Can a pump equipped with a mechanical seal be rotated manually when it has not been filled with fluid?
Of course, with some pumps, even after filling them with liquid, it may not be possible to turn them by hand.
Yes, there are no special requirements for this type of pump; however, if there is a separate lubricating oil station, it must be activated before starting the pump by turning it manually
Basically, it can be turned by hand, unless the manufacturer has specific requirements
Sure, it’s better to keep it on if there’s flushing water available
It is recommended to turn the shaft under the manufacturer’s guidance
It depends on the flushing method of the mechanical seal; if it is self-flushing, the pump should be filled with fluid first before the shaft is rotated, otherwise the mechanical seal will grind dry
