But I know jack squat about them other than the fact that I can use a tiny engine to get crazy volume… I’m trying to build a cold water house washing workhorse for the trailer, and was thinking I could go this route… but honestly I’m not even sure if any of the workings are the same. Is the unloader different, is the diwnstreaming method itself with those things different? I’m lost lol… thoughts ?
They’re mainly used for roof washing setups. @Racer has a gas roof pump, @florida_condo_cleani runs AODD setups I believe.
It’s low pressure so no unloader. Basically replaces a 12V.

There great things for rinsing. There’s many pros and cons. Obvious being the volume capability, they go from about 5 gpm all the way up to over 50gpm for the 6 diaphragm models. All this great volume needs to come from somewhere and it ain’t a residential spicket. Depending on model and size of pump there a little overkill for chemical applications even on roofs in my opinion. There not really designed for our industry and the chemical quantities we need to clean something, there mainly used for chemical spraying where booms are involved and acres need to be covered in sauce with what we would commonly call a batch mix. If hydrants, 5+ story building washes and massive parking lot rinsing were my bread and butter I would use them in a heat beat, for residential and general commercial I’m not sure I would.
