Effect of fluctuation of flow in Pump Suction. 2

[123engr]

Dear All,

Please, I would to know the effect of fluid flow fluctuation in pump suction.
What impact does it have on the performance of the pump?

Depending on the pump style and application it could range from no or very little effect to catastrophic failure.



It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Please explain what you mean by fluid flow fluctuation.

Tell us what you are after, it will shorten the time you get answer. I'm going to guess: Are you looking into the need for, or value in suction diffusers or "vane straighteners"?

Next contestant's guess please.

It can cause fluctuations in vibration, and performance of the pump.

What do I win?

You need to be more specific on your questions
there could be be many problems because of fluctuation on the suction
NPSH probelem isone of them which leads to cavitation of pump

but again please be specific on your question

Fluctuation on flow could affect the performance of the mechanical seal.
