What about this spinner used for cleaning concrete? Anybody have any experience/feedback on it?
I can pick a used one up for about $300.00

Thanks,

they are used to provide an even clean to large areas. if you have powerwashed before you would have noticed how streaky a wand leaves the surface. with a suface washer with good pressure and good flow will provide a constant and "more" even clean appearence than the wand. also by design the surface washer will increase productivity and most of the time decrease energy needed or used to cleanthe same amount of area.

James;

A "spinner" that size will require more GPM than nearly all TM's can deliver.

I would estimate at least 6.5 GPM for efficient cleaning.

I remember seeing a few videos on youtube showing them in action if you search "pressure washing" +concrete or +surface.

Larry is right, the bigger they get, the more GPM needed to be efficient. At 28 inches, that's about as big as they come.
I have only seen the water broom option on the larger ones.

Yea, but Larry - I'm sure you could hook me up with a pump that would keep up with this spinner. Right?

My question would be, "Could I modify a pump that size to fit on my Powermatic?" Or, would I have to set it up with as a completely different unit?

Thanks for the input,
James

Considering that this is the minimum size pump required to run a tool like that

I don't think your going to find a truckmount that will run that size of pump and a postivie displacement blower at the same time with out custom building one with atleast 70 plus horsepower

There is a reason guys that do concrete cleaning use rigs like these:

All the power of the engine goes towards the pump, no energy wasted on a blower for vacuum.

David makes a good point in that you need some hp to run both a blower and a pump at capacity but you don't need high hg's on concrete and you don't need 5000psi. 4000psi and alot of btu's will do almost any cleaning job. I THINK if you kept the hg's down and used 3-4k psi then you could probably do it with a decent size machine, maybe 35-40hp.

The website info says:
Max Rating 4000
PSI / 10 GPM / 250 F.

I always understood that most (not all, but most) concrete cleaning was done @ or below 3000 psi. But, it doesn't matter. There's not much of a market for concrete cleaning in my market and I'm not going to spend more than a few hundred "IF" I were planning on getting into it. Thanks for helping me make a decision.

Power washing is more about the GPM, not the PSI.

Think about moving 1 gallon of water, in one minute, at 3000 PSI.

Now think about moving 8 gallons of water, in one minute, at 3000 PSI.

A 4 GPM machine can cost 1,000 dollars, but a 8 gpm machine can run you 6-8 grand. Twice the GPM, but 6-8 times the price.

Its being able to move a high VOLUME of water that translates into faster cleaning.
