You asked why the casing is called an involute. The answer is because it is not called that, and only so called in error.

The casing shape is called a volute which means a spiral. There is no "in" in volute!

word "involute" comes in Gear profile...

Actually, Manjunatha k has it exactly backward. The gear form comes from the geometric curve called an involute, not the other way around!

Because its casing is in from  of involute because constant velocity  required to maintain.

so casing is make in the form of involute.

 

Saurabh, you evidently did not read what I wrote earlier. The pump casing is a VOLUTE, not an INVOLUTE.

Please people, read what has already been said!!

how can we design centrifugal pump based on given parameters?

Pressur-6-7 bar,flow rate-220-250 liter per min,crank rotation-9000-10,000rpm (pump diameter if required-200mm with 50mm bilateral tolerance) and also ther is some back pressure at entrance of fluid of density 1480 kg/m^3
