Product Overview
The Rexroth 1517 222 431 is a high-performance multiple external gear pump engineered by Bosch Rexroth for demanding industrial hydraulic systems. This unit combines two or more independent external gear pump stages within a single compact housing, driven by a common shaft to deliver multiple separate flow paths from one prime mover. Each stage operates on the proven external gear principle, where precisely meshed gear teeth rotate within a durable casing to trap and displace hydraulic fluid, providing consistent volumetric output proportional to rotational speed. The 1517 series is recognized for its robust construction, high power density, and excellent suction characteristics, making it a preferred choice for multi-circuit hydraulic systems requiring synchronized or independent flow distribution. This pump serves as a critical power source in centralized hydraulic power units, mobile machinery, and industrial manufacturing equipment where reliability and continuous duty operation are essential.

Engineering Features & Advantages
- Precision Performance: High-precision gear tooth geometry ensures minimal internal leakage, stable volumetric efficiency, and smooth, low-pulsation flow across all operating stages.
- Multi-Circuit Capability: Integrated multiple pump stages deliver independent flow paths from a single drive shaft, reducing installation space, coupling complexity, and overall system cost.
- Industrial Reliability: Built for continuous operation under severe industrial conditions with robust casing materials and wear-resistant bearing surfaces for extended service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, ensuring drop-in replacement without modification to existing hydraulic circuits.
- Excellent Suction Performance: Optimized inlet porting and gear chamber design provide superior suction characteristics, reducing cavitation risk at higher speeds.
Typical Industrial Applications
This multiple external gear pump is ideally suited for heavy industrial scenarios including plastic injection molding machines requiring separate clamping and injection circuits, metallurgical presses with multi-stage hydraulic control, construction and marine hydraulic systems needing independent implement and steering flows, and CNC machine tools where dedicated lubrication and actuation circuits are essential. Its robust design also serves centralized hydraulic power units in general manufacturing and mobile equipment applications.
