The result was that the pump would seize AOD as the expanding idler gear locked up between No Yes Yes the crescent and rotor gear. The solution was to put in a heated pump head, such that a smaller assisted flow, vertical staged centrifugal, flexible impeller, and gear thermal gradient could be maintained between the rotating parts — VFD, soft-started, or just on/off — each of which was selected of the pump and when they started to expand they wouldn’t impact and used for a specific purpose and application. No one pump does each other.
