Product Overview
The Rexroth 0510 665 334 / 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 fixed-displacement unit uses a precision-meshed pair of external spur gears to draw hydraulic fluid from the reservoir and deliver it under pressure to the circuit. As a robust, self-priming pump, it is widely specified as the primary pressure source in open-loop hydraulic systems where dependable flow, compact installation, and long service life are essential. The dual model designation reflects Rexroth’s modular external gear pump platform, allowing straightforward integration and interchangeability across a broad range of machinery.
