The Hypro D1064 is a 4-diaphragm pump intended for pumping and spraying herbicides, pesticides, liquid fertilizers and other hard-to-handle liquids. The Hypro D1064 can be purchased by itself (9910-D1064) or purchased with a gearbbox (9910-D1064GRGI) so it can mount onto 18HP gas engines. Also, Hypro D1064 Repair kits, 1642 Gear Reduction kits and a VDR50 Control unit are available for your Hypro D1064 to keep the pump in excellent working order.
