The AZPF-1X-016-RRR20MB gear pump is manufactured by Bosch Rexroth within the AZPF External High Performance Gear Pumps series and supplies hydraulic oil for automated machinery. It moves 16 cm³ of fluid per revolution, establishing a predictable flow curve for circuit designers. A splined SAE J744 16-4 9T drive shaft secures the coupling so drive torque is conveyed without fretting. Continuous operation is permitted up to 250 bar, giving the pump capacity for medium-pressure control loops. A permissible speed of 3000 rpm sets the upper rotational limit for drive selection. Clockwise rotation aligns with power units that use right-hand crankshafts. Installation follows the SAE J744 82-2 (A) mounting flange, and the flange diameter of 82.55 mm matches standard adapters. M6 threads in the housing accept the mounting bolts that clamp the pump to the motor bracket. A rectangular flange port layout provides flat faces for tube fittings and simplifies seal replacement.

The design tolerates intermittent system loads at 280 bar and withstands 300 bar pressure spikes, allowing brief overloads during actuator acceleration. A maximum drive shaft torque of 110 Nm prevents spline distortion when the pump is started under high viscosity conditions. Bolt holes with an 11 mm diameter guide the fasteners and keep the housing centered on the prime mover. Each hole is drilled to a depth of 13 mm so the screws achieve full thread engagement. An NBR seal resists common hydraulic oils and maintains tightness under the stated pressure range. The assembled pump weighs 3.8 kg, enabling one-person handling during maintenance.
