Friction of the mechanical seal faces running together without lubrication or the shaft packing running against the shaft without cooling by water seepage are the result of pumps running dry. Impeller clearances are usually wide enough that the impeller and volute aren't damaged when dry running occurs, but if the pump uses the fluid media to maintain a balance or if tolerances are extremely tight and there is contact with the impeller and volute then galling, damaging, and possibly seizing the impeller could happen.

How do 100 story buildings get water to the top floor?
Water is moved to the top floors of high buildings via pumps, which lift the water in stages. We may also see check valves, which prevent the water from flowing back down the pipes. The pumps will be placed at intervals up through the building so that one pump doesn't have to develop all the pressure necessary to lift the water all the way to the top. The lifting of the water is done in stages with pumps.
