Product Overview
The Rexroth 0510665381 / 1517222382 is a high-performance external gear pump engineered for demanding industrial hydraulic systems. Manufactured by Bosch Rexroth, a global leader in drive and control technology, this fixed-displacement pump operates on the external gear principle, utilizing two precision-meshed gears to draw fluid from the inlet port and displace it under pressure to the outlet. The 0510665381 / 1517222382 is designed for continuous-duty operation, delivering reliable flow and consistent pressure in applications where simplicity, durability, and hydraulic efficiency are paramount. Its robust construction and compact footprint make it a preferred choice for OEM and MRO replacement in heavy-duty machinery across multiple industries.
