Product Overview
The Rexroth AZPW-21-011RQRXXMB-S0583 (material number R983032276) is a precision-engineered external gear pump from the AZPW series, designed for reliable hydraulic power generation in demanding industrial systems. This fixed-displacement pump operates on the external gear principle, utilizing two intermeshing precision-ground gears to draw hydraulic fluid from the suction port and displace it under pressure to the outlet. Manufactured to Bosch Rexroth’s stringent quality standards, the AZPW series is recognized for its robust construction, high volumetric efficiency, and consistent flow delivery across a wide range of operating conditions. With a nominal displacement of approximately 11 cm³/rev, this model is well-suited for continuous-duty applications requiring dependable hydraulic actuation and lubrication.
