A friend of mine hold the patent and the manufacturing rights to the turbine
pump you are referring to. I first saw the pump in a Professional Boat
Builder magazine 10 years ago. These where bolted to the prop shaft and spin
constantly. Since it has no wearing parts it makes a great emergency pump
that is always on standby. He is currently building the pumps in Pascagoula,
MS. These pumps are quite strong and move lots of volume.
As for shaft RPM I have no idea what is needed but I can find out. Maybe I
can list a link to his website sometime in the next week or so. He
currently builds most of them for the Oil field service.

The pumps that I supplied the rpm data for, appear to be made in Sweden.
Perhaps there are two firms making them?
