The AZPG-22-022RQC40MB belongs to the High Performance AZPG Gear Pumps series from Bosch Rexroth and delivers fixed-displacement flow for hydraulic automation circuits. It moves 22.5 cm³ of fluid per revolution to supply actuators with a consistent volume, and the rotor turns in a clockwise direction to match standard drive layouts. Power is transmitted through a parallel-keyed SAE J744 22-1 shaft, and the shaft key measures 6.35 mm by 25.4 mm in line with ANSI B17.2. The housing mounts on an SAE J744 101-2 two-hole flange with a 101.6 mm pilot diameter, while fastening is handled by 3/8-16 UNC-2B bolts inserted through 18 mm deep threads. Fluid lines attach by an SAE rectangular flange in UNC format, completing the mechanical interface set required for installation.
The pump operates continuously at 250 bar, carries the same 250 bar rating for intermittent duty, and tolerates pressure peaks up to 300 bar without structural damage. It sustains speeds to 3000 rpm so drive motors can run at common industrial frequencies. The suction port bore is 25 mm to minimize inlet losses, and the pressure port bore is 19 mm to keep discharge velocity within design limits. An NBR elastomer is used for all dynamic seals to resist typical hydraulic fluids, and the primary shaft seal measures 42 mm by 26 mm by 7 mm to control leakage along the drive end. Together these limits define operating windows that help engineers size circuits and protect the pump from overload.
