Hello, I have a few questions about my unit. First off my PW is a husqvarna 2.8gpm 3100psi , direct drive with an axial cam pump. I know it's small compared to what most of you guys have here. Pressure washing is just a part time job/ business I'm trying to get started. I'm only doing residential stuff and maybe a few "small" commercial stuff but nothing major. After I learn more and upgrade my equipment I will eventually start doing more.

So here are my questions, can I run a buffer tank with this unit?I've been looking at a few surface cleaners, but I haven't found any that match the specs of my unit. Been reading here on the forum about changing the tips to achieve the proper pressure and gpm to match the PW. Can someone recommend me a SC?

Thanks Fredrick,
 
I think you are going to have real issues running a surface cleaner properly (let alone efficiently enough to make $) with that gpm. Personally I'd say an entry level (I.e. 4gpm 3500psi or better) commercial machine should be your first investment before thinking about a surface cleaner. Even if you do get your current machine set up to clean what you want to... chances are it won't last too long once it sees some real action.

+1, also most direct drive systems will not pull from a buffer tank.

Good luck!

Both of my direct drives pull from a buffer. My startup unit (now backup or addition unit) is a Simpson 2.4 gpm/3000 psi (model msv3024). And my current main unit has a 4gpm/3000 psi cat 66dx that pulls nicely from a buffer. Both push my 20" sc as well. of course the 4 gpm is better, but with the 2.4 it worked. slower, but it worked.

All my cat pumps pulled well. Love me some cat pumps!

I would probably end up cutting my wrists if I had to run a surface cleaner with 2.4gpm. I get irritated as it is running it at 4gpm. It was fun when I started but near the end of the summer it got old.
 
An axial cam pump is almost completely hopeless at drawing from a tank. They don't develop vacuum well at all. If you HAVE to run it off a tank, I'd suggest a 4 gpm, 12 volt demand pump in the suction line to feed it.
 
Thanks for the great advice Russ.

What we need is a sticky post up at the top of one of the forums of all the known pumps that are direct drive that will pull from a tank without problems, this way guys can see the list and know if they will have good luck or know what pumps not to purchase when using a tank on their truck or trailer.
 
I would rather buy an UDOR, General or AR pump before I bought a Cat pump, you can maintain these more economically from what I have seen.
