What is cavitation in pumps

Cavitation in pumps is an all too common, detrimental condition often found in centrifugal pump installations.

What are the 4 causes of cavitation in a pump

Cavitation can reduce pump efficiency, cause vibration and noise and lead to significant damage to a pump’s impeller, casing, shaft and other internal components. The cavitation phenomenon occurs when the pressure of the fluid in the pump falls below the vapor pressure, causing vapor bubbles to form at low-pressure pockets.

These vapor bubbles violently collapse or “implode” as they enter higher pressure areas. This can lead to mechanical damage to pump internals, provide weak points susceptible to erosion and corrosion and impair pump performance.

Understanding and implementing strategies to mitigate cavitation is crucial for maintaining the operational integrity and longevity of centrifugal pumps.

Types of Cavitation in Centrifugal Pumps

To reduce or prevent cavitation in a centrifugal pump, it is important to understand the different types of cavitation that may occur.

These include:
