Water pump tank empty

[Carbon18]

How much can water pump take running before it gets burned out with no water in tank? Daughter tried to run faucets etc when fresh tank was empty. I saw switch was on when returning to rv . Will pump even run with no water in tank?

One of the "features" of the flo-jet pump in my trailer is "dry running", not sure for how long... there is no specification for that.

I know it has been run dry at least once and still works.

Put water in the tank and see what happens?
