The AZPF-11-005RQRXXMB SO140 gear pump belongs to the AZPF External High Performance Gear Pumps series produced by Bosch Rexroth. It delivers 5.5 cm³ per revolution, providing a fixed volumetric flow suitable for compact hydraulic circuits. Clockwise rotation matches engines or motors with a standard right-hand drive, and a parallel keyed shaft according to SAE J744 16-1 A ensures straightforward coupling to power sources. The shaft diameter is 15.875 mm, while a 4 x 20 mm key secures torque transfer without slip. A two-bolt SAE J744 82-2 (A) mounting flange speeds installation, and the 82.55 mm pilot diameter centers the housing relative to the prime mover. A 106.4 mm flange bolt circle defines the hole spacing so that the pump aligns with common SAE adapters.
Its hydraulic limits permit 280 bar during intermittent duty and brief peaks up to 300 bar, enabling the pump to feed cylinders or motors that demand high transient pressure without structural overload. Continuous operation is supported to 4000 rpm at port P2, while a minimum 500 rpm at pressures below 100 bar prevents inadequate lubrication at low speed. NBR seals resist common petroleum-based fluids and maintain internal tightness across the stated pressure range. The housing weighs 3.3 kg, light enough for single-person handling when servicing compact power units. M6 mounting threads cut to a depth of 13 mm provide secure bolt engagement, preventing loosening under vibration and completing a rigid connection between the pump and its supporting bracket.
