Thanks.

My heavens, was he asked that?
It is a pump run off the old steam recip engines crossheads.
They are designed to to handle air and condensate from a condensor.
I've seen one 25 years ago in a museum.
oh God, I just realized it is more like 28 years :shock:

Thanks, JK, I'll pass this on. I think it may be time to update some of the questions.

Yes,
The only experence I have with steam are TA's, and cargo pumps, but never propulsion.
Most Systems I am looking at these days are Hot water or thermal oil.

My steam experience is the old up and downers. A long time ago.
