hi guys,could anyone tell me the max hose run i could use with a commanche 2 stage twin vac and 120 psi pump please..thanks

you have 155" lift and about 90 cfm  ....    thats quite low really

I'd say 25 ft max

A cheap upgrade would be two 1500w £55 three stages from jackson spares on ebay .
that would give u 220" lift and 100 cfm .

or mount the three stages in parallel for 200cfm and 137" lift  , most would agree this is good for up to 75 ft.

thanks john, an upgrade seems the way to go, would it be easy to do..

 series should be a matter of just swapping in the three stage motors ...
but u would need to have alook at the original motors and see if you need to get vas with or with out the tube connector fitted . ( tube at bottom of pic )

I think one vac is mounted on a manifold directly to the tank bottom , and the other is vac is connected to the first via a short hose .  so one vac may have no tube and the other has . You can always cut the tube off anyway , but if u pm the seller he will send u one without .

Parallel might be a little tricker as u will have to fitt a Y splitter to the vacs and connect to the waste tank stack pipe ....  would need to see the internals really , but should be easy enough .

For the amount of ar$eing around that would be required and good money thrown after bad, wouldn't it be a better idea to buy a more capable machine?

I have one in our workshop at the moment.

If I remember tomorrow I will chuck up a couple of pics.

 Wait for it! I sense the word truckmount coming on.

These are the 2 stage vacs fitted to the machine. They dont have the tubes on them and mount with a gasket onto the bracket fitted.

Changing to 3 stage motors would mean having to fabricate another bracket or modify the current one along with mounting posts etc. Looks like a lot of messing around for little return.
