Apple Roof Cleaning
Roof Cleaning Instructor
There are several reasons why 12 volt roof cleaning pumps fail. A few years ago, I was sought out by the Northern Tool Engineering Team for consultation, and some of my ideas for increased reliability, were incorporated in their line of North Star 12 volt pumps.
I am meeting (again) with the engineers from Northern Tool, who will be here in Florida for the PWNA Convention. They listened to me a few years ago, and incorporated a unique pressure switch from Honeywell, that shuts the pump down more gradually, for longer life. We feel that air pumps are still better, but we suggest the NorthStar 12 volt pumps, for those who wish to use a 12 volt roof cleaning pump system.
I will suggest to the Northern Tool Engineers that they make a version of their pump w/o any pressure switch at all! Their pumps have heavy duty motors rated for no time limit on how long u can run them. Then, you can run the pump with a bypass hose and a pressure regulator that will bypass excess flow and pressure, back into your tank! So, when you shut off the gun, the pump will continue to run, and provide agitation of your roof cleaning mix.
Of course, u best have a good battery, but I say **** a battery, why not simply have a Generator, and a heavy duty 117 to 12 volt power supply, to run your pump
These guys make a 117 VAC to 12 VDC power supply that will do 30 amps all day long for only 60.00! http://www.12voltpowersupplies.us/
Roof Cleaners (in the future) will use low priced AC Generators, that will power these types of power supplies, that will power 12 volt pumps. LOL, charging batteries will soon be a relic of old technology, a remnant of the past! Just as my introduction of air pumps for roof cleaning changed things for us all, so will my new technology suggestions change the way we use 12 volt pumps. 12 volt Pump life will be greatly increased, because there shall be no more of the pumps starving for current from a 1/2 dead battery, that creates unwanted heat, and strain on our pumps. The new generation of 12 volt roof cleaning pumps will run constantly,with 100% of it's voltage and current needs met, and pressure switches, with their sudden stopping and starting of the pumps shall be eliminated.
Once again, I will change the roof cleaning world, and make life better, for all of us
Wisely, the head engineers at Northern Tool have chosen to seek me out again, and to implement my suggestions in their products. I also want to see them offer an optional pump head for their 12 volt pumps made out of KYNAR, instead of Polyproplyne. KYNAR never needs rinsed guys, and has much better UV Resistance as well. I have some other improvements for their engineering team as well, that will make life better for us all, who use 12 volt roof cleaning pumps.
