    I'm looking at skid sprays and was wondering what are the advantages of a diaphram or a piston pump.

    I was considering a 200g gnc. We are currently using back pack Pre and post herb., and insecticides and are ready to upgrade. We only do about 60 8-10k lawns 3-4 times per year currently. Do you think a 200 gallon would be to much. The skid will be in a 1/2 ton pick up. Thanks for your help.

    That's what I'm hoping. Just not sure about the pump types diaphragm or piston and the tank sizes. What's you opinion?

    A good piston pump will last a long time if your just using the sprayer for liquid
    pesticides. Diaghram pumps do better with wettable powders :waving:

    Diaphragm pumps will also forgive you if you run the tank dry. I actually have a CAT1010 pump. What keeps me from putting this 13 GPM 700 PSI beast in operation is the concern that if I am at the end of the 300 ft hose, I cannot run fast enough to shut down the pump before the piston seals implode. 100 yards, if I could run that fast enough, might not even be in the spraying business. Now if I had some kind of wireless clicker in my shirt pocket that could shut down the pump remotely................

    I prefer diaphragm pumps.
    However, many years ago we used John Bean pumps at TruGreen. Ceramic cylinders. Sometimes lawn techs would forget to open the main valve on the suction side of the tank. Not good--got a little hot--no damage that I recall.
