A new model of non-metallic AODD pumps
The new FTI Air FT025 1/4-in. air-operated, double-diaphragm (AODD) pump is manufactured from unfilled polypropylene (PP), unfilled polyvinylidene fluoride (PVDF) or conductive carbon-filled PP and features Santoprene or polytetrafluoroethylene (PTFE) diaphragms for maximum chemical compatibility. It offers 5.8 gal/min (22 L/min) maximum flow. The new 1/4-in. AODD plastic pump features a unique lubrication-free, non-stalling air valve that is simple, rugged and reliable, requiring no separate or mechanical pilot valve. The air valve contains fewer parts than alternatives, reducing maintenance time and costs. The pump also features a durable stainless-steel airline connection for maximum reliability. The FTI Air Model FT025 pump works with many fluids, including acids and bases, plating solutions, wastewater and solvents. — Finish Thompson Inc., Erie, Pa.
