Snipesville, GA | I have a diaphragm pump on our 60 ft sprayer. I can tell you that just putting out 10-12 GPA does great at 8 mph. When you get to the headland and shut off booms the pressure will spike from 35-50 psi to well over 100. That is my bad point on diaphragm pumps. They are positive displacement and what comes in must go out. They are low maintenance and durable however. We usually change diaphragms every other season.
Have you thought about a piston pump similar to a John Blue? We used those many years ago and were very accurate. | |
