Hi and Welcome Steve. I use the All Flo KV-038 and find it far superior to my 1/2 inch poly pump. It is an honor to have the engineer behind this excellent pump on the board.  With its all Kynar construction and 3/8 inlet I get 7gpm out of 150ft open ended 5/8 hose with 9cfm@90psi!!!  This pump has been a monster and seems to be the one I will continue to use into the future.  I hope that you find your time here at the RCIA to be well appreciated by the members of this board, as well as a chance for others here to realize the power and longevity of this compact pump.


Kynar pumps can potentially last for years without even rinsing!!!
(though I still do rinse).

Again Welcome Steve, I look forward to your responses on the board.

Welcome Steve !!!
I found the Yamada AODD pumps out of sheer desperation.'
NOTHING else lasted long for roof cleaning.
Started out with Poly Yamadas with Santoprene diapraghms.
Worked ok, as long as rinsed out promptly.
If not rinsed out, maybe 6 months life before they leaked all over.
Went to Kynar Yamada NDP 15 FVT pumps wioth Teflon Diapraghms.
I own 5 of these pumps for my 2 roof cleaning trucks.

I have rebuilt them 3 times, they are still going.
i HAVE never TRIED ANY OTHER aodd PUMPS Steve.
Oops, caps locked ....


The reason I have been reluctant to go away from Yamada is they have a push button on the air motor, and NO other pump does.
When the pump stalls, just push the button!

I have been told by several of my friends that All Flo Pumps are superior to Yamada ?
If they are, I want our roof cleaners to have the BEST.

I have looked at several AODD pumps, ALL claim they are the best.

Are your air motors grease free Teflon ?

WHAT makes an All Flow Pump better then it;s competitors ?

I am interested in that grease free question as well ??

Chris mine dosn't stall, not once yet....though I definitly clean far less roofs than you master jedi wink

My 1/2" versamatic stalled every time it deadheaded and had to be disconnected then reconnected.  I wonder if you guys can tell me does the stall only happen when you deadhead (close the valve and create deadhead pressure) or does it happen other times as well??

Anyway so far no stalls with my All-flo, can you tell me why it isn't stalling steve, as well as if and why it would??

I run 9cfm @ 90psi through 3/8 air line and a moisture trap.....getting 6-7gpm out of 150+ft, 5/8 hose with no restrictor.  KV038

Yeah, I wanna know about what makes an All Flow such a good pump ?
And WHY AODD pumps sometimes stall ?
My Yamada's  stall sometimes when deadheaded with smaller compressors.

Hello Chris:

You discovered something about how bleach and polypropylene by the school of experience.

Polypropylene will be attacked by bleach. Every chemical compatibility book in the air operated diaphragm (AOD) business will list Bleach as a non recommended rated material for polypropylene.

You were wise to wash out the pumps with water after using them. This gave you the 6 months of life.

As for Yamada and their famous reset button.

They need a reset button on there pumps because they use a balance air valve in there pump design. It would cost them more to make an unbalanced air valve.

A balanced air valve can get stuck in the middle. By the way the air valve is the devise on a diaphragm pump that tells the air to go to the left or right side of the pump.

Yamada is the only AOD manufacture that uses a balanced design, therefore they need a button the the air valve to fix the air valve when it gets stuck.

We at All-Flo do not have a button because our valve cannot get stuck unless something physically would get into the air valve and physically jam it. This is unlikely because most people put some sort of a filter regulator with a clear float bowl on the compressor and air line to keep the air clean and moisture free.

Steve

WHAT makes an AODD Pump stall sometimes when the flow is closed, then restarted ?
If your pumps stall, what does one do ?

Bill:

You are correct in that the Versa-Matic pumps normally do not stall. However they do recommend that you use an oiler. There pumps do not require you to run an oiler but if you want to prevent the dead heading problem and good good service life out of the pumps I would recommned you put one in. An oiler is a device outside ot the pump, that will mist a tiny bit of oil in the air line. Oil lube was popular years ago but is becoming less popular today for many reasons. (Old diaphragm pump designs always used an oiler) Most workers do not want to breath oil misty air. I do not. Plus you have to remember to fill the oiler up every week. All-Flo uses a design using dissimilar plastics to makes our air valves self lubricating. Oil misters actually can cause a small [roblem over time if you use one with our pumps. All-All-Flo pumps need is clean air.

So it is balance and lubrication that causes stalling?? Interesting. I just took the KV-038 apart for a clean out and will post the pics and instructions soon. Do you have a torque spec for me, for the bolts on the KV-038.

Here is my thread on assembly/disassembly if you want to see the vers-matic torn down. It is also were I will be posting the KV-038 teardown.

Non- of this would have been possible for me without the Certified instructors on this forum.  Thanks for making me apart of your team and providing me a chance to learn as well as share this information.

Don't know yet. I looked at the flights and what not and can afford it as long as my employees are set to work while I'm gone. I have to coordinate with the other guys first and see what best represents the RCIA. I always thought round tables were a way for distributers to sell us more crap, so I used to avoid them. I have seen after attending the recent one online and hearing from others that there is some real benefit to being at one.

I thoroughly understand trying to get good work out of your employees when you are not there to supervise the situation.  True vendors are there but so is a wealth of info and you get to meet the people face to face that you write to online all the time.  I hope you can make it.
