    Does anyone use a John Blue DP 139 pto driven pump for lawn spraying? I have a Hydra-Cell that has been rebuilt 4 times, I am chucking it. Curious if anyone has used John Blue

    Thanks for your replies

    The diaphrams keep blowing allowing chemical into the oil side of the pump. I picked up this truck at dealer who buys fleet trucks turned in after lease, the pumps were both blown. I rebuilt one, it blows the diaphrams sometimes 3 minutes after rebuilt, sometimes 30 days. I have talked to the factory, and some other people who rebuild them. I don't remember who, it's been a year since I looked into this. I am tired of spending 300 plus for a rebuild kit, and following instructions to a T and having it blow again. Soooo, I am off to another brand, unless I can find someone who can once and for all, tell me what the problem is,
