390cc pump suggestions

What the best pump to put on this?

Cleaning concrete and interlocking

I’m thinking 6-8 gpm and 3600 psi




Ok hold on. 6-8gpm and 3500psi won’t work on a gx390. You can get a 2500/5.5 but that’s pushing it.

What does this mean?

Probably pavers.

What is this for a business?

I’d put this pump on it if you want to do concrete and downstreaming for house washing.

Should get between 2500-3k for flatwork which is plenty and with 5gpm you’ll be able to rinse faster than with a 4/4
