4. Install a venturi: A venturi installed in the suction line can help create an area of low pressure, which can reduce the chance of cavitation.

5. Install a priming valve: A primer valve can help reduce the suction head and thus reduce the chance of cavitation.

6. Install a vacuum breaker: A vacuum breaker can be used to reduce the pressure in the suction line, thus reducing the chance of cavitation.

7. Improve the suction piping: Improving the suction piping, such as using larger pipes, can reduce the chance of cavitation.

8. Inspect the pump and suction line: Inspecting the pump and suction line for any signs of wear or damage can help reduce the chance of cavitation.

Air in a centrifugal pump usually occurs because of a suction issue. Air can be introduced into the pump either because of a piping issue, such as low water level, or an internal issue, such as incorrect impeller clearance. To prevent air from entering the inlet pipe and pump body, the piping should be checked to ensure it is properly sealed and the pump should be regularly inspected to check impeller clearance.
