Answer : The interval between overhauls will vary according to the product being handled and should be based on total operating time.
To a large degree the rate of wear for an application will be ascertained by practical experience.
It is the responsibility of the user to determine the time between inspections (recommendation: for non-abrasive materials every 6 months).
Wear will be influenced by abrasiveness of product, pressure difference over rotor, temperature etc.
