Product Overview

The Rexroth AZPN-11-032/011RDC72OKE (Material Number: R918C02593) is a high-performance external gear pump engineered by Bosch Rexroth for demanding industrial hydraulic systems. Operating on the proven external gear principle, this unit features two precision-meshed gears rotating within a hardened casing to draw fluid from the suction port and displace it under pressure at the outlet. The AZPN series is a dual-displacement (tandem) configuration, combining a 32 cm³/rev primary stage with an 11 cm³/rev secondary stage on a common drive shaft, allowing two independent flow circuits to be supplied from a single prime mover. With a robust cast-iron housing, high-precision gear teeth, and pressure-balanced bearing bushes, this pump delivers consistent volumetric efficiency, low pulsation, and long service life in continuous industrial duty.

Engineering Features & Advantages

Precision Gear Performance: Hardened, precision-ground gear teeth and pressure-balanced bearing bushes minimize internal leakage and deliver high volumetric efficiency across the full operating range.
Tandem Dual-Stage Design: Two independent displacements (32 + 11 cm³/rev) on a single drive shaft reduce installation footprint and eliminate the need for a second pump and coupling.
Low Pulsation & Quiet Operation: Optimized gear geometry and rigid casing construction reduce flow ripple and noise emission, ideal for sensitive industrial environments.
Industrial Reliability: Built for continuous operation under severe industrial conditions, with excellent resistance to contamination and long bearing service life.
Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in replacement without system modification.

Typical Industrial Applications

This Rexroth AZPN tandem gear pump is widely deployed in plastic injection molding machines requiring dual-circuit actuation, metallurgical presses and rolling mill lubrication systems, construction and marine hydraulic power units, and CNC machine tool hydraulic power packs where reliable, low-noise flow delivery is essential. Its dual-stage configuration is particularly suited
