bubbles and collapsing of those bubbles at the ‘eye of the impeller’ and that is termed as cavitation.

The pressure in the suction line can drop due to serval reasons.

●     The suction line has too many turns and bends (avoid that, talk to layout and piping engineers)

●     Plugged strainer or filter in the suction line (ensure the line is clean, maintenance is necessary)

●     Rusted Pipe results in friction losses (keep an eye on those and change if necessary)

●     Low level in the suction vessel (make sure that it operates at operating set point or close to it)

●     Damaged fittings over a period and so forth
