Moving forward with our recycling system - for pressure washing I am trying to determine the best way to measure a hoovers capability.

The hoovers I am looking at will be either 240 or 110 or even 3 phase, they will have an auto dump out facility that will recover any water and detritus back to the filtration set up but I need to understand how to measure any vacuums capability.

Is this side of it measured in L/S (lift per second) and if so what is a normal hoovers L/S and what would be a beast of a machine capable of picking up heavy slurry, moss etc.

I am looking on the website of the company that have taken the project on and they have a 240 volt machine capable of 156L/S - is this good or not.

Any vacuum that I choose to do the recovering needs to have a splitter put into the vacuum pipe to recover off two flat surface cleaners.

You guys up here know more about this side than us down there.

Any help ?

Many thanks

If you are looking for capabilities like that you are looking at quite a powerful machine.
176litres/sec is around 330 cu ft/min.
There are several machines that would do this, but would be unlikely to run 2 operators.
Presumably you do not need a spray, like a carpet cleaner, just pickup.
There are several manufacturers such as Nilfisk who make wet pickup machines with a fair sized vac pipe.
This may be what you are looking for but it will only run 1 operator.

Yes I have looked at those machines but as well I know a little about the motor options but not enough to put the L\S and motor options together.

There is a vacuum available that is three motor, combined at 4200 watts - should this be considered, I don't know the lift per second on this one.

I have also spoken to the guys at Predator hawk, see,

http://www.predatorpeople.co.uk/predator_hawk.htm but they have not come back to me. This would be a better option as the additional genny would not be required, being a diesel unit.

 Spotted this wetvac with pumpout  that looks kinda heavy duty ...

 http://www.bigbrute.co.uk/demos/industry/floodman.htm

 
 Most of these industrial wet vacs are basically a canister with two vac motors mounted on top ..
There are too many unknowns to generalize about the lift and airflow for various models ...

You would need to know the type of vac motor used  , the wattage , the number of stages  , and the configuration in which they are connected ie air series or parallel .

I wouldn't suck water up with a Hoover, it voids the warranty

I was talking to your briefly on the 'other channel down below' a while back and you are obviously going ahead with your washwater recovery and filter system development!

Good luck - I think you will be well ahead of the game if you can do it - I still think a truckmount would be better for recovery than electric but you know your market

By the way have you ever been on this website dultmeier - they have a huge range of useful stuff - I bought a Cat pump clutch off them last year so they do know how to export (lots of US companies are not that interested) anyway they produce a cheapish boom recovery system that you could probably replicate if you bought one over initially - here's the link:

Let us know how you get on with the filter system
