AZPF-12-011LNT20MB

The AZPF-12-011LNT20MB gear pump belongs to the AZPF External High Performance Gear Pumps series produced by Bosch Rexroth. It supplies fixed hydraulic flow for automation systems that need consistent pressure generation. The pump delivers a geometric displacement of 11 cm³ per revolution, providing a known volume for each drive cycle. Counterclockwise rotation is required, so drive arrangements must match that direction. A tang drive shaft transfers torque from the prime mover without keys or splines. Continuous operation is rated at 250 bar, enabling routine duty in medium-pressure circuits. Intermittent service can reach 280 bar to cover short transients. Pressure peaks up to 300 bar are tolerated, safeguarding the unit during rapid load changes. Mounting uses a four-bolt Ø52 mm pattern with an integrated seal ring to secure the housing to standard motor flanges. Each bolt threads into an M6 hole, defining the required fastener size. The assembly weighs 2.6 kg, easing manual installation inside compact power units.

For packaging inside tight manifolds, the housing length along dimension A is 44.5 mm and the overall height denoted as dimension B is 85.3 mm. Dimension C of 20 mm sets the axial distance from the mounting face to the shaft centerline, allowing proper coupling alignment. Fluid ports follow the square flange code 20, creating a rigid interface for pipe or hose connections. A 45 × 2.5 mm O-ring in the flange groove seals the pressure boundary against external leakage. Along the shaft, a 17 × 30 × 7 mm seal contains oil while permitting rotation. The compact axial length keeps pump overhang minimal and lowers bearing loads on the driving motor. These dimensional and sealing elements support reliable service in automated hydraulic modules where space is limited. Assembly time is shortened because the flange pattern aligns automatically with standard pump manifolds. The standardized port form also assists field replacement when servicing gear pumps within the same series.
