Bosch Rexroth AZPF-11-004LAB01MB external gear pump

AZPF-11-004LAB01MB, manufacturer material number 0510225318, is a Bosch Rexroth AZPF fixed-displacement external gear pump with geometric displacement 4 cm³/rev. The factory execution has counter-clockwise rotation viewed on the drive shaft, parallel keyed shaft, iso 18 mm and rectangular flange, 80 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 = 280 bar and maximum speed 4000 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 4, pressure band and oil viscosity in the original table. Suction pressure 0.7–3 bar is absolute. Drive only counter-clockwise as viewed on the shaft. Threaded line ports have limited service life when p2 exceeds 210 bar.

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 3.3 kg.

The shared drawing heading carries S0356, which is absent from this SPC designation. Exact article installation geometry remains unconfirmed; only the literal material-number table values and separately documented type-key interfaces are used.
