I have a question pertaining to the use of flexible cords in an industrial environment. There is an industrial dry pump that is permanently anchored to the floor that is powered by a flexible cord connected to a disconnect located near the equipment. looking at the power connector on the back of the dry pump, it doesnt look like it can accept flexible conduit to the connector.

So my question is. I know the NEC states that any equipment that is permanently installed should have permanent wiring (i.e. flex conduit or hard conduit), but what about equipment that only accepts flexible cords and is permanently anchored to the floor?

Any thoughts on this would be greatly appreciated.
thanks,
