The AZPG-2X/063RQC40MB gear pump is produced by Bosch Rexroth and belongs to the High Performance AZPG Gear Pumps series. It delivers fixed flow in hydraulic automation systems that require reliable displacement. Each revolution moves 63 cm³ of fluid, giving designers a clear basis for flow calculations. Clockwise rotation aligns with common engine drives and prevents reverse flow in dedicated installations. Continuous duty is allowed up to 170 bar, and the pump operates safely at speeds to 2300 rpm for high-output circuits; it also maintains lubrication at a minimum 500 rpm when pressure is below 100 bar. Because the housing can be mounted in any position, layout options are flexible in compact power packs. A 25.4 mm shaft transmits torque to the pumping elements, and an NBR seal retains oil and resists standard hydraulic media.
The mounting face uses the SAE J744 101-2 two-hole B flange, while a 101.6 mm pilot centers the unit to reduce shaft misalignment. Fastening is completed with 1/2-13 UN-2B bolts that supply the clamping strength needed for working pressures. A 6.35 mm keyway in the shaft secures positive drive engagement. The pump tolerates intermittent loads to 200 bar and short pressure peaks to 230 bar, protecting the circuit during momentary spikes such as actuator deceleration. Its end cover is supplied without a valve, so flow control must be handled by external components. These interface details allow straightforward integration or replacement in standardized hydraulic modules.
