Rexroth AZPF Series High-Performance Hydraulic External Gear Charge Pumps

Product Overview: The Rexroth AZPF Series is a global cornerstone in hydraulic power transmission, renowned for its exceptional power density and modular flexibility. This selection features flagship configurations, including the high-pressure charge pump AZPF-12-008RHO30KB, high-displacement AZPF-12-022RFP20MB, part number 0510615318, and the customized AZPF-11-019LCP20KB-S0007. Constructed with high-strength extruded aluminum bodies and automatic axial pressure-compensated side plates, these pumps maintain elite volumetric efficiency at peak pressures up to 28 MPa. Whether utilized as a charge pump for closed-loop systems or a primary power source for mobile machinery, the AZPF series delivers factory-standard reliability.

Key Technical Advantages:

• Optimized Charge Performance: Specially engineered for closed-loop charge circuits, ensuring stable replenishment pressure across all speeds to prevent main pump cavitation.

• Extreme Pressure Resilience: Rated for continuous operation at 250 Bar with peaks up to 280 Bar (4060 PSI), featuring superior fatigue resistance for heavy-duty cycles.

• Axial Gap Compensation: Features patented pressure-balanced side plates to minimize internal leakage, maintaining efficiencies over 93% throughout the pump’s service life.

• Flexible Interface Options: Covering various flange and shaft combinations such as RHO30, RFP20, and LCP20, supporting specialized S0007 codes for a 100% precise match with OEM drive systems.

• Silent Operation: Precision-ground gear profiles drastically reduce pressure ripples and mechanical noise, enhancing the overall acoustic environment of the machinery.
