Bosch Rexroth AZPF-11-014RQR12MB external gear pump

AZPF-11-014RQR12MB, manufacturer material number 0510525031, is a Bosch Rexroth AZPF fixed-displacement external gear pump with geometric displacement 14 cm³/rev. The factory execution has clockwise rotation viewed on the drive shaft, parallel keyed shaft, sae j744 16-1 a and two-bolt sae a flange, 82.55 mm spigot. Body seals are NBR; the shaft seal is NBR. The standard rear cover has no integrated control valve.

The exact material-number row specifies intermittent pressure p2 = 230 bar and maximum speed 3000 rpm at p2. Intermittent loading is limited to 20 s by the pressure-definition diagram. These values are not continuous-pressure or peak-pressure settings. Minimum speed depends on the actual Series 1X, nominal size 14, pressure band and oil viscosity in the original table. Suction pressure 0.7–3 bar is absolute. Drive only clockwise as viewed on the shaft. Threaded line ports have limited service life when p2 exceeds 210 bar. The shaft-transfer table limits this Q drive execution to 220 bar, below the preferred-program row value of 230 bar. The stricter 220 bar shaft ceiling governs the published intermittent-pressure value; the row value is retained separately as catalog context.

The technical reference is manufacturer RE10089, edition 2021-11-24. Continuous viscosity is 12–800 mm²/s, with 20–100 mm²/s recommended; minimum speed must be selected from the matching size, bearing-series, viscosity and pressure-band row. The original exact material-number table gives a catalog mass of 3.65 kg.
