The AZ-P-F-12-019-RRR12MB SO040 gear pump belongs to the AZPF External High Performance Gear Pumps series from Bosch Rexroth and is intended to supply fixed-displacement flow in hydraulic automation systems. It moves 19 cm³ of fluid per revolution, so flow can be calculated directly from drive speed. A maximum speed rating of 3000 rpm allows the pump to run on compact prime movers while maintaining efficiency, and intermittent working pressure can reach 230 bar for short high-load cycles. Correct installation requires clockwise rotation, which sets the inlet and outlet positions. The housing mounts on an SAE-A two-bolt flange with an 82.55 mm diameter that matches common PTO pads, and the overall mass is 3.9 kg, permitting single-person handling during maintenance.
Pressure and suction lines connect through 1 1/16-12 UNF-2B threads, keeping hose sizes identical on both ports; each thread is cut to a depth of 19 mm to secure fittings under load. Drive torque is transmitted by a 16⁄32 splined shaft specified in ANSI B92.1, providing positive engagement with standard hubs. The pump accepts absolute suction pressures between 0.7 and 3 bar, enabling reservoir placement either below or slightly above the inlet. Optimum performance is achieved when oil viscosity stays within 20–100 mm²/s, ensuring stable hydrodynamic lubrication. NBR seals contain the working fluid and resist petroleum-based oils, maintaining leakage control throughout the service life.
