viewrenew Report post Posted October 25, 2017 I’ve picked up a decommissioned lawncare box truck that has a PTO shaft with pulleys that used to drive sprayer pumps. The pumps are gone and from what I’ve read, they use Hydra-cel 25 pumps that were “roundup ready” and cost about $ 3,500 brand new. I saw these Delavan Diamond SS pumps for $389 - Viton seals. http://www.sprayerdepot.com/Sh…/Delavan-Roller-Pumps/8900DSS Should I go this route? Rather have two of these pumps for $700 instead of two $5000 pressure washers I do plan on installing a pressure relief valve to bypass the hose while I’m not spraying ...though any recommendation on how to set this up inline to return to the tank? Thank you! Share this post Link to post Share on other sites
Apple Roof Cleaning (813) 655-8777 Report post Posted October 25, 2017 Sorry to spoil the party, but the Delevan roller pump with any kind of rollers will NOT stand up to the SH! I speak from actual experience. The SH attacks the inner chamber, changing the clearance of the rollers, causing loss of flow and pressure. Talk to me, what are you wanting to do mostly, clean roofs, or pressure wash ? Share this post Link to post Share on other sites

I am also strongly considering learning how to clean/treat cedar roofs. I have surface cleaners and a 10gpm pressure washer now, but the 24gpm flow has me very intrigued. The truck I have has everything in place to mount PTO pumps, So I figure I'll look into this possible setup and save a lot of money for a more efficient system if possible.

I was planning on metering down the flow if necessary. But higher flow rate for rinsing house washes would be great. And right now, anything would be better than my delavan fatboy setup. It's all about twice the (properly performed) work in half the time, right? Share this post Link to post Share on other sites

A pressure washer can be run from a PTO, and Lori can set you up with one. That is what to use to rinse with, as well as house wash with by downstreaming, OR you can house wash with the all flow, then rinse with the pressure washer.

Are you more concerned about plumbing? Is it just a simpler plumbing job with the two systems? Share this post Link to post Share on other sites

Because the all flo will never rinse like a decent pressure washer, and besides, you really need a pressure washer in the exterior cleaning business Plus, you already HAVE the PTO, so you can run a badd ass pressure washing pump Share this post Link to post Share on other sites

Many want a high GPM pressure washer, but can't afford it, because the motor required to run an 8-12 gpm pressure wahser isn't cheap. Your PTO will run any pressure washing pump, but remember this, for any pressure washer much over 4-5 gpm, you will need a water tank. Trying to run a high GPM pressure washer on tap water isnt good, and often the pump will suck the hose dry Share this post Link to post Share on other sites

It has three large tanks properly mounted - two 325 gallon tanks and one 250 gallon tank. I figure one for water, one for bleach...maybe set up a proportioner for straight roof application without a mix tank? And the third tank may be for gypsum/lime solution...though I read recently that you're not in the gypsum camp 1 Apple Roof Cleaning (813) 655-8777 reacted to this Share this post Link to post Share on other sites

All will be good for water, but not all will be good for SH I learned this the hard way, when the tank started coming apart. The Pro Portioner imho is a good investment. LOL, I have cleaned well over 25,000 roofs in nearly 30 years of doing this and NEVER used Gypsum or Lime. Water, and lots of it, applied to the plants as soon as the shit starts dripping on them is all you need. Always remember, dilution is the answer to pollution I can tell you why I don't like using Lime and Gypsum, but it is a technical explanation. Share this post Link to post Share on other sites
