The AZPF-12-005LRR12MA pump is built by Bosch Rexroth in the AZPF External High Performance Gear Pumps series. It supplies hydraulic flow for automation systems requiring compact positive-displacement units. A geometric displacement of 5.0 cm³ per revolution defines the volume moved each time the gears turn. The pump accepts shaft input up to 4000 rpm so drive sizing can match high speed prime movers. Rotation is counter-clockwise, allowing direct coupling to power sources that follow the same rotation sense. Power is transferred through a SAE J744 16-4 9T spline drive shaft for standardized connection, and a usable spline length of 21.8 mm must be engaged to avoid fretting. Installation relies on a SAE J744 82-2 (A) two-bolt mounting flange, while the 82.55 mm flange diameter establishes the bolt circle. The assembly weighs 3.2 kg, which assists in selecting brackets and supports without over-specifying hardware.
For duty cycles that see pressure peaks, the unit tolerates up to 280 bar intermittently, enabling it to run actuators with moderate load surges. An ambient temperature window from -30 to +80 °C permits operation in cold starts or warm machine rooms. Continuous service is allowed with oil viscosities between 12 and 800 mm²/s, and a narrower recommended range of 20 to 100 mm²/s optimizes volumetric efficiency. NBR sealing material provides compatibility with common mineral-based hydraulic fluids and supports the stated temperature band. The pressure port uses a 9/16-18 UNF-2B thread, matching common tube fittings, and the suction port shares the same thread size to simplify inventory. Both ports are machined with a 13 mm thread depth so fittings seat fully without bottoming. These interface details let designers integrate the pump quickly into standardized manifolds and hose assemblies.
