Gx390 best pump to use for commercial flat surface cleaning

im looking for the best budget pump for flat surface cleaning using the gx390

The unicorns are on aisle 3.


Well, you can get a 4gpm/4k psi direct drive unit fairly cheaply but it’s not the best for surface cleaning as all that psi will just be wasted. As a minimum you’ll want a 5gpm/2500psi and those aren’t cheap plus it’ll be more of a belt/gear reduction drive pump.

i already have a 5gpm pump, was just wonder about the size flat surface cleaner i should go with for that gpm.

This was your original question. But anyway to answer the second one with a 5gpm you can do a 16" or 19" surface cleaner.

Some people. @dcbrock youre way too helpful to those undeserving. This🤡 has 34 min read time and doesn’t even understand the english language. He thinks a pump is a surface cleaner? And he already has a pump so why does he need a sc?

@dcbrock thank you for all the help brother💪🏾, I didn’t mean to come off like that, you guys are awesome I’m man enough to admit that. Just have a lot of stuff going on didn’t mean to project.

@SWFLWasher my apologies I posted in 2 different forums. I did needed a pump, and I got one, so people were very helpful, I thought this was the group where I asked a straight question about a surface cleaner size. But your completely right, and I admit that as a man.

I just tend to give people a pass sometimes, I was in his shoes five years ago trying to figure all this out after having a long-term career.
