Rotovac New motors

[Ymetimme]

New minds bring new technology. I think anythings possible from any of these manufactured motors...I'd like to think a dog would never care to mount a cat from behind but I've seen that happen too

Everything I've bought some rotovac in the past has worked as stated
It would be too much of a gamble for them to not come out with a product that does what they say
After all I was the biggest skeptic of the LX motors and whereas I don't find them to be as incredible and Earth changing if people claim are pretty darn awesome
Between the original 6.6 & 8.4 & LX & ZX we are in a whole new world of vacuum motors

I spoke to Jeff at rotovac a few hrs ago and stated he will have them in my hands in less than a week. Ordering 3 to put in series inside this steamway 900 in the morning...excited to see how this turns out

Please post how it goes I'm excited to hear your findings

I held off on ordering some till I get my CfX with those motors them
but I'll probably break down and call and order some vac motors anyways lol

Have a feeling 3 will be rocking

Finally got them ordered today...swear not enuf hrs in a day around here...said they should be delivered by Friday. I'll post pics and theres an hg meter that came stick on steamway so I'll know pretty fast what its pulling and lost pics once they're installed...3 in series should have a bit of both bite and bark

Hoping this vac configuration does a better job than Jenna Jameson

All looks really good so far. 17 hg w all 3 turned on... 15 hg with 2...all 3 may go higher but afraid these will crack or implode this fiberglass tank.

Imploding fiberglass tanks; hope that doesn't happen to you!.

That reminds me of way back in the late 70's, early 80's we were doing a demonstration with one of our high performance fiberglass machines with a couple 7.2 vac motors installed.

After we put the petal to the metal so to speak (wand sealed down extracting)----BOOM! Scared the heck out of us; sounded like a bomb went off! You wouldn't believe it unless it happens to you!!

Fiberglass has no flexability and that can be a real problem.

Best of luck.

My entire goal was to be able to run 100 feet of vac hose w out losing any suction and hopefully get some better dry times. But even if I dont get better dry times...just being able to run 100 ft of vac hose is enough for me until I can set aside money for the Jag 8.4. 2 motors are pulling 15 hg. 3 over 17. Is 15 hg good enough to successfully run 100 ft without issues...not popping breakers...at least not in my own house on 3 cords however on jobsites I'll still need to find a 5th to run water otter

 

[DrummerTW]

4th I meant

higher cfm with 2 inch hose will give you longer hose runs not lift.

 

[DrummerTW]

Would it be easier to put in a 2nd stack and run the vacs separately

 

[DrummerTW]

I can put one on in about 5 min

The major reason the Jag is able to run such long runs is not because of its lift 10hg
The reason is It has more than cfm's 280

My suggestion is to reconfigure your vacuum motors to have 2 in parallel and one followed in series through a y
This will put you somewhere around 16 in of lift with 230/ 240 CFM
If you are currently getting 17 HG with them all in series you are probably sacrificing a significant amount of CFM through the final stages of the last vacuum motor
Remember vacuum motors are centrifugal compressors not just blowers you compress already compressed air you start losing efficiency of flow.

by the way I would probably consider setting up just two of the vacuum motors in series that would probably be the most ideal

You're incredibly helpful my friend

 

[Ymetimme]

You're incredibly helpful my friend

Thank you I try to be

 

[DrummerTW]

If I setup 2 in series...and the 3rd to a y.. will that make it possible to run just the 2 in series on jobs that dont have sufficient outlets...and would it be better to run the 3rd vac to it's own stack

What I would suggest is making two of the vacuum motors in parallel

Yes you will lose lift
But you gain an extreme amount of cfm's
This board is full of people that love lift
But the fact is cfm's are critical at maintaining lift over a long run

For example and air conditioning recovery pump can hit 23 hg but it has 5 cfm's
It would take forever for it to pull enough vacuum to use for cleaning

The nice thing about the idea of running a third on its own stack is the fact that you could cap it off for general use and run the other two in series

I still think just two of those motors are plenty of power rather in series or in parallel

Remember is something to play with find what works best for you


I will show some drawings in order to help you understand it has to be pretty awesome though compared to what it was

Man put my 6.6 in front of my two 8.4s today for a long hose run and it’s crazy how much it impresses me. I can’t imagine how anyone can preach you can go faster with a TM. I was bogeying

A human being can only go so fast!!!

Yup, working smarter works for me. Did I make $1000 today? Nope. One job $524.00 a few hrs, I’m happy as a clam. I could of done another today but naw, there’s another day. Starting to get nice being able to not have to chase every buck killing myself.
