AZ-P-F-12-019-RRR20MB

The AZ-P-F-12-019-RRR20MB is produced by Bosch Rexroth within the AZPF External High Performance Gear Pumps series. It supplies fixed-displacement flow for hydraulic automation circuits and is configured for clockwise rotation to match conventional engine drives in mobile machinery. The model delivers 19 cm³ per revolution, establishing a defined volumetric output that simplifies sizing of actuators and valve networks. Operating speeds can reach 3000 rpm, allowing the unit to support fast cycle tasks without cavitation when properly supplied. Intermittent system demand can be met because the housing tolerates pressures up to 230 bar, enabling compact layouts that still achieve high force levels. Power is transmitted through a splined drive based on the SAE J744 16-4 9T interface, so the unit can couple directly to standard PTO adapters. The shaft journal diameter is 17 mm, and its nine-tooth spline with a major diameter of 15.456 mm centers the input torque while maintaining alignment.

Installation follows the SAE J744 82-2 (A) two-bolt flange pattern, and the 82.55 mm flange diameter positions the inlet and outlet close to the mounting face to reduce plumbing length. M6 mounting bolts can be threaded to a depth of 13 mm, providing enough engagement to resist pulsation loads without stripping aluminum housings. Each spline tooth measures 2.357 mm in thickness, giving adequate shear area for the transmitted torque. A minimum usable spline length of 21.8 mm ensures full engagement with mating shafts even when axial tolerances accumulate. The dry mass is 3.9 kg, so the pump can be supported by lightweight brackets on mobile equipment without exceeding vibration limits. Together these physical characteristics align with the hydraulic ratings already noted and support dependable operation in closed-loop or open-center systems.
