Russ, is the Pump Head of the Fat Boy Roof Cleaning pump the same as the old Delavan ?
Is it JUST the motor that was changed ?
My air Pumps, with larger compressors are almost too much to control.
I have a 19.7 CFM Compressor.
My roof cleaningpump only callls for between 9 to 12 CFM at 90 PSI.
The exactsame pump, with alarger compressor, becomes a whole new animal.

Chris the head is the same, it does produce more volume but it actuall just gets the specs that the 5800 was supposed to get but does not I did a test yesterday and it gets about 5.5 to 6 gal a min at 60 psi with a 2530 tip and 250 feet of 5/8 hose.

So I am not too impressedb but it is better because the pump does not have to be over worked to get the volume that I wanted out od the old smaller pump so I guess we will try to get back to roof cleaning in Montgomery Alabama with this new one and see how it does

I figured they would use the OLD, proven roof cleaningpump head.
Pressure is all about the motor.
They went to a bigger motor, a wise thing IMHO.
Mel from Vero Under Pressure went to the big Kohler motor on his pressure washer.
The big Kohler makes tons of torque at lower RPM's then the Honda.
Mel told me it was like getting a new pump!
Cooling Fins can be helpful on 12 volt motors.
Wonder if Delavan will make them an option on their roof cleaning pumps.
I had them back in the day on my Dual Shurflo's.

Is that something that can be added with some Alabammer (or Missipi) Engineering?

Hey Guys,

I'm Ryan.....Newbie to RCIA here. lol

Has anyone had a chance to use the new "Bobcat" that Bob put out?

I really need to get away from drawing from batteries and this one looks like it would be real solid being that it is the Delavan 5800 head.

Wonder if the 7800 head could be fitted with it instead???
That would be cool!

Also, does anyone use the Zeta by Udor.
I planned to get a 40P after the first of the year but it would be interesting to hear reviews on it.

Thanks

It is the same head just a bigger motor and the bobcat only uses the head from the Delavan so It would be the same either way

Duh...I guess you did post that already.
Sorry bout that.

So I wonder if it is a torque thing or a RPM thing. Probably both to some extent I would imagine. Wonder if it could be tweaked???

I really do like the "Bobcat" concept.
*Uses very little gas
*Runs over 2 hrs on a tank
*Delavan head
*Good volume

If its possible to get the psi up a bit, this would be a really cost effective system.

Welcome to RCIA Ryan!
Chris from Apple Roof Cleaning in Tampa here.
The Udor and John Blue Pumps, and the Comet Pumps, and the Hypro roof cleaning pumps are all made in Northern Italy.
They all "work" for roof cleaning, but fail too often for our use.
I used the Udor Pumps, had 3 of them.
Still have one in pieces in my shed.
The PROBLEM with them for roof cleaning use is this.
They have stainless steel valves and springs.'
Stainless sucks for roof cleaning use, only having a "C" rating for SHC use.
And THIN stainless steel, as used in valve springs REALLY sucks.
The springs will break, and the pumps are a nightmare to rebuild.
Then, the Poly Manifolds leak.
My advice ?
STAY AWAY

The Bobcats and Fat Boy's look lnteresting.
If it were me, I would take a Bobcat, and simply replace the heads at low cost when they fail.
And they WILL Fail, bet on it.
No "roof cleaning pump" is forever my Son.
They are ALL "living on borrowed time".
Some just die sooner then others.

Always remember that your roof cleaning pump, whatever it is, is living on borrowed time.
Thus, you must make life easy on it, just as you open doors for littleold ladies.
You do this by using the BIGGEST diameter, and shortest length of Hose you can for roof cleaning use.
Welcome here Ryan, this roof cleaning forum is moving up on Google quickly!
I would take some before and after roof cleaning pictures, and post them in the picture section of this forum if I were you.
Use the tags so they show up in whatever Pinellas County Roof Cleaning Search you do.
This way, potential roof cleaning customerson your side of Tampa Bay may see your work ?
If I can ever help you, just ask ?
Chris

Thanks Chris,

Thats disappointing about the Zeta. I had high hopes for that one.
Yeah, I probably will try out the Bobcat but I still want to find a pump for a 3/4 shaft gas motor that can do a higher volume and PSI. Mabe I'll just have to go roller...

