AZPF-11-008RARXXMB SO357

The AZPF-11-008RARXXMB SO357 gear pump is produced by Bosch Rexroth for the AZPF External High Performance Gear Pumps series and is intended to move hydraulic oil in automated machinery. A geometric displacement of 8 cm³ per revolution defines how much fluid is delivered with each shaft turn, allowing predictable circuit sizing. The unit operates safely up to 4000 rpm, so compact prime movers can reach the required flow without overspeeding the pump. An ISO Ø18 mm keyed drive shaft (Code A) provides a positive mechanical link to electric motors or engine PTOs, minimizing slip under load. Installation is streamlined by a SAE J744 82-2 mounting flange that matches common SAE-A two-bolt housings, letting designers attach the pump to standard brackets without adapter plates.

Clockwise rotation when viewed at the shaft end aligns the pump with drivetrain layouts that follow conventional right-hand rotation, eliminating the need for gearing to reverse direction. A front cover machined as a Ø82.55 mm two-bolt flange maintains accurate alignment with the mating housing and helps contain radial loads from the gears. The pump tolerates intermittent pressures up to 280 bar, supplying brief bursts of high force for cylinder actuation or relief-valve events. A shaft torque ceiling of 75 Nm sets the maximum drive torque the pump can accept, protecting the internal gear teeth from shear during overloads. These limits define safe operating windows for designers planning duty cycles in mobile or stationary hydraulic automation.
