---GO GET 'EM JOHNNY PELLIN !!! --- A STAR FOR YOU ----
Guessing games can be excused by newbies,
But, in recent years, I have detected a distinct Mid-Eastern attitude of leaving out important information .... on purpose !!
My Turn ???!!! ....... Why Thank You !!! ..... I can give you a few Pellin Maybes !!!
Maybe the pump fell off the truck as it was being delivered and bent the shaft and casing
Maybe you should call in a pump specialist who will perform both a shaft runout measurement and a vibration survey at different pump speeds
Maybe you could tell us how old the pump is, the age and type of mechanical seal and the amount of permitted leakage.
Maybe you could perform an evaluation.... does the maximum leakage occur at the maximum vibration speed ?
Maybe ... maybe ..... maybe....
