What Happens If Centrifugal Pump Is Operated At Excessive Speeds ?

1.	What Happens If Centrifugal Pump Is Operated At Excessive Speeds ?
Answer» When a pump is operated at excessive speeds, the differential pressure DEVELOPED increases and causes a powerful PULSATING vacuum on the underside of the blade tips and each particle of WATER is pulled away from the blade, taking away with it a small particle of metal, producing pitting/grooved effect. Repeated erosive action results in complete honey COMBING and total DESTRUCTION of blade, with resultant loss in pump performance.
