power units, and auxiliary hydraulic systems where simplicity, durability, and steady flow delivery are paramount.

Engineering Features & Advantages
- Precision Gear Meshing: Hardened and ground external spur gears ensure tight tooth clearance, minimizing internal leakage and maintaining high volumetric efficiency throughout the service life.
- Robust Casing Construction: The durable housing withstands continuous high-pressure operation and resists deformation under peak load conditions, extending pump longevity in severe industrial environments.
- Stable Flow Delivery: The fixed-displacement gear design provides consistent, pulsation-minimized flow output proportional to drive speed, ideal for systems requiring predictable hydraulic supply.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with excellent resistance to contamination and thermal stress.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM Rexroth specifications, ensuring drop-in installation without modification.
Typical Industrial Applications
This Rexroth external gear pump is widely deployed in plastic injection molding machines for mold clamping and injection circuits, metallurgical presses requiring reliable low-pressure auxiliary flow, construction and marine hydraulic systems for steering and implement circuits, and CNC machine tools where consistent lubrication and coolant delivery are essential. Its fixed-displacement design also makes it a preferred choice for centralized lubrication power units and industrial power packs demanding simple, durable, and maintenance-friendly hydraulic supply.
