The AZPF-12-022RRR12MB SO040 pump belongs to the AZPF External High Performance Gear Pumps series and is manufactured by Bosch Rexroth for hydraulic automation tasks that require dependable oil flow. Its geometric displacement of 22.5 cm³ per revolution fixes the volume delivered per shaft turn, making flow calculations straightforward. Continuous service at 180 bar permits the pump to hold working pressure during long duty cycles. A splined SAE J744 16-4 9T drive shaft with nine teeth under ANSI B92.1 16/32 sends torque into the gear set while controlling backlash. The shaft provides a minimum usable length of 21.8 mm so couplings grip securely. Clockwise rotation aligns with common engine output direction, avoiding reverse-drive adaptations. The unit weighs 4.0 kg, light enough for direct mounting on machine frames without auxiliary supports.
The design accommodates intermittent pressure to 210 bar and tolerates short peaks of 230 bar, giving margin against pressure spikes when valves shift. A two-bolt SAE J744 82-2 (A) mounting flange with an 82.55 mm pilot diameter centers the housing and withstands external loads. The mounting length of 55.1 mm and an overall length of 114.9 mm help equipment builders plan stack-up clearances in tight power packs. System plumbing connects to an 11/16-12 UN-2B pressure port and a 7/8-14 UNF-2B suction port, both selected for standard SAE straight-thread fittings that seal with O-rings. These connections, combined with the pressure ratings, let the pump integrate quickly into closed-loop or open-center hydraulic circuits.
