Thanks for the responses. In our application the pump runs continuously at a fixed speed and goes into a bypass when the vacuum supply is met (which is not often). I do not believe we have much, if any variation in the load. We have gone through several ideas to reduce the load/operation...
I have a vacuum system with a 75 HP pump running on 480 with a SF of 1.15. FLA is 86.
The motor is running overloaded at/above the service factor load (~99-100+). We had a contractor look at the pump and give us three recommendations:
Rewind the motor to a 1.25 SF
Buy a new motor with a 1.25...
