AZPFF-12-008/008RQR1212MB SO014

The AZPFF-12-008/008RQR1212MB SO014 pump belongs to the AZPF External High Performance Gear Pumps series and is manufactured by Bosch Rexroth. It supplies fixed displacement flow for hydraulic automation where reliable pressure generation is required. Direction of rotation is clockwise, allowing direct coupling to right-handed prime movers. A parallel keyed drive shaft conforming to SAE J744 16-1 A transmits torque, and the shaft end diameter of 17 mm defines the coupling dimensions. The housing mounts via a 2-bolt 82.55 mm flange according to SAE J744 82-2, streamlining alignment with standard motor brackets. Sealing is provided by NBR material to contain typical hydraulic oil. The first pumping section delivers a geometric displacement of 8 cm³ per revolution, establishing the base flow rate delivered per shaft turn.

The second pumping section also displaces 8 cm³ per revolution, so the combined assembly maintains equal flow from both stages. A maximum permitted speed of 4000 rpm broadens usage in systems that run high rotational inputs while staying within volumetric efficiency limits. Each section includes a suction port threaded 7/8-14 UNF-2B for inlet connection and a matching pressure port of the same thread for discharge, simplifying hose selection and reducing inventory of fittings. These port sizes align with common hydraulic line dimensions and help keep pressure losses low at rated flow. Together, the balanced displacement, high speed capability, and standardized porting allow the pump to integrate into compact multi-circuit hydraulic manifolds without custom adapters.
