Description

AZPF-11-014RRR12MB, manufacturer material number 0510525041, is a Bosch Rexroth AZPF fixed-displacement external gear pump with geometric displacement 14 cm³/rev. Its Series 1X execution has standard bearings, and clockwise rotation viewed on the drive shaft. The pump must be driven only in that direction.

The interface uses splined shaft, sae j744 16-4, 9 teeth and two-bolt sae a flange, 82.55 mm spigot, with UN O-ring threads, ISO 11926-1 / ASME B1.1. Body seals are NBR; the shaft seal is NBR. The standard rear cover has no integrated pressure relief or flow-control valve. The seal-specific fluid and ambient temperature range is -30 to 80 °C, subject to hydraulic-fluid and viscosity conditions.

For this size and bearing series, continuous pressure p1 is 250 bar, intermittent pressure p2 is 280 bar and short pressure peaks p3 are limited to 300 bar. These are separate operating limits. The manufacturer pressure diagram limits the intermittent loading period to 20 s. The maximum speed is 3000 rpm at p2; minimum speed varies with pressure and viscosity as listed in the specifications. Suction-port pressure must remain between 0.7 and 3 bar absolute. Threaded line ports have limited service life above 210 bar intermittent pressure.

The technical reference is the original manufacturer publication RE10089, edition 2021-11-24. Its exact preferred-program material-number row and installation drawing apply; other configurations on shared source pages are contextual. Continuous viscosity is 12–800 mm²/s, with 20–100 mm²/s recommended. The flow and power curves use viscosity 32 mm²/s and fluid temperature 50 °C. Representative manufacturer AZPF series photograph; shaft, flange, rotation and seal execution are established by the exact article code and drawing, rather than this photograph.
