Early warning signs of cavitation in pumps
Gravel noise, vibration and falling head: spot cavitation before damage occurs.
Cavitation is the collapse on the impeller of vapour bubbles formed when suction pressure drops below the liquid’s vapour pressure. Its typical symptom is a “gravel” noise from inside the pump.
Keep NPSH available at least 0.5 m above NPSH required and avoid unnecessary elbows and reducers on the suction line.
