Great find Russ!

That is a very good price.

If you had problems with it, I wonder if they stock parts for the compressor?

What advantage does the air driven pump have over a gas? Is the air driven a non metal diaphram pump? I have a AR-30 diaphram right now, but I dont think it would last long with this roofing solution. So the dual tank compressor runs the pump, correct?

Mike,

Thank you for that. Thats what I thought you might say. I looked online, but had a bit of trouble finding a price for the pump. Am I assuming that you guys use 5/8 ID hose with the smaller 15, while the 25 should use 3/4 hose? And does the larger 49gallon pump work ok with the dual air tanks? I thought I read someone was thinking about a larger electric compressor maybe to combat with the compressor playing catchup?

Yes, 5/8" for the 15gpm is what Chris and Dave use.

Dave is the only one I've seen that uses those monster pumps bigger than 15gpm. 
He must be on crack, HAHA!!  jk.

49gpm is just a ridiculous amount of flow, and only needed for large commercial jobs.

It might be too much if the complex did not have a drainage system.

The Yamada 15gpm is plenty.

I also agree with all the guys about the compressor Russ posted at the top. 

That is the best deal I've seen for a 12 CFM compressor.  Perfect for the 1/2" 15gpm air pump.

For reference,

I use 1/2" , 5/8" and 3/4" hose, SOME of my reels have 1/2" Kuri Tec Agricultural type 600psi burst strength.

I also have a 30" Summit Reel with a 1" Manifold and it has 3/4" Green AG hose which was costly.

I also have a large 28" Titan Aluminum and SS Reel with 5/8" Kuri Tec.

I mention this so you all realize I have a variety of hose dia. and types.

Everyone ALSO needs to know that under normal job circumstances, the YAMADA NDP-25 in KYNAR which we own, can deliver a max. of 49GPM and is 1" in/out, but, for MOST, average roof cleaning situations is way OVERKILL.

Yes, like the wife says, bigger is better,LOL, but in this case, not always so.

I have it SPLIT into TWO 3/4" hoses and with 200' of hose on each reel its liquid delivery is, to say the least, MASSIVE.

I don't have enough buckets and can't seem to look at the timer while filling, in time before all the buckets I put out are FULL. It's maybe not not quite as fast as that sounds but it is amazing how much liquid this pump can actually flow, and you still have to take into account FRICTION LOSS yet this pump still is like a mini FIRE HOSE and is hard to hold onto at full pressure and flow.

Mind you that is with a 3/4" hose open flow and no restrictions. When I put nozzles on the end of the hoses and run the pump, with the compressor I have now, it does not have anough CFM to run this monster pump continuously without stalling which is why I recommend anyone seroiusly think of doing big jobs or multi hose reel rigs with a big pump go to a 30 or 60 gallon tank and a 13 hp honda motor and at least a twin cylinder but preferably a V4 air compressor pump to keep up with flow and demand and air consumption.

The air compressor offered by Water Cannon is a good deal price wise but it is a CHINESE built Asian made compressor. If it fails it may be very hard to get parts for and to have serviced. The air compressors parts may not stand constant cycling of the compressor as the tank that is storing air is only 9 gallons.

It is my experience that a tank with 30 gallons will be much more effective. You could buy this Portable compressor from Water Cannon and get an Add-On Storage tank at auction or make your own from a broken compressor by taking off the broken motor, plugging the outlets except for one in and one out. This may work well.

Another thing to consider, air compressors are like cars and and there are many choices and models and quality varies greatly.

A few things to keep in mind is that Cast iron or FORGED, HARDENED RODS and Wristpins last much longer and are replaceable, as compared to, aluminum or Stamped, which wear out quickly.

And Reeds in the Air Handling pump do not last and are not rebuildable most times in the "throw Away" style compressors that are lower priced.

However, Discs in the Air Handling Pump are the Commercial and preferred way to get long pump life out of a quality built air compressor.

Also, VERY IMPORTANT is RPM (revolutions per minute), this little abbreviation can be the DEATH RATLE to a compressor. The rule of thumb is less R P M = Longer lasting Compressor and Motors. Get the LOWEST RPM compressor you can AFFORD.

Also from my research, WARRANTY is usually a PRO-RATA type on less quality compressors where as if you spend a little more you can have a 5 year bumper to bumper warranty from a company like EATON COMPRESSOR that stands behind every compressor they buildand they build them in the USA, in Ohio, and try to use mostly ONLY AMERICAN MADE parts, and have been in business, I believe, for 31 years.

Yes, This Yamada NDP-25 is way more pump than most of you will ever need, its just that I wanted to try to build the ULTIMATE ROOF CLEANING RIG and that was and still is what this Yamada NDP-25 Kynar pump will be used for. I will show you the pics when I get this MEGA roof Cleaning Rig finalized and completely "DIALED-IN"...Until then...

I have been testing this just so I could have it online and READY when the big commercial roofs come along, here and there. And they do from time to time.

For all practical purposes, the Yamada NDP-15 in 1/2" flow IN/OUT in Poly or KYNAR (PVDF) and the (Ingersol-Rand) ARO 1/2" Kynar that I and Chris T. Of Apple Roof Cleaning have are the best of the best in chemical delivery system solutions for minimizing downtime and maximizing ROI.

These air diaphragm pumps are what most roof cleaners will one day eventually want to move into purchasing but for many the cost to play in the park with these pumps and the additional compressor cost keep most out of this buying arena.

Th bottom line is that once you try using a air diaphragm pump system and deliver chemical to the roof using this method over the other available methods, you will most likely be sold on the concept and will upgrade all other rigs you own to this chemical delivery method.

The REASON....They work, they are a lot more simple to operate and they don't breakdown most times, and if you go with the ARO model with the uneven crankset for the motor, it will almmost NEVER even stall, with a decent compressor and a 15 or 20,30, 60 gallon buffer air storage tank.

The key is always have a backup pump in ready and in wait for when the PRIMARY pump fails, and believe me, it will FAIL one day, when you least expect it.
But with a backup, just unbolt the base of the broken pump and sned it out for service or rebuild it yourself and put on the SPARE pump, tighten the bolts and liquid fittings and you are off and spraying again.

Sure your out a few bucks on the front end but on the back end you will be cleaning more roofs and spending less time in the shop.

You do the math!

All the Best to you all, Dave- Roof Clean USA

Great post thank you! Am I to understand by your post that even the 15 with a small gas 9 gal compressor you are getting some air flow problems?

WOW 
Excellent post Dave, I think im going to print that all out, alot of knowledge to take in for a newbie...

Thanks again my friend,

Hey Dave or Chris, what do you think of this air compressor. It looks pretty good.

That MIGHT be MY next air compressor !!
The Rigid we have been using is no longer sold  at Home Depot.
I HAD one of those Chinese Compressors like the water cannon one in this thread.
Gave it to my Cousin, couldn't keep it running long!
The Chinese Motor no match for a Honda.
Had to pull it several times to get it started, put too much  strain on recoil mechanism.
It was constantly breaking!
It DID have a LOT of air, when it worked.
The Norther Tool Compressor you found Mike has a 20 gallon Tank!
THIS is a GOOD thing.
I think this will be MY next Compressor ?
Good Find man !!

 

Would a compressor like pictured above, but a honda, rigid or something with a 9 gal be enough for the ARO series Ingersol-Rand Air Diaphragms 15gpm? What is the CFM I should be looking for? I dont want to by chinese, but would like to know what combination air compressor and pump works best. I would mostly be doing res work for now. I have some Delevans but I use them for something else. I could use a compressor anyway so this would be just another reason to buy one.
