Utter ********. Cavitation is a problem of _low_ pressure in pumps,
sufficient to form bubbles (i.e. "cavities"). The one thing we know
about a boiler feedwater pump of any form is that it has to work at
around boiler pressure. Whilst the Giffard injector stops working with
hot water, heat isn't a big problem for pumps.
