McNeilus Dual Diaphragm Pump

McNeilus Dual Diaphragm Pump

This Sandpiper 1-inch air-operated double diaphragm (AODD) pump is an OEM replacement for McNeilus and Con-Tech rear discharge mixer water systems. It features an aluminum housing with Buna-N (Nitrile) diaphragms and ball valves, providing excellent durability and chemical resistance. Capable of delivering up to 45 GPM, this pump pressurizes the mixer's water tank system to supply up to 90 PSI of water pressure at the rear of the truck for efficient washdowns. Its self-priming, seal-less design allows it to run dry without damage and handle suspended solids up to 1/4-inch in diameter.
