AZPFF-12-025/014RRR12MB SO040

The AZPFF-12-025/014RRR12MB SO040 pump is part of the AZPF External High Performance Gear Pumps series from Bosch Rexroth and is intended for pressure generation in mobile and stationary hydraulic automation. It delivers 25.0 cm³ per revolution in the first displacement stage and 14.0 cm³ per revolution in the second stage, allowing two flow rates within one housing. When viewed at the shaft the rotation is clockwise, matching typical right-hand driven power take-offs. Mechanical attachment is provided by a SAE-A 2-bolt flange, while the mounting pattern follows SAE J744 82-2 with an 82.55 mm pilot to ensure interchangeability with standard motors. The drive shaft withstands up to 110 Nm of torque under code R conditions, and UN threaded ports in accordance with ISO 11926-1 and ASME B1.1 accept common hydraulic fittings.

This model uses NBR sealing elements to resist petroleum-based fluids and maintain tight containment across the operating temperature range, and the rear cover is supplied without a valve to keep internal flow paths unobstructed. A splined shaft with a 15.456 mm major diameter transmits input power, while a through-drive rating of 65 Nm permits an additional unit to be mounted in series without overloading the coupling. These construction details support dependable service in compact power packs and machinery circuits where dual displacement capability and moderate auxiliary loads are required. This capacity enables designers to chain pumps for steering, fan drives, or other secondary functions without adding extra prime movers. The spline profile also centers the shaft accurately, minimizing torsional vibration and extending bearing life.
