I have had some spare time while I am recuperating from surgery. I bought a few of these

that I am tinkering around with.

I also bought a yamada ndp 15 fps that I know nothing about. Anyone know how how big of an air compressor I need to run it. Do I need an unloader on it. Trying to make a 10+ gpm rig to rinse with for doing apartments. Thanks
 
Those trash pumps sure can move a lot of water fast. That is what was on the water trailer that I used in December 07' for the Airport Radar Tower Cleaning job.

I was looking for something smaller so I could let it run for longer periods or slow it down so you don't have to watch it so much.

We used the Trash pump to transfer water from the water trailer (500gallons) to the 275 gallon tote on the ground and from there I used the 5gpm AC Delavan to transfer to the pressure washing trailer.

Reason for all this is there was no water on-site so we had to get water from the control tower and bring it to the site continuously. It did work out good but wish I had a gas powered pump back then.

I have the same pump, polyp/Teflon, both have exceptional rating for use with hypo. Not as good as Kynar, but good enough. I still always rinse out after each use. An unloader is not needed, when the valve is off the pump is off. For air supply I use: http://www.tractorsupply.com/webapp...10551_10001_35686_-1______?rFlag=true&cFlag=1

We feel the YamadaNDP 15 series is the best roof cleaning pump.
The Kynar version is best for lazy folks like us too stubborn to rinse their pumps out.
But the Poly lasted ME a year on when I rinsed it out.
You need an air compressor that will deliver 9 to 12 cfm at 90 psi, the more the better.
There are other companies making air diaphragm pumps, and they are good too.
When it comes to the air diaphragm pumps, it is like Ford, Chevy, and Dodge, what is "best" is a matter of opinion.
Right now, I have a 2007 Ford F 150 as my personal vehicle.
I am a "Ford Man"
But I am seriously eyeballing the Dodge Pick Up, because of the Hemi !
Hey, 390 HP AND 20 MPG :p
I have had good luck with the Rigid compressors from Home Depot with my air pumps, and recommend them.
Here are some pics showing my Yamada Kynar Pump, and the Rigid Compressor.
I use Synthetic Compressor Oil too, and Gates Belts I get from NAPA.
I do NOT buy "Junk Belts" for our Compressors.
The Yamada has a button you push IF the pump stalls, a VERY useful feature IMHO.
Keeps you from having to purge your line of trapped air if the pump stalls !!
The Yamada Pumps are THE most reliable roof cleaning pumps I have ever used.
I recommend them highly

Thanks Chris, it looks like you just drop a feed hose in the top of whatever tank you are using. No problem with priming? It looks like I won't need an unloader. What is the pump doing when I am not flowing water? Thanks.

It's just sitting there, holding a small amount of liquid ,...just waiting to get back into action. Now and then it will go on strike.

The air compressor acts as an unloader, and when it senses pressure, cuts out.
Keep the pump as close to the tanks as possible, and you will never have a problem with priming.
One pump valve has superior suction lift then the other kind, but both have plenty, as long as the feed line is kept short.
The pump is primed and pressurized, and ready to spray when it senses demand.
The compressor will cut down to idle, and the pump will run on the air in the dual 8 gallon air tanks.
When THAT air is depleted, the compressor kicks in.
It WOULD be nice to have a seperate 100 gallon air tank to make life a bit easier on the compressor.
But this is a proven roof cleaning system, the way it is.
BTW, a BIGGER air compressor {more CFM}, turns this 15 GPM pump into a super pump.
I used this pump with a 18.7 compressor for awhile, and it was HARD to control run off on residential roofs.
For the VERY first time, I found a pump that had too much flow, LOL
 
Chris, thanks so much for the info. I don't care about roofs, ya'll can have them. I want a hi flow, low pressure pump for soaping and rinsing apartments. I usually work off of hydrants so water supply is not a problem. Thanks again for the info. Sounds simple enough. OK one more question. What do you use for a nozzle. I was thinking about a 0070, but I guess a garden hose nozzle would work. I was planning on using 3/4 hose unless you have a better thought.
 
We have used the Yamada and other variations with an 9,11,16 and I'm very close to purchasing a 32 cfm machine we tested recently.

Like stated earlier the flow is great and pressure is perfect for roof cleaning.

As for exterior washing or flatwork rinsing it just doesn't have enough PSI.
Very bad in a small amount of wind.

Comparing exterior washing with using roller pumps, tree spraying pump and the air pump the tree pump was the obvious choice.

I have used a 17gpm up to 700 psi tree pump rinse flatwork like you can't imagine. This pump can shoot at full throttle (17@700) 6 stories without a tip, that's straight out of the ball valve. And can be brought down to 50psi----The wetted parts are not as durable as the parts in an air system.

So, we clean more roofs than any other surface, that is why we use an air pump and 12v.
