    Just thinking outloud here. Since I have several lawn garden tractor verticle shaft motors (18-20 hp mowers gave up long before the engines)around I was wondering if any of the pump manufacturers make a commercial pump that has the shaft verticle instead of horizontal. It would seem that they would. I assume that most if not all pumps currently has to have the shaft horizontal. Anyone else ever wonder about these things?

    Jerry or anyone smarter than I, which is probably most if not all reading this. I have finally got around to working on this little project and have a question about the buffer tank. Jerry and others has said since this is a direct drive pump I need a good supply for it. Here is what I hope will work ( just a mock up of what i have in mind). Take a sprayer tank(15 gallon , the one in photo is a 26 gallon) and set it up on a rack higher than the pump itself and use a short 1" supply hose(red in picture) to the pump. Bypass back to the tank. Under the rack would be storage for chemical tanks and jugs. I would have a float valve to keep the tank full when on site but would not have to drive around with it full.

    1- Will this supply enough head pressure for a 3500 psi 3.5gal min pump to keep it from starving?

    2- Will 15 gallons be enough bypass capacity to keep the pump from over heating if not spraying for several minutes?

    3-Jerry had mentioned dual feeding the pump, I assume this means feeding from both inlet ports, so would I remove the thermal relief valve. And where would I put that?

    4- If all of the above is ok, where is a good source for bulkhead fittings?

    Thanks, Robin

    Choose a tall tank, to maintain good water-feed to the head of the pump.

    the easier the pump gets water, the longer the seals last (especially with a "high-speed" pump,)

    and you also benefit from it having a small footprint.

    we have a 44gl tank with 14 x 26" footprint. and there are float valves work fine

    ..as they bounce down the road.

    you don't have to dual feed a 4gpm pump, but use at least 1" feed line,

    with no "flow restricting" fittings.

    Jerry,

    So, do you think a 55 gallon drum would work, I was thinking of laying it on the side, but if I need the head pressure with it standing up that's what i'll do. Also when you mention duel fed do you meen feeding the pump from both inlet sides at the same time? If so would that help if I did use a shorter drum/tank?

    I picked up a portable mi-t-m 3504 hot water pw for a good deal. I would like to mount this on a trailer with a buffer/float tank. Since the burner turns on and off in accordance with when the trigger is pulled, when I plumb the bypass backto the tank will the burner continue to burn? Not sure how the pressure sensor in the pump works. I will be using a small buffer tank (50-70 gallons).I don't want the burner to continue if no water is going through the coils. Any help would be appriciated.
