I run them on one of my systems. Work great. They are air operated. I run them anywhere from 100 psi down to 20psi if I am spraying small areas of deck or concrete. I run roof chems and oxalic thru them and not a problem. I have two of them set up so if I need to spray a little further, I run both at the same time.
I replaced my 12v pump with this model. It works great and can be run at any PSI up to 100. I run mine with a small electric compressor on board. I added a 2000w power inverter to the battery bank to run it.
Has ran twice as long already than the 12v pump.
