Sprayer diaphragms,

I have a John Deere trailed sprayer and it’s on its second set of diaphragms this year, having done 5-6000 acres since they were replaced in the spring. It’s not left with spray solution in the tank overnight and washed out using the rinse cycles after every days spraying,
Any ideas what the crack is with it?

Sprayer guy (probably from the same place given our location) also told me don’t use eco pto as the higher start up speed doesn’t help.
So that rules out using the pto as the the shut off and on in field work.
ive found using the pto instead of the electric that the desired flow rate has always come up much quicker when setting into work.

IME, there are two thing that damage pump diaphragms. Number one is cavitation when you run the pump with it starved of liquid either by turning the master suction tap off or a blocked suction filter etc. The second is over speed. Chassing the tractor down the road with the PTO in 540E or even better 1000 will bugger them up very quickly whatever the make of pump.
