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 and port connection does this model have?
A: This model (RAB) features a straight cylindrical shaft (Ø18 mm) with a keyway. The port connection is Pipe Thread (ISO 228-1 / BSP), which is different from the metric threaded or flanged ports found in other AZPF models.
Q: What is the rotation direction?
A: Clockwise rotation when viewed from the shaft end.
Q: What are the critical installation requirements?
A:
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.
Q: The pump is very noisy. What is the cause?
A: Noise is usually cavitation (whining) or aeration (crackling).
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:
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.
