Pump upgrade?

Good morning all.

I have a Simpson ps3228, GX200 with AAA pump 2.5 gpm. From what I have been able to find the 4 gpm pump should mount up, but is it possible to simply swap the pump to get better flow so I can use better surface cleaners?

What size motor? You’re going to severely limit yourself on max psi by increasing flow.

ITs the Honda GX200 5.5 hp 3600rpm

You can’t surface clean with 1500 psi. Time to upgrade machines

Can you give me a link to that calculator? I tried going to barens.com and it wont let me reach it.

It is my understanding that it isn’t going to work out the way you’d hope for.

nvm, infinity already addressed it.

Thank you, I appreciate your help.
