The AZPFF-12-014/008RRR1212MB SO040 gear pump belongs to the AZPF External High Performance Gear Pumps series and is manufactured by Bosch Rexroth. This double-section unit supplies hydraulic flow for automated circuits where compact high-pressure delivery is required. The pump rotates clockwise, allowing direct coupling to prime movers set for right-hand rotation. Section I delivers 14.0 cm³ per revolution to serve the primary pressure line, while section II delivers 8.0 cm³ per revolution for auxiliary actuators. Each section tolerates a continuous pressure of 280 bar so cylinders and motors can be driven without derating. Section I sustains shaft speeds up to 3000 rpm, supporting fast duty cycles in mobile machinery. The housing is fixed with a SAE J744 82-2 two-bolt mounting flange measuring 82.55 mm between centers, which aligns with common pump pads on industrial engines.
Power transmission relies on a 16/32 involute spline that meets ANSI B92.1, providing positive torque transfer without backlash; the usable spline length is 21.8 mm so the shaft engages fully with standard couplings. The flange is secured by M6 bolts seated to a depth of 13 mm, a detail that governs clamp load and prevents housing distortion. Section I pressure fluid exits through a 1 1/16-12 UNF-2B port, while section II uses a 7/8-14 UNF-2B outlet, enabling separate routing of the two flows. Matching suction connections use the same respective thread sizes to simplify hose selection and maintain uniform inlet velocities. These threaded interfaces, combined with the earlier parameters, complete the dimensional and hydraulic characteristics required for straightforward installation and reliable service in automated hydraulic systems.