Thanks for the heads up!

Rollers dont last long either, but they are cheap, and easily replaced.
I once used a 4 roller hypro for roof cleaning, replaced it every month.
Hey, I bought a case of 12 roller pumps for 65.00 each!
If I cleaned 45 roofs with one pump, I did not shed a tear.
Cost of doing roof cleaningbusiness ya know ?

12V Delavan FATBOY 7gpm pump
Permalink  
 


The FATBOY 7gpm pump needs LARGE nozzles and hose
#30 nozzles and 5/8" hose are too small, and are meant for the old 5gpm pump.

Using the #30 nozzle causes the 7gpm pump to max out at 25amps draw and will choke it, running at half speed. These nozzles will quickly kill your pump from excess amperage draw and overheating.

#40 works better but it is still maxing the pump out at 25amps, and chokes your flow running at only 2.5gpm.

Use at least #50 nozzles. This is the smallest nozzle you should use for the new FATBOY. Pump will run much smoother and shoot farther than the old 5gpm pump without maxing the pump out.
Pump performs at 80psi 4gpm drawing 21amps.


#60 nozzles also work well to give you more flow and good distance. Pump runs better than the #50 nozzle but does not give you as much pressure/distance (but it is still good).
Pumps performs at 60psi 5gpm drawing 17amps.

Use 3/8" barbs for 40psi 6gpm drawing 13amps.

Use 3/4" hose for the 7gpm FATBOY.

Thanks Mike for the roof cleaning pump information.
Your research confirms that big hose not only sprays better, it makes life easier on any roof cleaning pump.

What kind of trajectory are you guys getting out of the Fatboy with #50 nozzles and 3/4" hose? Can you shoot roofs from the ground like you can with the John Blue DPS-43 and the Udor Zeta pump? 3/4" hose sounds like it would be cumbersome to drag around. That is big hose.

I use 3/4" Kuritec PVC hose. It is surprisingly lightweight. I haven't used the John Blue or the Udor Zeta pumps so I can't compare it to the FATBOY.

The FATBOY is the best pump for the money. At $229 it's half the cost of most gas powered pumps and it's power supply is also much cheaper. A good battery is about $100.

It also rivals the performance of gas powered pumps. I don't have any problems reaching any roof top. I always shoot from a step ladder or ladder because I can see what I'm doing better. The FATBOY can shoot 40 feet high easy.

Thanks for the info Mike. It gives me a lot to think about, since I am about to put together a roof spraying setup. I was leaning towards the John Blue, but now have to consider the Fatboy.

Where do you get 3/4" Kuritec PVC hose at, and how much is it per foot?

Just to make sure I understand things here correctly: Are your posted results with the Delavan with one Delavan or the dual Delavan setup?

Great info guys, Thanks.

Looks like the Fatboy is a good pump. I heard that it is better to run it with 2 batteries because of the amps it pulls but I do not know that much about it yet.

I am still using the old 5gpm Dual Delavans. Together they push 10gpm open flow with no nozzles and 6gpm with #60 nozzles.

I bought two FATBOYs to replace the old pumps, but I haven't installed them yet because my other pumps are not dead.

I hooked up one FATBOY temporarily to see how it performs. It's very impressive.

Power supply depends how good your battery is. I use a cheap $60 battery, but it's good. 770CCA/900CA.

I'll look into getting a better deep cycle marine battery, perhaps an Interstate for the FATBOY when my other pumps die.

If your nozzles are smaller than #50 and your hose is smaller than 3/4" it's going to draw more amps than necessary. So two batteries would help but it will kill your pump faster from drawing so much more amperage.

It helps to upgrade your hose and nozzles, so the pump will run smoother and draw less amps. If your battery is inadequate then yes adding a second battery would help, or just buy a stronger battery to begin with.

Back when we ran Shurflo 12 voltroof cleaning pumps I always used a deep cycle Marine Battery.
I simply charged it every night, and was good to go for roofs the next day.

Thanks for the link Mike. I take it this hose holds up to chlorine ok? The guy on the phone at their HQ was questioning its ability to hold up. I found a distributor in Atlanta that sells it for $.79 a foot for 300 ft rolls.
