½” Pneumatic Double Diaphragm Pump

Samoa ½” AODD Pump, DF50, Dual Inlet PP-Hytrel-PTFE

Extremely small and durable diaphragm pumps for dosing, spraying, and dispensing a range of fluids. Maximum flow rate is 50 l/min. A polypropylene air motor is used in polypropylene pumps. Transferring and distributing windshield washer and antifreeze solutions are typical uses for these pumps. They can be utilized in distribution systems with hose reels as systems pumps or as stand-alone pumps for transfer applications. For 1:1 ratio mixing of fluids with comparable viscosities, such as windshield wash or antifreeze with water, pumps with multiple inlets are available. Each dual inlet pump has two inlets that are 3/8" BSP (F).
