Goliath flood pump
« on: March 03, 2010, 02:42:03 PM »
I recently purchased the Goliath flood pump from Steam-brite.
This vac is configured as two parallel banks. Each bank has two dual stage vacs in series.
 
Did a t/g job the other day and my helper said is wasnt pulling much of a vacuum.
I ordered a vac gauge calibrated in inches of water to check it out.
At the hose barb where I connect my hose, with all 4 vacs running I measured 100"
of lift. This was way less than the advertised 170" inches of lift.

I troubleshot the vac and measured the lift of all vacs independently. 3 were at 85" and one
was at 50" inches.  One bank measured greater than 160 inches. The other bank measured 70 inches.

These vacs are spec'd at 85" inches each and they advertise 170" when two are in series.

I think I have lost a vac already. Hopefully when this is running right I get 170" at
the hose connector. I know some people are interested in the machine so I wanted to
let you guys know about this.

Thanks for posting that.

Did you contact Steambrite yet?

I'm going to assume that all filters are clean?

What brand vac motor?

Yes, I contacted Steam-brite and talked to Donald, good guy. Who put me in touch
with Alan in California. Alan told me to remove the vac and check the gasket and
anything else that doesnt look right.

After removing the vac I saw a thick gasket on the bottom of the vac  that
was kinked and way out of round. Fixed it the best I could and now I get 160" of lift at
the hose connector. That fixed the problem.

Steam-brite is sending me  a new gasket for that vac.

I didnt know steam-brite had a forum.
I am happy with their customer service AND the Goliath  :)

if i am not mistaken, the goliath houses the german made domel vac motors?
they are configured in a way to get as balanced a performance as possible in the lift and cfm department.
that figure should be 165-180"lift/200cfm's.


with 4 vac motors running, vibration will sometimes loosen internal hose connections.
it is wise to periodically check the "series hoses"!

fyi..............

when vac motors are set in series, the 2nd vac motor will only pull at 65% the rating of the 1rst motor.
in other words, if the 1rst vac is rated at 100" lift, the 2nd is pulling 65" lift. therefore giving you a total of 165" lift, not 200".
so in the case above, the 1rst vac is 85" lift, the 2nd will be about 55"lift, for a total of 140"lift.

i know 140" lift sounds low but when coupled with high cfm, it is a very good performer!!

don cook is a real good guy, and so is kenny ware, don cooks sidekick over at steambrite.
2 straight shooters who will help any way they can!

Micky the vacs are maxvacs model #p0932std .

Thanks for that Micky, yes it doesnt add up like simple math.
I dont know too much about vacs but I did find out while troubleshooting
yesterday that they do interact with each other.
I think about CFM, inches H20 like current & voltage in an electrical circuit.
I dont know what is the best for sucking water off of a floor though.
I know I need both but how much of each I dunno.

Found another problem. The secondary vacuums which are piped to the waste
tank is supposed to have a check valve in the pvc pipe so that you can just run the
primary vacs and not suck air thought the secondary pvc pipe.

Found that it was missing by testing at the hose barb with just the primaries on.
Jamaco is the manufacturer is sending me a replacement
PVC pipe with the check valve.

I'm a little miffed about this now.

I asked if the vac is tested to a spec before its sent out and was told it was but these
problems did not happen in the field and there is no way it tested good to a cfm or inches of
water test.

Lesson learned always have a way to test your stuff.

the maxvacs must be the new motors that just hit the extraction scene. time will tell if they have the longevity of a domel motor.

sorry to hear about yet, another deal to get miffed about.
just goes to show that even in a simple machine like goliath, "spit happens"!


as everyone knows, or should know, cfm's and lift are equally important parts in extraction however, one must understand that lift is the muscle that pulls water from carpet fibers, bare floors, flooded basements, etc.............it is the first part of the equation!

cfm is the movement of air which is created after lift has done its job. cfm is the "release" of that muscle into "flow" or "velocity"!!

in the case of the goliath, or machines like it, the goal is to have as equal amount of both as possible so there is maximum pull and flow!!!

I sure I will be happy with it when I get the parts back in it.
At least I know how it works and how to fix it if necessary.
I think Donald or Alan (from jaaco) said they were new type of vacs.
We'll see.

I put my 2 ridgid vac in series, one a 2-stage and one single stage (80 & 50 inches respectively)
and the total was (like you said) less than the sum of both.

How long is the warranty?

 Keep good records of all your conversations, with whom, date time, number, etc.

Will they give you money for doing field testing for them?

They should do something. I spent some time going through the
vac troubleshooting it.  I would think they would test it before shipping it. After all, it's $2000 item.
It would take them 5 minutes to test for inches of water, first one bank, then the other, then
both. That alone would of caught the problems with it.

Any updates on the Goliath/Water Otter combo for tile cleaning? Did you ever get heat? Any problems tripping breaker? Are you able to clean carpet with that combo? Any regrets?
