I'll bring my air pump. :thumbup2: And my Delevan...LOL
Keep in mind that Shoot farther and all that stuff is not what a true demo is about. I would like to get two homes similar next door to each other.
Let the guys that are familiar with there own stuff have a home cleaning contest.
Lets measure the chems, quality and the whole deal.
Energy used is a factor as well.
I'm curious, i also know someone with a pressure tank system. I want to see if he will be willing to show.

The All-Flo Air diaphragm pump has a FIVE YEAR WARRANTY. The KE038-B3 can handle sodium hypochlorite, TSP, Caustic Soda, Sulfuric Acid, Hydroflouric Acid and mmany others. Why replace a $115 or $215 Delavan every 3-9 months when you have a pump that is design engineered by All-Flo for the industry? When I perform the math, it looks clear to me that the pump pays for itself in savings on time batteries, fuses, and frustration.
One of the best features of using an air diaghragm system is that they allow you to control how much chemical you apply. As I stated above, you can use a 2.0 nozzle. William, a 2.0 nozzle is the nozzle size that is often found on a surface cleaner hooked to a 4 gpm pressure washer. Using an air diaphragm system will allow you to completely CONTROL the amount of chems that you apply.
Pressure gauges are critical in this industry. We have found that very few individuals can 'feel' the pressure and know what it is. For example, failing to use a pressure gauge when setting your unloader can cause you to blow the head off your pump! Seems dangerous to me and rather wasteful to fail to use a pressure gauge.

If Ron buys me a ticket I might come
. My Fatboy's are over a year old and still kicking. I can talk you thru how to set an unloader without a pressure gauge. They really have no usefullness. Using an a gauge to set an unloader does not allow the full potential of the pump. It may seem wasteful and a way to blow the head off of the pump, but with experience and training it is not an issue. My pumps are set for the max flow of water possible, pressure should be a secondary concern, if any. I have a lot of certifications from every pump from waterous to hale. If you ever need help or a talk thru, call me.

William, Happy Easter!!!
William, spend a buck and buy your own ticket!!!
Have you run any of your wild ideas past the pump manufacturer's? You set the unloader 200lbs above the working pressure of your pump. Please do not give advice on technical issues. You may need to carry liablity insurance with that sort of advice.

William, rpm is the determining factor of pump volume. Horse power is the determining factor of how many gallons make it through the unloader with proper nozzle sizing and proper pressure adjustment and the proper unloader.
I could get into 'lock-up', 'flow activated', 'pressure activated' and 'flow sensitive' unloaders and hose id, length, and all those fittings installed along the way, (don't forget the downstream injectors, 90 deg fittings, trigger gun options, hp filters), is it tank fed or hose bibb pressure, is it direct drive or belt drive as you know all are contibuting factors to pressure and volume at the nozzle, but I think that it is way over your head.

All-Flo is $400
Mini Intergral Filter Regulator with a pressure gauge that you may pruchase when you buy your compressor and sometimes a dessicant filter
A 1/4" hex nipple in brass for your Mini Filter/ Regulator
You can buy your 11 cfm compressor anywhere that you prefer to shop.
5/8" chemical hose to the length that you prefer (average is 200')
Length of ag hose to supply your pump with a crimped end and a pvc slotted filter attached to the opposite end to drop in your tank. (We show and teach you how to build your own)
Ball valve or poly gun assembly for the chemical application (We also show and teach you how to make your own to save you money)
Nozzles
Some 568-110 90 durometer viton o-rings (1/4" viton o-rings)
There are many variable depending on a set-up.
Great question, Scott!

I have used every 12 volt out there and most of the gas powered chem pumps, they all have their uses some are better than others. High flow pumps are great for certain applications but for roofs you get to much runoff.[IMO]I can shoot a roof just as fast with 5gpm as someone else can with 10 gpm and get alot less runoff. less chem usage less chance of plant damage same time on job. I personally like to have more than 90 psi available to me so I would have to pick a gas powered diaphram pump. but I always carry a backup 12 volt.
Ok so assume someone already has the hose, gun, reel and nozzles. What is the total cost for everything else including the compressor if someone were to go through PWP?

Scott,
I don't normally just give the customer an out of the box system. I ask a lot of questions and I like to get to know what the customer's experience is prior to making the purchase.
Most guys that have purchased the All-Flo's or Delavan's from us, have been on the phone with me and sometimes my Father for a bit of time.
Currently, PWP is not a distributor of air compressors. We are in the business of offering the best products for the best pricing. We usually guide customer's to the best deals on the compressors.
Without the compressor, you will receive the All-Flo pump with a 5 year warranty for $400, the 1/4" hex nipple for under a dollar and the filter/reg and pressure gauge for around $40, and a length of parker air hose with crimped brass fittings for about $5.
Rough math........$446.
OUTSTANDING return on investment.

