Engineering Features & Advantages
- Precision Gear Geometry: Hardened and ground spur gears with optimized tooth profile minimize internal leakage and pressure pulsation, ensuring smooth flow delivery across the entire speed range.
- Dual-Stage Versatility: Two independent pumping sections (019/019) allow simultaneous supply to separate circuits or combined flow for high-demand actuators, reducing system complexity and component count.
- Industrial Reliability: Heavy-duty cast-iron housing and high-load journal bearings are engineered for continuous operation under severe industrial conditions, including high shock loads and contaminated environments.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, including shaft end, flange, and port configurations, enabling drop-in installation without modification.
Typical Industrial Applications
This Rexroth external gear pump is widely deployed in plastic injection molding machines for clamp and injection circuits, metallurgical presses requiring reliable low-pressure pilot and cooling flows, construction and marine hydraulic systems for steering and auxiliary functions, and CNC machine tools where consistent lubrication and coolant delivery are critical. Its dual-stage design is particularly suited for mobile equipment needing independent flow paths from a single compact power source.
