Can anyone suggest a particular roller pump for chlorine "no pressure" roof cleaning?

Most that go that route use a Hypro. It's O.K. but was never mean't for any sort of bleach. If they're rinsed they'll last a while, but like ShurFlo's they will eventually fail. I've tried them and didn't like the re-occurring expense of gas/oil/pumps, etc. Being gas-powered, they're also louder. For the $, ShurFlo is the way to go in my opinion. Not necessarily knocking the rollers, just not for me.

You can buy a cheap, simple roller pump set-up at Tractor Supply.

That's Jimmy Buffett........I'm not quite that old....Yet! LOL!

You're not the first to make that assumption. The wife and I are huge fans of his and try to make it to at least one concert a year.

Hopefully Mel (PWKid) will chime in here...he uses a gas powered pump setup, but it isn't a roller pump. A bit more expensive, but it is built to stand up to the chlorine. I'll likely go this route at some point for those roofs that I can shoot from the ground. As with the Xjet, the shurflo has its uses, but in some cases a higher volume, higher psi pump makes things a heck of a lot easier.

I use a gas powered John Blue pump,that is made out of hasteloy.It is a new design for them and it is a prototype at the moment.I was asked to use and abuse this pump.I use it for roof cleaning and it gives me 5.0 gpm @ 250 psi.I have used every kind of chemical pump imaginable.Roller pumps didn't last I was using 1 a month or so,shureflo lasted the longest but didn't give me the psi I was looking for. I have had this john blue pump for 5 months and no problems at all and I pump 12% through it without a flaw.(knock on wood)

I'm glad to see more info still coming in! I appreciate the help. I've used Sureflo and Flojet since 1995 and never looked into other options for cleaning roofs without pressure.

I use a gas powered John Blue pump,that is made out of hasteloy.

It is a new design for them and it is a prototype at the moment..

.. 5.0 gpm @ 250 psi. I have used every kind of chemical pump imaginable.

Roller pumps didn't last I was using 1 a month or so,

shureflo lasted the longest but didn't give me the psi I was looking for...

I have had this ..for 5 months and no problems at all and I pump 12% through it without a flaw.

this is a Diaghram style pump..

these are THE BEST "type" of pump, as the diaphrams are very chem-resistant,

available in several materials, and the fluid-end is usually epoxy-coated..

..very chem-resistant.

Also know.. as engines are coming out with beefier charging systems, and you'all are learning to use beefier batteries, beefier cables, and properly fusing 12 volt widgets..

you'll see more "worthwhile" pumps come out in 12 volt versions..

the Mfr's are learning (slowly-but-SURE-ly) that there's a larger than ever community here.

Be sure to tell your preferred-venders to "watch for" these new upgrade tools.

remember.. I'm not selling this stuff..

I'm just trying to be a technical-assistance here, with un-biased opinion.

..and.. your suggestions will "matter", as a new, stronger, more functionally-correct association is formed,

which WILL have the balls to funnel you needs, as an group, to the manufacturers.

this is how an industry is "supposed" to grow. Eh?

..technology comes from the jobsite.

... maybe Delevan will come up with a specially-coated version,

for "better" chem-resistance,

but the pump is generally made with "limited lifespan, due to the fast-wearing rollers.

you (cleaning-guys) should be striving for "Long-Term-Low-Cost" Eh?
