Q: What does the model code "AZPB-32-3.1RCP02MB" mean?
A: It decodes as follows:
AZPB: Series code for external gear pumps.
32: Frame size / mounting flange diameter (32 mm).
3.1: Nominal displacement (3.15 cm³/rev).
R: Clockwise rotation (viewed from shaft end).
C: Tapered shaft 1:5.
P: Metric thread port.
02MB: Specific variant/cover code.
Q: Can this pump be used for high-pressure applications?
A: Yes. The AZPB series is designed for high load. This model can handle continuous pressures up to 220 bar and intermittent peaks up to 250 bar, making it suitable for industrial and mobile hydraulics.
Q: Is a counter-clockwise (CCW) version available?
A: Yes. Rexroth offers the same pump with counter-clockwise rotation (typically denoted by an 'L' in the model suffix, e.g., ...LCP...). Ensure you select the correct rotation for your drive direction.
Q: What is the recommended oil viscosity?
A: Operate within 10 to 300 mm²/s. For best efficiency and service life, maintain an operating viscosity between 16 and 25 mm²/s. Avoid prolonged operation at very low viscosity (<10 mm²/s) to prevent wear.
Q: What is the maximum allowable speed?
A: The absolute maximum speed is 4000 rpm. Exceeding this limit may cause cavitation and damage. For optimal performance, operate within the recommended range of 500 to 4000 rpm.
Q: How do I calculate the theoretical flow output?
A: Use the formula:
Flow (L/min) = Displacement (3.15 cm³/rev) × Speed (rpm) / 1000
Actual flow will be slightly less due to volumetric efficiency (typically 90-95% for gear pumps).
Q: What are common failure signs for this pump?
A: Watch for:
Noise: Whining or knocking indicates cavitation (low inlet pressure) or internal wear.
Reduced Flow/Performance: Often caused by worn gears or side plates.
External Leakage: Usually from the shaft seal (NBR) due to age or excessive shaft play.
Q: Can I repair this pump myself?
A: While Rexroth provides seal kits, the AZPB pump requires precise tolerances. Replacing bearings and seals is possible, but rebuilding the gear set typically requires factory-grade tools and pressure testing. For critical applications, consider an exchange unit.
Q: What causes premature failure?
A: Oil contamination (particles) is the #1 cause. Always maintain clean fluid (ISO 4406 class recommendation: 18/16/13 or better). Running with a clogged inlet filter or low oil level can cause cavitation and catastrophic damage.
