Grease guns are, some of them, capable of at least. hundreds of psi.
I happen to own a 0-5000 psi gauge. Bought it to check tractor
hydraulic systems. I forget just what a grease gun pumped it up to, but
it was a lot.
There is a reverse osmosis watermaker intended for liferaft use, with
a hand pump, and RO takes hundreds of psi. That is what you want, if
you actually need high pressure.

How interesting! Sure enough, a grease gun can usually put up 1000's
of psi. and a low volume RO with such a hand pump seems like a
reasonably economic proposition. Wonder how much they cost.
Must take a look!
