Surface cleaner

I have a 24inch stainless steel surface cleaner. I recently bought a high pressure T with three couplers and a short high pressure hose to join both of my machines together into one hose. I changed out my nozzles on the cleaner to three 3.5gpm nozzles. Totalling 10.5gpm @ 4000psi. The difference is huge!

10.5 @ 4000, that's good flow and pressure!

It is sick. Without the concrete cleaner, with a single wand and a 10gpm nozzle it damn near knocks you down!

The pressure I haven't measured exactly, my gauge busted on me. The machines I have are 20hp 5.5gpm @ 4000psi and 13hp 5.0gpm @ 4000psi. The 13hp doesn't quite push it at maximum. The pump requires a 13.7hp engine, so I'm bogging it down slightly. Probably runs around 3200psi. With both machines going into 200ft of 3/8 hose there is more pressure loss probably with 10.5 gallons going through it. I bet 1/2 hose would make a big difference.

My guess is I'm actually pushing 10.5 @ 3200psi.

We run a single 8 @ 3000 into a 36" (ww) and it does a great job
 
I have Big Guy on a 8 gpm , got it in Aug, I love the 8gpm when doing concrete, its amazing how much quicker it is compared to 5.6

I also have another Big Guy on a 5.6 and a Classic on another 5.6


I remember a long time ago doing residential driveways with a wand, then I thought I was really something when I found out about the Roto Nozzles. Sure wish I knew about these BB's before so I didnt have to go through the school of hard knocks. Man a driveway with a wand, that was always fun on the back


I really like the Big Guys

Jeff, do you have a high pressure T ? You can join your machines together to make 11gpm or 8 + 5.6 = 13.6gpm.

Mike,

No I dont, The Big Guys are rated up to 10 GPM. I'm sure you could get around that with changing tip size. But we have 3 guys cleaning so thats why we have the 3 surface cleaners. I plan on getting another machine this year. I might have Bob from Pressure Tek make me a 10gpm machine or just get another 8gpm

Id like to try out more GPM , 8gpm is great I can only imagine more GPM than that

where did you buy the "T" from ???
 
Cool, if you have four machines and two concrete cleaners, and you bought two high pressure T's, with couplers, two short high pressure hoses, new nozzles for your concrete cleaner, you will have upgraded to two monster 11gpm concrete cleaners. Eliminates the need for two guys. Your help will be so mad if you do this! LOL!

A local plumbing store, or ask Paul or Bob if these are rated for high pressure.

Russ, what kind of machines are you running?

I was thinking of buying another concrete cleaner, now I don't need to.

Just join your machines together. Now I can clean twice as fast, eliminates the cost of more equipment and labor.

You should try it with a 36", that would make concrete cleaning fun!

They do make a difference, I am thinking about getting a 10-12gpm for it next. It is heavy so we keep our classic for rear patios, etc... The path it cuts is impressive and they are built well.

What type unloaders are you using?
 
Mike Sullivan said:
AL 607 on both.

What kind of engine are you pushing your 8gpm @3000?

You have any other machines?

Tsf2021, 24hp honda on a gearbox. 3 - 13 honda/gearbox/cat, 2 - 4.5 @3500 & 1 - 5 @ 3000

All are on "flow sensitive" unloaders.

Wow, that 24 is a beast!

After I hooked both of my machines together on my concrete cleaner and changed the nozzles it is so much stronger it lifts the machine more making it feel lighter and easier to move around.

That would be awesome if you hooked up your 8gpm and 5gpm together to make 13gpm. You would fly with that BIG GUY!
