Description

1. Series Overview

The REXROTH AZPS series is a low-noise high-performance fixed-displacement external gear pump belonging to Platform F, designed for precision and low-vibration heavy-duty hydraulic systems. It features optimized pressure pulsation suppression, effectively reducing system noise and vibration, with durable sliding bearing structure for long-term heavy-load operation. Its core features are as follows:
  • Continuous Working Pressure: Up to 250 bar
  • Intermittent Working Pressure: Up to280 bar
  • Displacement Range: 4 ~ 28 cm³/rev
  • Low-noise Optimized Design: Reduced pressure pulsation and system vibration
  • Heavy-duty Sliding Bearing: Enhanced durability for continuous high-load operation
  • Standardized Interface: ISO/SAE compliant drive shafts and flange connections
  • Modular Combination: Support multi-pump combined assembly for integrated hydraulic solutions
