Product Overview
The Rexroth AZPF-11-022RRR20KB-S0081 (material number 0510725102) is a high-performance external gear pump from the Bosch Rexroth AZPF series, engineered for reliable hydraulic power generation in industrial and mobile applications. This fixed-displacement pump operates on the external gear principle, utilizing a precision-machined driving gear and idler gear that rotate within a durable cast iron housing. As the gears mesh and unmesh, hydraulic fluid is drawn from the suction port and displaced to the pressure port with consistent volumetric efficiency. The AZPF series is renowned for its robust construction, compact footprint, and ability to deliver stable flow across a wide range of operating conditions. With a nominal displacement of approximately 22 cm³/rev, this model is well-suited for medium-pressure hydraulic systems requiring dependable, continuous-duty performance.
