pump cavitation

1. n. [Well Workover and Intervention]
A condition affecting an operating pump whereby the pump space is not fully charged with fluid being pumped. Pump cavitation may result from inadequate or restricted supply or from the introduction of air or gas into the fluid stream. The effect of cavitation depends on the type of pump. However, in most cases, it is an undesirable condition that causes a reduction in pump efficiency and excessive wear or damage to pump components.
