The AZPFF-12-014/008LQR12MB SO516 pump belongs to the AZPF External High Performance Gear Pumps series and is produced by Bosch Rexroth. It is a tandem gear pump with two sections to supply separate circuits in hydraulic automation systems. The first section displaces 14 cm³ per revolution while the second section delivers 8 cm³ per revolution, allowing designers to combine flows within one housing. The unit rotates counter-clockwise, so inlet and outlet orientation must match this direction. Power is transmitted through a 15.875 mm parallel keyed drive shaft that follows the SAE 16-1A profile, and the key measures 4 x 20 mm according to DIN 6885 for secure torque transfer. Continuous shaft speed can reach 3000 rpm at port P2 without cavitation, which supports fast cycle machinery.
Hydraulic limits are defined by a continuous pressure rating of 250 bar for both pump sections, an intermittent capability of 280 bar, and a peak limit of 300 bar that may be sustained for up to 20 seconds. The housing bolts to machinery with an SAE J744 82-2 (A) two-bolt flange, and the threaded holes accept M6 fasteners to a depth of 13 mm, which simplifies direct mounting to common motor adaptors. These connection features, together with the pressure margins stated above, enable the pump to maintain stable flow in compact power units and mobile platforms where high performance and standardized interfaces are required.
