Product Overview
The Rexroth 0510525072 (also designated R902650577) 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 durable cast iron housing to draw hydraulic fluid from the reservoir and deliver it under pressure to the circuit. As a fixed-displacement unit, it provides a constant flow rate proportional to drive speed, making it an ideal solution for systems requiring reliable, continuous fluid delivery without the complexity of variable displacement controls. The 0510525072 / R902650577 is widely recognized for its robust construction, high volumetric efficiency, and long service life in heavy-duty applications.
