In the inch system a pump discharge pressure gage reads 120 psi. The pump suction pressure gage reads 20 psi. The pump is pumping the difference between these readings, so the pump is pumping 100 psi. At its BEP(best efficiency point) the pump should be running between 80% and 85% of its shut off head. 100 psi is 83% of 120 psi.
Centrifugal pumps are widely used in various industries for transferring fluids. However, like any other mechanical equipment, they can encounter issues that may hinder their performance. This troubleshooting guide aims to provide a comprehensive overview of common problems associated with centrifugal pumps and their possible solutions.

Centrifugal Pump Troubleshooting Chart
1. **Little or No Discharge**
- Check for air leaks in the suction line.
- Ensure the pump is primed properly.
- Inspect the impeller for blockages or damage.
- Verify that the discharge valve is fully open.
2. **Low Flow Rate**
- Check for clogs or obstructions in the suction or discharge lines.
- Inspect the impeller for wear and tear.
- Verify that the pump speed is set correctly.
- Check for air leaks in the suction line.
3. **Excessive Noise or Vibration**
- Inspect the pump and motor alignment.
- Check for loose or damaged components.
- Verify that the pump is properly secured to the base.
- Inspect the bearings for wear.

Operators will be introduced to the basic troubleshooting skills needed when a centrifugal pumps shows signs of failure. The course includes a review of basic hydraulic terminology and …
(There is also disagreement on the definition of "non‑cavitating head.") Figure 5 shows the test results obtained during an NPSH test on a centrifugal pump. Figure 5. Actual NPSH test points for a process centrifugal pump. To get an NPSH point, we held the capacity constant while reducing the NPSHA.
