One thing it does is cool the bearings; if liquid did not circulate, the bearings would heat up. If the fluid has lubricating qualities, it will also provide lubrication to the bearings.

Thanks Tornado for your inputs...I am sorry coz I am only newbie..Godbless..Peace...

Glad to help, and welcome to CR4.

(Another thing you might see, which could look roughly similar, is an equalizing tube for decreasing axial forces on an impeller; sometimes called a "balance line".) As you gain more exposure to pump designs, you will see a number of arrangements for various purposes.
