The AZPG-22-040RDC07KB SO081 gear pump belongs to the High Performance AZPG Gear Pumps series and is manufactured by Bosch Rexroth for hydraulic automation circuits. It provides a geometric displacement of 40 cm³ per revolution to deliver a steady volume flow at each shaft turn. The unit is configured for clockwise rotation, supporting standard right-hand drive layouts in mobile or industrial power packs. Reliable operation begins at a minimum speed of 500 rpm when system pressure remains below 100 bar, while a permissible speed of 2800 rpm at port P2 allows higher flow demands. Torque is transferred through an SAE J744 22-4 13T splined shaft, and the drive side withstands up to 300 Nm so the pump can transmit rated power without slipping.
Installation uses an SAE J744 101-2 (B) mounting flange and the pressure ports are formed by an SAE rectangular flange with metric threads, so hoses or rigid lines can be attached without adapters. Under normal duty the housing holds 250 bar continuously; it endures 280 bar for intermittent load cycles and accepts brief spikes to 300 bar when actuators stall or reverse. These limits preserve gear integrity and reduce fatigue on the shaft. Sealing is handled by NBR elements around the casing together with an FKM shaft seal at the drive end, preventing external leakage while coping with fluid temperatures common to mineral oils.
