cavitation problem

[smain06]

I suppose that I have cavitation problem in the miltistage horozontal pump i want to know how to eliminate this cavitation and how to improve the performance for this pump
thank you for your help.

If it is really cavitation, you can resolve via :
a. increase the system pressure ( e.g. RO )
b. reduce the fluid temp below the fluid boiling point at the given pressure.

a and/or b above will eliminate the formation of bubbles which later lead to cavitation on the collapse of these bubbles.

Good luck !
