PUMPS inducer question

[garciaf]

My issue is the following
This statament es a suppostion
I have two equual Pumps, But later I decide to modify the suction adding an inducer in one of these pumps,
How the flow would change in these pump.
also if I change the inducer for one bigger, the flow would go up????..
please help

Hi,
Pump inducer has to do with cavitation only !
If you want to increase the flow you need to increase the RPM of the pump or change the impeller .

The flow in the pump with the inducer would increase, but by how much is impossible to say as it depends on the non inducer pressure differential.

My guess is very little difference.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

My experience is that unless you are cavitating or very nearly so then adding an inducer will not change flow.
In some cases it does increase power required slightly.
