Model VSF-55 & VSF-55-XL Delco Vacuums

The first thing I notice is the XL requires a 230 volt supply...can you find that in the subject garages?

If you're going to recycle the water, detergents aren't a good idea. Any foam may create erratic operation. The foam can lift the float on the pump out too early, foam can get past the check ball at the top and get into the vac.
 
Not an expert, but here goes

If you are planning instantaneous grey water recovery suds will be a bigger problem, you may need to use a low suds formula in those tight areas of the garage (I have seen the suds from your standard formula, its major).

If you are using gravity flow, you may continue to use your formula to do the cleaning, then apply a de-foaming agent to the grey water while on its way to the vac boom and that should work.

As for the vac, they do pump out under vacuum
 
You already use a large hydraulic system on your rigs, right?
I would add another hydraulic motor on a switch and drive one of the larger twin lobe positive displacement vacuum pumps drawing suction through a separator (with a float shut off) that drops it through a bag filter in a steel drum. From there pump it through your finer filter and polishing stages to whatever tank you choose (collection or re-use).

That is very similar to what my second truck will be after this takes off.

You will need to keep plenty of defoamer on hand, if you are going to be using vacuum recovery equipment. Foam build up inside your vacuum hoses can create a lot of problems. You should also ask questions such as, how will the intake of 200+ degree water affect the blower and pump out.

Bunn I would think that by the time the water gets sucked up and makes it back to the pump it shouldnt be any hotter than 150 or so.
 
All great suggestions !!!


1. We are planning to use a defoamer to control the subs, though we prefer not to. We have used them in the past.

2. We also believe that the water will cool enough by the time it gets down to the lower floors.

3. Hydraulics would not be a problem, however, that rig would be on the top floors ( 6th or 7th floor), this vacuum would be at the stairs or emergency exits on the bottom floors. Our filter is set at the lowest point of the garage. Vacuum would be setup close (100 to 350 ft) from the filters location. With that said, the Vacuum unit on the top floor, would be to far away from the filter for a vacuum set up. These small vac will be positioned throughout the garage to " Plug Up The Leaks " ( Problem areas ) in a Multi Level garage.

As far as the 220, we have 240 setup on the rig already at 50 amps. ( 20 Kw Kubota Diesel Generator)

4. The other thing we have noticed is that the suds tend to decrease after it is emulsified with the oil. There are still suds, just not as much. We believe that the mixture of oil with the high alkaline detergent has a great deal to do with the sud reduction.

I know that these Vacs will need some attention and that I will need to devote a man to their functionability.

What I am concerned about is the Vacuum itself. For a portable Vac... is this a well made...high quality vac or is there something out there that is better?

Your thoughts?
 
You can get a vac head at Grainger for less. I would worry about their duty-cycle. It seems that if the cycle rating is not right, under heavy use you will go through motors like no tomorrow.
 
Ruwac has always impressed me as having the real good electric vacuum heads. That and Industrial Air Solutions has a nice brushless one as well. I'm not totally up to date on their product line, but I think you would have to retrofit the pump out feature on either of them.
