i dont see anything wrong with pumping almost boiling water at 150psi.. . . . . .it will be enclosed just in case.
wana have a coffee maker in my shop and there are no way i'll put a nice machine out there. easiest way i found to make something acceptable is to pump hot water trough a portafilter, its also very versatile and adjustable to go that way.
i just can't find the pump, and all the information i find about the procon are quite unsure.

A pump needs to be designed with components that are able to be serviceable at those temps. Most pumps are not so designed but may be used in such service, for as long as they last.
If you just start shopping at Goodwill and similar stores, it will not be long until you find a pump driven machine for about twenty bucks, no high quality machine need be purchased and the work will be done. Then again, if the point is to make it yourself then that is a different thing.
