What does the model code "AZPF-1X-011RCB20MB" mean?
It decodes as follows:
AZPF: Series code for high-pressure external gear pumps
1X: Frame size / bearing specification
011: Nominal displacement (11.0 cm³/rev)
R: Clockwise rotation
CB: Tapered shaft 1:5 with key
B20: Port and flange configuration (Square flange per ISO 8434-1)
MB: Variant code for seals and covers
Is this pump suitable for high-pressure applications?
Yes. The AZPF series is designed for heavy-duty use. This model can handle continuous pressures up to 250 bar and intermittent peaks up to 280 bar, making it ideal for industrial machinery and mobile hydraulics.
Can I get this pump in counter-clockwise rotation?
Yes. Rexroth typically offers a left-hand rotation version (denoted by an 'L' in the suffix, e.g., `...LCB...`). Always verify the rotation direction before installation.
What is the recommended operating viscosity?
Operate within 12 to 800 mm²/s. For optimal efficiency and service life, maintain viscosity between 20 and 100 mm²/s. Avoid prolonged operation below 12 mm²/s to prevent internal wear.
What is the maximum allowable speed?
The absolute maximum speed is 3500 rpm. However, the recommended continuous operating range is 1000 to 3000 rpm. Exceeding 3000 rpm may require special suction conditions (e.g., pressurized inlet) to avoid cavitation.
How do I calculate the flow output?
Use the formula: Flow (L/min) = Displacement (11.0 cm³/rev) × Speed (rpm) / 1000 Actual flow will be slightly less due to volumetric losses (typically 90-95% efficiency).
Reduced Flow: Often caused by worn gears or side plates due to contamination
External Leakage: Usually from the shaft seal (NBR), often due to age or excessive shaft play
Can this pump be repaired in the field?
While Rexroth provides seal kits, the AZPF pump uses precision sliding bearings and pressure-compensated side plates. Replacing seals is possible, but rebuilding the internal gear set requires specialized tools and pressure testing. For critical applications, an exchange unit is often recommended.
What is the #1 cause of premature failure?
Oil contamination. This pump requires very clean oil (NAS Class 9-10). Always use a pressure filter with a beta ratio (β10) ≥ 100. Running with a clogged suction filter or low oil level can cause cavitation and catastrophic damage.
Disclaimer: This data is based on standard Rexroth documentation for the AZPF series. Always refer to the official RE 10 250 datasheet for your specific application and safety guidelines.
