Many of you guys switched to air diaphragm from 12v pumps a while ago. Kory, Russ S, Larry and others I think

What is your feedback guys so far?
I have a Ridgid 9GPM/5.5HP that I use to rotate tires on the trucks and emergencies.
I wonder if I should get an air pump or another 12v for back up. I still have this air diaphragm pump that I picked up from an auto shop, but Im not sure if it works at all. I also don't like another piece of equipment like the air compressor, compared to the small 12v pump. So far the 12v pump has been great.

Thanks guys!

I bought the air diaphragm pump with water separator but did not buy the huge air compressor to run it......yet.

I am waiting for the need for it before I spend that kind of money since the roof cleaning business is a lot slower compared to last year.

I would keep doing what you are doing and if/when the 12 volt pumps give out, then you can throw the air compressor onto the rig, do the connections and get the job done with the air compressor and air diaphragm pump.

I would test out the pump as most are not made to handle the SH but rinse it out good when done if you are not going to be using it, just keeping it for a spare.

Most of those air diaphragm pumps need from 9-12 cfm's to operate so most air compressors won't handle that kind of cfm so I would not buy another air compressor unless you put your air diaphragm pump into service full time and even then, unless you have to have an air compressor that big for the shop, I would try to make it with a smaller air compressor unless the duties of the big air compressor can wait unti the rig is back at the shop. Just my opinion.

Good Luck.
 
D,
I switched to the air pump almost 2 years ago and I will never go back to baby sitting another 12 volt pump. The air pump has been used for delivering SH, caustic degreasers, and even oxilac acid. Only recently I had to have some minor work done to it but that was/is expected with the amount of usage that it gets. I still use a 5850 Delevan for transfering chems from tank to tank while we are spraying roofs to make more mix but the end is not restricted by any tips and works great for that purpose and that purpose only.
 
We use a "small" diaphragm pump (3gpm 100psi) for caustic. The pump is warranted for 3 years, but cost $500 and a rebuild is about $300. Very reliable! I've considered 12v, but most of my suppliers swear this is the best for my application. I'm interested in more capacity, but it seems there is a large gap. The next step up is an 11gpm with extreme cfm requirements.
 
I love my Delvan and it pumps like hell thru 200ft no problem. I dont see how you would need more than that for softwash? And I have had this one for years with no problems.
 
CETA is meeting right now to take care of that problem. The pumps you are using are far to efficient an cost too little. Surely there is a safety shroud and mandatory gas masks and other equipment that must be added to increase distributor income and decrease that ridiculous hourly profit the contractors are now taking home. Watch you local papers to monitor their progress. IT"S FOR THE CHILDREN!
 
Sounds like if you have anything that is efficient, they want to put a shroud on it somehow.

Well I done my first roof job today and I bought the twin pump setup that Paul sells at the PowerWash store and I loved it,it was a one story house and did most of it from the ground.

Even the largest air pumps will run with little air. They just will not get all the flow they are capable of, but will run just fine!