OK I found a 10.5 cfm doing a quick search for $459.00. That totals $905.00 give or take. If you were to replace your delevan once a year (unlikely if taken care of) it would take you roughly 4.2 years to break even compared to buying the allpro system. Thats if you don't include the wasted chemicals, which there will be for most people with a high flow pump.
Lori it just doesnt make sense. Im not saying dont buy an AllPro setup, but dont go into it thinking you will save money. You wont, not for 4-5 years.
MEDIOCRE ROI.

Scott, this is the part your not getting. I use a fine misting fan spray pattern with the air set up and go through WAAAaaaaaaaay less chems than I ever did with any of the 12volt systems I ever used. I used to watch my tanks drain very quickly which in turn was costing me a fortune. The $$ I'm saving in 1 week on chems (on a busy week) just about pays for the pump alone.
If you have had and are still having great luck with your 12 volt then keep using it. I NEVER had luck with them and went through tons of $$ replacing them. Since switching over I have had ZERO problems and the first couple roof Cleanings we did paid for the pump AND the compressor.
You set yours up right next to mine and we will both cover the same SQ footage. I will guarrantee you that I will still have way more chemical left than you when we are done.

Scott, I respectfully disagree.
(Good find on the compressor)
You are NOT WASTING CHEMICALS. In fact, you use a lot less chemical than you do with a 12 volt set-up. You are not using a big tip such as a 50. The average tips are 15, 20 25 or 30. Smaller tip equals less chemical. Use a surfactant such as Dawn or Ammonyx and even less chemical will be used.
How often do you have to go out at the end of the day and charge your battery? How often do you upgrade wiring and the related components? How long does your battery last?
With the air diaphragm system, you add gas to the gas powered air compressor.
Just becuase it is rated to 9 gpm, doesn't mean that the user is fully utilizing the 9 gpm.
My math clearly PROVES that you save in chemicals and time. Most people in well run businesses understand that time is money. Ask Ron.
Air diaphragm users do not have to babysit their pumps and listen for the cycling.
No matter if you target residential or commercial work, I am assuming that users are working to put food on the table or save for roundtable events(!) and this is not a hobby. Downtime should be considered critical. We answer calls in the middle of the night with customers that have equipment failures. UPS doesn't ship cheap for same day deliveries. Shops are not open in the middle of the night.
We have accounts that lose $15,000 an hour for downtime. These accounts rely on these air diaphragm pumps.

Larry,
Thank you for the clarification. I tried to explain it a couple ways and you hit the nail on the head!

At least you are showing your true colors and complete ingnorance of pumps. Maybe people will see you now as I heard you in you phone call to me. What are you talking about with comments like 200lbs above the working pressure of the pump. Don't give techinical advice. I have a lot more knowledge of pumps and machines that is evidenced ny your posts. And I didn't have to get people to send me pumps from another manufacturer and reverse engineer it. How many minutes will pass by before the crying starts and the post is deleted. I understand you have to make a dollar. Don't do it by crapping on your customers and claiming that pump maufacturers intentionaly put tef tape on products to generate income or some of your other "weird" ideas. Suckering these new guys into air pumps and what not to make a quick buck is not the way to create a long term customer. I know you are new to this and there is a learning curve, but come on. Are you always this condescending? I know how a pump flows water thru the hose. If you believe that a pressure gauge is the correct way to set the unloader, then you are performing a disservice thru your lack of knowledge to your customers. Carry on and I hope you make a ton of money, there is a sucker born every minute.

William, I NEVER have your posts removed. I have requested them to be replaced. Ask the mods.
Show me the post in which I claimed the teflon tape controversy.
Poor William. Are you intimidated by a girl???!!!!

Lori,
We have not charged our battery in over a year and have never had to buy a new battery. How is this you ask? We wired our battery into the trailer harness! I figured that out and dont even have a degree in rocket science!
We pull up to a job, flip a switch and get to work. At the end of the day, we back our trailer/truck into our shop, shut the doors, and head home. No charging, no upgrading, no babysitting, no downtime.
If you have roof cleaning clients who lose $15k per hour, please let me know who they are, because I could use some advice. If you are talking about larger companies doing work other than roofs, such as fleetwashing, tank cleaning/blasting etc, then yes, a larger pump is great.
As for the nozzles, we use a mix of 30's and 40's depending on the job, and can reduce down further if needed (which we never do).
If someone thinks that one day they will need a 9gpm pump, then by all means, buy the biggest and best you can.
For a company like mine, which does 2-4 roofs a day, it is overkill. Refer back to my post to Ron about buying a ferrari and governing it down to perform like a prius. What a waste of money.
Now Larry,
It is impossible for me to combat your post unless we actually did jobs side by side. However, you say we can cover the same square footage and you would have more chemical, that is also a statement that can not me proven unless tested...With that being said, when I have worked with others using other pumps, I was SHOCKED at how much chemical they used. I would fire my guys if they blew through that much on a regular basis.
This whole thread started because of the BOGUS claim that 1/2" hose is the cause of the pump issues. Nobody can seem to explain how we have been using a 1/2" hose for over a year and not had 1 pump burn up. hmmmm....
That claim should stop until it is proven, or else you should be offcially infracted by the mods.
