impeller wear rings function

[muhammadhaleemghani]

why both wear rings are of different size in double suction pump

 

[Artisi]

How different?

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.)

To make sure you don't install the impeller backwards.

 

[JJPellin]

We have also done this in order to create a stable thrust in a predictable direction. This was done to resolve a chronic problem with axial shuttling. For your pump, it was most likely done so that your mechanics are less likely to install the impeller backwards as 1gibson noted.
