The AZPFF-11-014/010RPRXXXXMB SO150 is an external gear pump from the AZPF External High Performance Gear Pumps series manufactured by Bosch Rexroth for hydraulic automation circuits. Its stage 1 displacement of 14 cm³ per revolution supplies a defined volume of fluid each rotation to drive actuators with predictable flow. Clockwise rotation allows the pump to couple directly to prime movers that turn in the same direction. A continuous pressure rating of 250 bar supports steady operation in high-pressure systems, while an intermittent limit of 280 bar tolerates brief overloads. The unit withstands peak transients up to 300 bar, safeguarding it during rapid valve shifts. Maximum speed capability of 3000 rpm lets designers obtain higher flow at elevated drive speeds, and a minimum operating speed of 500 rpm at 12 mm²/s viscosity under 100 bar ensures reliable suction during low-speed idle.
The minimum absolute suction pressure requirement of 0.7 bar protects the gear set from cavitation, and an absolute suction ceiling of 3 bar prevents over-loading the inlet seals. Required fluid cleanliness of ISO 4406 21/18/15 limits particulate contamination that could accelerate internal wear. NBR sealing material maintains compatibility with common hydraulic oils across typical temperature ranges. A 50 mm front cover specified as connection variant 1 provides a standardized mounting face for manifold or hose adapters. The drive shaft follows the ANSI B92.1 9-tooth 16/32 DP spline standard, and the usable spline length of 21.8 mm defines proper hub engagement depth. Through-drive torque capability of 65 Nm allows mechanical power to be passed to an additional downstream pump in tandem assemblies.
