12 v pump

Looks like the same type roller pump used in gas applications,..I didn't even know they made them to run off 12V. The description states "Also available in Poly and PTFE" If I were to try one it would be one of these,..as I assume the one that one that here is cast iron,..which I wouldn't even consider using for SH use AT ALL,..Especially at this cost. Assuming the one shown is cast,..and it is $586.00,.. I can only imagine the Poly or PTFE (Teflon) are quite a bit more but would be the only choice to even try.

*Would also need to be plumbed with a by-pass

**The gas roller pumps run at around 150 PSI for the same GPM rating as this one,.which is only 60 PSI. Would be nice to have the Poly and PTFE roller available to mate up to a gas engine.

***I used to use the cast iron roller pumps a long time ago,..they did spray well but just didn't last,..but they only cost around $90.00 each.

What ends up failing on these pumps is the pin the rollers ride on. If it is steel then it will fail quickly, if it is stainless it might last a little longer but not by much
 
I think you'd be way better off getting a fatboy or better yet just downstreaming with a power washer. I can't imagine rinsing with a 60 psi...we have to bust out the brush or magic erasers too often with our 400 psi rinse machine.
 
Yeah rinsing would suck, it does have volume but the pressure isn't there so you really couldn't move much.
A 4gpm pressure washer would be faster.
If you really want electric then you could go with a booster pump and power it with a generator (kinda defeats the whole electric only thing), a inverter or simply plug it into the customers house.
Boosters aren't cheap and they won't last forever either but they will last longer than the roller pump
 
A minimum of 4 gpm belt or gear driven machine is much better versus just 12v pumps. I have multiple 12v pumps and they have their place however, doing larger surface areas, It's hard to beat D'Sing and rinsing with the same machine. When you run a J-Rod with the high and low application tips you have the best of both worlds and the pressure washer pump (if taken reasonable care of) will far outlast any 12v pump.

Coupled with an injector bypass kept close(70-100ft) to the operator gives you the best of both worlds and will also provide just plain rinse water with full flow when needed. Keep several tip sizes handy which allows quick changes of pressure for the times when you need a little more psi for those "up high" tough spots.
