I don't know, "recreational vehicle" is just the category they sell the
pumps under. You right, its kind of a broad meaning. The one I was
looking at a while back was this; Unfortunately I bought the Shurflo
instead.
http://www.flojet.com/prodInfo/overview/81000-233_ds.pdfI agree that there would be more complexity using nozzles/pump sprayer
as either the nozzles or board must move. The concept I used was fix the
PCB horizontal at the roof of a sealed tank, and have the spray nozzles
direct upwards to the PCB. The nozzles are mounted to a pipe that has
wheels at each end. The wheels run along two tracks mounted at each side
of the tank. Drive mechanism consists of belts and a stepper motor
mounted outside the tank. A pulley and shaft mechanically driving the
tanks internal pulleys. If anyones interested I can take photos and put
then to the photo section at Yahoo Homebrew_PCBs.
