Folks,
The duplex type of pump e.g. Worthington type will certainly pump using water instead of steam. I had the job many years ago of pumping out a flooded forward pump room on a tanker which some idiot had allowed to fill with about a twenty foot head of sea water.
The little Thomas Lamont bilge pump was of course at the bottom of all this but managed very slowly to empty the space, It was of course supplied with steam but after 500 feet of unlagged steam pipe along the deck and then going down through the flooded space, I dare say it was pretty well water at least at first. Admitted the pumps discharge head was not great.
Incidentally the steam launch Shamrock on Windermere has the steam supply to her two Penberthy injectors fed via a dip tube which stops at the high water level mark therefore you cannot overfill the boiler as they just stop working at this level.
Regards
Jack
