Useful information on centrifugal pumps

Useful information on centrifugal pumps What is a centrifugal pump? A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller

Does Impeller Affect NPSHR? OAKTrust Home

Also, a change in impeller diameter does not generally affect NPSHR, because cavitation occurs at the impeller inlet. Test results have proven that this assumption is not true for some high specific speed pumps. High specific speed pumps are more sensitive to the effects of variation because of relatively shorter impeller blade lengths.
