Hi does anyone know what's the biggest pump  you could can put in a steempro 2000 I've got 150 psi but would like to  put something bigger in there.

i would say 250psi aquatec or 250/300psi pumptec , both for good prices on cleansmart and woodbridge ..

Thanks John I'll look into them.

I put a 220psi on demand pump in which I got from the prochem site.
Was a straight swap for the original 150psi although you can also simplify the plumbing so it isn't re-circulating which allows the on demand function to work.
