Frequently Asked Questions
Basic Parameters & Selection
Q: What is the displacement and pressure rating of this pump?
A: The geometric displacement is 11.0 cm³/rev. It has a maximum continuous working pressure of 250 bar, an intermittent pressure of 280 bar, and a peak pressure of 300 bar.
Q: What type of shaft does this model have?
A: This model (RQR) features a straight shaft with a keyway, which is different from the tapered shafts found in some other AZPF models (like RCB).
Q: What is the rotation direction?
A: Clockwise rotation when viewed from the shaft end.
Installation & Commissioning
Q: What are the critical installation requirements?
A:
  • Shaft Alignment: Use a flexible coupling. Radial runout should be < 0.1 mm, angular error < 1 degree. Rigid connections cause bearing failure.
  • Suction Conditions: Inlet absolute pressure must be ≥ 0.7 bar to prevent cavitation. Use a flooded suction or boost pump for high-speed operation.
  • Priming: Never run the pump dry. Fill the housing with clean oil before the first start.
Q: How should the case drain port be connected?
A: The drain line must connect directly to the tank (no valves/filters), below the fluid level but above the pump centerline. Backpressure must not exceed 1 bar.
Operation & Troubleshooting
Q: The pump is very noisy. What is the cause?
A: Noise is usually cavitation (whining) or aeration (crackling).
  • Cavitation: Check for clogged inlet filters, high oil viscosity, or low oil level.
  • Aeration: Check for air leaks in the suction line.
  • Mechanical Noise: Check for shaft misalignment or worn bearings.
Q: How do I calculate the actual flow output?
A: Theoretical flow = 11.0 (cm³/rev) × Speed (rpm) / 1000. Actual flow will be 5-10% lower due to internal leakage. A drop of more than 15% indicates significant wear.
Q: The pressure does not reach the rated value. What is wrong?
A: Common causes include:
  1. Internal Wear: Increased clearance between gears and side plates.
  2. System Leakage: Check relief valves and actuators.
  3. Low Motor Speed or incorrect system settings.
Maintenance
Q: What type of oil and cleanliness are required?
A: Use ISO VG 32/46/68 mineral-based oils (HL, HLP). The oil cleanliness must be NAS Class 9 or cleaner (ISO 4406 18/16/13) for long bearing life.
Q: Can I repair this pump myself?
A: Not recommended for critical applications. While seals can be replaced, rebuilding the precision sliding bearings and pressure-compensated side plates requires special tools and testing. An exchange unit is often safer.
Q: What is the expected service life?
A: Under correct conditions (clean oil, proper viscosity, rated load), the B10 life can reach several thousand hours. Oil contamination is the primary cause of premature failure.
