Truckmount 55 Gallon Water Restoration Test

[Larry Cobb]

Set up a 55 Gallon Flood Extraction Test Today.

Dynachem 534 Truckmount - 34HP with #4MR Blower @ factory specs.

50 Ft. of 2" Vac Hose into a full 55 gal. drum of water @ 3080 RPM.

Vacuum during test was at 15.5" at the TM gauge.

Time til Drum was Empty = 36 Seconds.

Engine RPM Drop was only 2% for the 34HP Kohler indicating light loading.

Not a drop of water was noticed on the blower exhaust despite the turbulence.

Note : TM's with only 13" hg. max will lose in this testing (Sorry Mikey )

i can beat your tm by tipping the 55 gallon drum over, empties out in about 5 seconds.

 

[Larry Cobb]

That is exactly how some water damage occurs . . .

 

[Scott S.]

who would be sucking out 55 gallon drums of water larry? lift doesnt mean a thing if there isnt airflow to carry the water away.

 

[Desk Jockey]

Not that the numbers are not impressive BUT 50 foot is not realistic. Who can get that close to a home with 50-feet???

But then the test really doesn't prove much either. If there is more than 1-inch of standing water a TM is not the best approach. Submersible is your best option, why damage your TM unnecessarily. We only setup the TM after the drain has been cleared or after the submersible has lowered the level down to an inch.

I really like the design of that and would consider it Larry if. .... it was stainless steel. ....

Wouldn't you use a trash pump in that case?

When some calls and says they have standing water my first suggestion is call a sewer or drain cleaner. Its much more cost effective for them to let the water just go down the drain once its cleared. If they can't get anyone out I do suggest a submersible or trash pump from the rental store.

Trash pumps work great at removing a large volume of water fast. Unfortunately nobody likes to pay us to baby sit a submersible or trash pump. Or if they do pay its not what we could have earned working somewhere else.

We don't show up until they have the water down to carpet level. It saves them money and saves us time.

you mean to tell me that the clients dont put the flood water in 55 gallon drums for you to suck up with your machine? how rude.

 

[Art Kelley]

Not sure what this drum test proves. How does the Dynachem 534 perform with a rotary extractor for thousands of hours of operation as compared to a direct drive machine? That would be real world to me.

 

[Larry Cobb]

This TM stress test was to check Engine RPM drop, V-Belt design and Recovery Tank efficiency for a client who has to vac liquid spills quickly into a recovery tank. They were cleaning up after Ebola last summer for the local government.

Art; Our TM's last 15 to 20 years and thru 3 to 4 vans.
How many PTO's are still running after that length of time ?

We also have done the same test with several "flood extractors" for a large flood restorer.
The best portable flood extractor picked up AND pumped out 55 gal in 90 seconds.
It was a Mytee Flood Hog.

did ya try it with 25-ft of hose? 15--feet? 10-feet?

You beat me to it

if the blower was not reduced to 2 1/2 you can cut those 36 seconds in half

 

[Mike Draper]

You were running the engine at 3,080 rpm? What speed was the blower spinning? What is the max rpm of the blower?

We carry the Nifisk Attix that is a single cord unit that picks up and pumps out at a gallon a second

My 2003 pro 1200 is running great with over 6000 hours and never a breakdown. I think I changed the belts once.

 

[Larry Cobb]

Kevin ;
I'm sure you have kept your Van in good condition.

It's just after 12 years of active duty . . .

most vans look pretty ragged.

Won't the series configuration have a huge performance drop off past 50 feet? Say at 100?

 

[Mike Draper]

@Larry Cobb did you see my question?

 

[Desk Jockey]

@Larry Cobb did you see my question?

If its too controversial Larry won't respond.

Probably a smart move on his part. It doesn't do him any good to get into a fight over nothing.

 

[Mike Draper]

it didnt cross my mind that my question would be controversial. I'm just curious

 

[Desk Jockey]

oops I didn't even look at your question.

 

[Larry Cobb]

You were running the engine at 3,080 rpm? What speed was the blower spinning? What is the max rpm of the blower?

Blower was operating @ ~2800 RPM .
Maximum RPM for the blower is 3600 RPM.

 

[Larry Cobb]

Won't the series configuration have a huge performance drop off past 50 feet? Say at 100?

Series vac motors in the Flood Hog have more LIFT,

which you will need for longer hose lengths.

 

[Scott S.]

so ebola, how again is it contained and safe to suck up and vent to the outside world in microscopic water particles?

While yall are just being asses and stinking ones at that, I found this test useful in some situations we have encountered.

We have some older houses here where the living room is recessed down about 8-10 inches by design (don't ask me why).

When the house has a slab leak the living room fills up with water first till it crests into the rest of the house (seen it twice), as we are in Texas and have no basements, we normally don't carry around sump or trash pumps on the truck and the particular job we were on was about 50 minutes away from the shop.

So we just craked the machine on and let it go to town, it took a few minutes before the vortex shutdown because it was full, but it only took two shutdowns before we had removed all but the puddles water from the living room.

Even if we use a sump or submersible we still have to extract 1 or 2 inches of standing water and there is no way around it.

But I do understand Chavez position as he uses a butler and he can't extract that volume of water.

Small machine complex, it sucks, I know, I used to have it.

That's what we are talking about Michael!! All vacuums suck, that's what they are supposed to do!!!

 

[Desk Jockey]

Right? You use a short hose? 50-feet on a job?

we normally don't carry around sump or trash pumps on the truck

If they build homes with sunken living rooms why do you not have one on the truck. We always carry one and we don't have Brady Bunch living rooms.

But I do understand Chavez position as he uses a butler and he can't extract that volume of water.

We use the Butlers to clean carpet. We use the Prochem's to extract water and we don't fool with deep water unless its a business where we can get paid for the use of submersible or trash pump. bitch!
