The AZPG-22-040RDC12MA gear pump belongs to the High Performance AZPG Gear Pumps series and is produced by Bosch Rexroth. It supplies fixed-displacement flow for hydraulic automation circuits. The geometric displacement is 40 cm³ per revolution, establishing the volume moved each shaft turn. A clockwise rotation direction is specified, so drive orientation must follow that convention. The unit permits shaft speeds up to 2 800 rpm, matching high-speed motor outputs. An end cover with axial pressure and suction ports aligns inlet and outlet on the same axis to simplify manifold layout. The housing mounts with a SAE-B flange, and the two-hole 101.6 mm pattern defined in SAE J744 101-2 positions the pump securely on standard power take-off faces.
Operating limits include a continuous pressure of 250 bar, an intermittent rating of 280 bar, and a peak capability of 300 bar, allowing the pump to serve medium-pressure circuits. The drive can transmit up to 300 Nm through shaft form D without overstress. Fluid exits through a pressure port threaded 1 5/16-12 UN-2B, while supply oil enters via a suction port threaded 1 5/8-12 UN-2B; both ports follow the SAE thread UN-2B profile with BOSS O-ring seats to maintain seal integrity. Static sealing throughout the pump uses NBR material to resist common hydraulic oils. Power is delivered through a spline cut to ANSI B92.1 13T 16/32, ensuring shaft compatibility with standardized couplings.
