The AZPG-22-063RDC12MB SO039 belongs to the High Performance AZPG Gear Pumps series produced by Bosch Rexroth for hydraulic automation circuits where steady flow and moderate pressure are needed. It delivers a geometric displacement of 63 cm³ per revolution, giving predictable volume transfer in fixed-displacement systems. The pump can run up to 2300 rpm, allowing compact power units to achieve required flow without oversizing the prime mover, while a minimum speed of 500 rpm at viscosities near 12 cSt keeps lubrication intact during low-flow standby cycles. No restrictions on installation position simplify reservoir layout and permit mounting in any orientation. An SAE J744 22-4 13T splined drive shaft enables direct connection to common industrial engines; the profile conforms to the ANSI B92.1 13T 16/32 SP standard, so interchange with compatible couplings is straightforward. A 21.806 mm major spline diameter centers the shaft in the mating hub, and a 2.155 mm tooth thickness supports accurate torque transmission without excessive backlash.
Continuous system operation is supported up to 170 bar, giving the pump adequate headroom for typical mobile and industrial loops, while an intermittent rating of 200 bar covers short over-pressure events, and 230 bar is allowed for brief pressure peaks during quick directional changes. The drive section tolerates up to 300 Nm, matching the pressure limits without overstressing the shaft. A two-hole SAE J744 101-2 (B) mounting flange provides a standardized interface for bracket or bell housing attachment, and the 101.6 mm flange pilot diameter centers the body to minimize misalignment. Hydraulic connections are made through a 1 7/8-12 UN-2B threaded port, giving ample cross-section for the pump’s displacement and keeping pressure losses low.
