I was talking to another member last night re: pumps and thought I would repost so others may use the info if it helps new roof cleaners to understand chemical delivery pumps better.
Air Diaphragm = A/D SHC=Sodium Hypochlorite
Remember that the 1/2" Air Diaphragm Pump is going to give you more options and flow and the 1/4" A/D is a cheap solution for use mainly in transferring materials from your SHC BULK storage container to your 55 gal. drum. Then if you do eventually decide to run a 55 gal. and one of your 300 gal tanks you should be able to carry enough 12% chlorine in your 55 gal. drum to do 3 average size roofs and just mix and dispense out of your 300 gal. tank.
The buzzwords in Pump materials are Kynar, Teflon or Poly.
Do not use A/D pumps from ANY manufacturer with EDPM, Santoprene, BUNA or other RUBBER based diaphragms as they will rot and QUICKLY degrade with Sodium Hypochlorite use. These diaphragm materials are made for petro chemical fluid transfer.
Kynar, Teflon or Poly are what you want and in that order in terms of longevity when used in pump materials in conjunction with Sodium Hypochlorite, TSP, Alcohol.
I hope this helps to clarify and help dial in your set up.
The Delavans or the FATBOY are also proven pumps and will definetily work also. Just decide on what you can afford and remember , NO ROOF CLEANING PUMP IS FOREVER.
When possible and affordable it is advisable to have BOTH types of pumps on hand so that you are ALWAYS ready to go to the next roof cleaning job ! :)
Have a GREAT DAY!

This is my first post, I have cleaned many tile roofs w/ a pwer but never a shingle roof, that just seamed like common sense to me. I decided after reading and searching here for a few months to start doing it the right way.I have found almost everything I wanted to know, until I read about this versa matic 3/8 kynar pump. I was going to go with two 5850's or two fat boys one for use and one for back up, w/batteries 5/8'' kuri tec on a titan reel. To start w/ the 1/2'' aodd would have cost around $ 1,500.00 for the compressor and two pumps (gotta have one for back up). The versa matic 3/8 kynar pump is very close to the fat boy in specs gpm, psi, and only needs 5 cfpm compessor wich I already have. I will need a small generator 4-$500 but that could be used for other things also. So,wich set up would be better? If 3/8 versa matic, is 5/8 hose still ok? and is the gpm adjusted by air flow?
Thank you, for any response and the time and effort you all put into this forum. Hopefully I will soon be able to contribute as well.
Thank you for responding. The first thing I read on this forum was read, read, read, and I have, almost to the point of addiction at times. Sometimes for 4-5 hrs at a time. I have read many of youre post and agree their should be a fee for this knowledge, and I will soon be donating to the forum. I would also like to know if anything happened w/ the training book you mentioned in one of youre post and any if you or anyone on the forum does hands on training? I have read about the kv-038 and know it is adjustable 0-9 gpm, but that pump requires more cfpm than the versa matic (6.8 gpm,5 cfpm) I also dont know if all air pumps are adjustable through air flow. I guess my question is do I :
1. Start w/ the 5850, 5/8 hose, titan reel & upgrade to the all-flo    3/8'' or 1/2'' after I get a larger compressor. And have the 12v    for back up                                  or                                                                    2. Start w/ the (2)3/8'' versa matic, the compressor I have w/ a    generator, 5/8'' hose & reel.
One of my concerns just starting is flow (gpm) thats why I go with the 5850 over the fat boy & wondering if the adjustment on the air pumps is done though air flow or an adjustment on the pump? Should this be a consern or would I be able to adjust the flow of the fat boy w/ the 3/4'' valve @ the wand?

Valve and wand will do your adjustment as well as air flow. Go with the All flo air diaphragm pump, you won't regret it. Just use 2 air moisture traps before the pump in the air line to protect it.
just to be sure the adjustment can be made at the valve & wand on the 12v systems w/ no impact on the pumps?
I did'nt want to start with the all-flo because of all the added expense, i have a compessor that will run the versa-matic already. My options are pretty much #1 & #2 in the previous post. although i could up grade the 5850's to fat boys, if i went with option #1. The versa-matic 3/8 kynar w/ teflon is almost half the cost of the all-flo. Is there that big of a difference other than flow rate 6.8/9gpm?Â
My friend Dave likes All Flow, and I have not used the Versa Matic. It looks ok, on Paper ?? Please let us know YOUR experiences with it, IF you decide to go with it ?
The difference will be that the All flo does not stall and the Versa matic will. It only means you will have to disconnect the air and reconnect to un-stall it occasionally. I have both these pumps and that seems to be the biggest issue, not a big deal as you can save the Versa matic as a backup (which is good to have) if you upgrade to an all flo.
The stalling happens when you dead-head the pump (caused by putting an equal amount of air pressure and water pressure against the diagram). This is how the pump can sit idle when you close the wand valve for an unlimited amount of time with no by-pass. But this can cause the pump to stall and apparently does with most pumps. My All flo has never stalled a single time as it has an offset in the diaphragm. 60+ roofs and running no problems, no rinsing, totally fine. The versa matic does stall and as I said, no big deal, just have your ground man disconnect and reconnect the air while you keep the gun trigger open and it will fix it every time. I believe the Yamadahs that Chris uses have a reset button on the pump for this issue, making them better as well.
Thank you for youre response, it has been a helpful. I think I will go with the 5850's and get the feel for the flow & then upgrade to the all-flo & keep the 12v system for back up.
Thanks, Robert

      I like my FatBoy. I have 200' hose @5/8". Some have 300' @ 1/2"
I have 200' of 3/4 on my fatboy I just set up. Also have 200' of 5/8 ready to change to. Don't know which is going to work best, but I'm sure I'll find out.
Has any one tried the 1/2 warren rupp sandpiper pumps ? i got one today from my chemical supply guy they look awesome. this is what they look like. http://cgi.ebay.com/ws/eBay ISAPI.dll?ViewItem&Item=26049 7338913&Category=46547&_trkparms =algo%3DLVI%26its%3DI%26otn%3D2

I started out with the 5850 pump, then the fatboy 7800 series. I have been running an air pump, the yamada poly pump, 200 ft of chemical red hose, both roof washing hose and pressure washing hose on two titans stacked. Both of my 150 gl tanks are pulled from the top, running 3/4 pvc piping up to 3 way poly ball valve. Then 3/4 hose to my yamada air pump, from pump to hose reels 3/4 hose. Also my 200 ft of hose is 3/4 to a 3/4 ball valve. My next purchase will be a all flo 1/2 pump for a back up until the yamada go's out.Â
I rinse after every use, unless I am some where like court house estates and the houses are within a few minutes of one another than I just move to the next house. Make sure you rinse your air pump and it should last a while. I am going on over a year with my current pump, but like Chris would say pumps do not last for ever.
I am a rookie over here so don't bash me if this is a stupid question, but where are you guys using air? I tried to dig around the site and find exactly how your setups are using your air compressors but I am a bit confused.
