Vacuum Pump not proper functionally

[mainul2463]

Recently impeller of vacuum pump is broken of an autoclave (chamber capacity 550 liters), Materials of impeller seem to be gunmetal therefore i make the impeller as per sample by gunmetal. But vacuum performance is not good. i require 115 mbar but only get 500 m bar
i have checked the vacuum seal , leakage around the piping

If you made the part it is probably not to correct design / dimensions. Suggest you purchase a genuine part.

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.)

Is there a reason you are ignoring Artisi's suggestion?? Seems like look advice to me

If you're determined not to follow Artisi's advice and buy a new OEM impeller, it would be easier for you to design a new complete pump.
