HOW THE CENTRIFUGAL PUMP CHANGES WITH USE OF INDUCER?

A well phrased question has answers in itself!!!

 

[shashankTurbomachine]

I have read that use of inducer results in:


[li]Narrower operating range (20%-80% BEP )[/li]
[li]back pull out design is not possible[/li]
[li]NPSHr is reduced by 35-50%[/li]
[li]Inducer cant be used with open impeller[/li]
[li]How is inducer curve differ from conventional performance curve[/li]
[/ol]

It would be good to know the reasonability of all of above.

How about doing some research on each subject yourself, does wonders for the learning curve.

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.)

i have also came to know that use of inducer is actually not accurate as this will reduce NPSHr at a particular speed only and rest speed it will have high NPSHR.

Kindly thro some light on it.

The details of all of this are subject to each pump vendor and type of inducer.

An inducer can reduce NPSHR.

That's it.

All the rest is details which can be provided by the particular vendor.

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