Mix-N-Fill Tank in the Shop ?'s

    Does anyone have what I refer to as a "mix-n-fill" tank in their shop? I will try to explain what I am talking about in case you refer to this as something different.

    We currently fill the tanks on our trucks with water, and then in a separate instance we will pump liquid fertilizer into those tanks. This has to be done each time the truck is empty. I would like to have say possibly a 1000 gallon (or larger depending on recommendations from you) that we could have in the shop that would allow us to mix the water and chemicals needed. Then we would be able to pump directly from here into the truck all at the same time. I know that there will need to be some form of an aggitation pump in the tank to keep the wwater and chemicals from separating.

    Do you have pictures of what you do? Do you know what type of pump would work for this scenario?

    Also, do you know where I can find a gauge that can go onto a pump hose to calculate the gallons of flow through the hose and into the pump? I know t hey have them for fuel tanks, but I have been told that the chemicals will corrode these particular gauges. Do they make them specifically for chemicals?

    Thanks in advance for your assistance!

    What about risk. I am not sure your state pesticide regulators would like this situation. And they would probably demand a big dike system under the tank in case of spills or leaks. And in Michigan they would insist on a rinse and fill pad to catch any spills coming from the truck. Agitation is a problem. How much time would it really save?

    We used a big tank of plain water at Tru Green for a while. Filled the tank slowly overnight. When filling the trucks, a pump could pump a hundred gallons per min into the truck tank. Quick. We then added fert and weedo. (or add the fert and weedo first--then add water).

    Honestly, do not know how much time it would really save. This is the feedback that I am looking for to see how many people do this and what they think. I know that we will need a spill area for this, and have added that into the plans.

    Any other thoughts?

    A longer mixed time makes the water pH more imporntant. If the pH is bad then degredation starts right away.

    I'm not sure of your volume / time between refils but if it is too long you might be loosing effectivness.

    I have talked to a couple TG guys out here that had no idea what they were spraying. Hopefully your guys wont get lazy and just spray whatever you mix in the tank... It might save time if you have multiple crews waiting to fill up.

    Riggle,
    You mean you fill it half way, then added the chemical... then finish filling.. right? lol just teasing.

    I mix on the ground but only 200 gallons at a time. I use a 110 V Swimming Pool recirculating pump that puts out 50 GPM. I am sure it can mix a 1,000 gallon tank. But mixing more than you use in a day is no good.

    Thanks for the feedback.

    The way it sounds it will be better for me to fill as we go. We spray on average 250 gallons a day. Probably not a lot compared to most of you.

    On the swimming pool pump for recirculation, does the pump hold? Do the chemicals corrose the inside motor?

    SLC,

    For me...I think "mixing on the go" is the only way for me! Don't want to carry high gallons of mix incase of an accident. Much easier to clean up a few gallons of conc vs large premix.

    Are you walking or riding?

    You state you use 250 gallon/day. That sounds like alot of water to me for a ride on but if walking then I don't know!

    I only use about 100-120 gallons of water/day a day and cover around 10 acres (on an avg day).

    Just a tip...make sure you are not using "too much" water.

    Water is your enemy as your weed control will be just as good with low volume apps!
