Finish Thompson Inc. (Erie, PA) has added a new model to its line of non-metallic air-operated double diaphragm (AODD) pumps. The new FTI Air FT025 1/4” AODD pump is manufactured from unfilled polypropylene, unfilled PVDF or conductive carbon-filled polypropylene and features Santoprene or PTFE diaphragms for maximum chemical compatibility.
The new 1/4” AODD plastic pump features a unique lube-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 other options on the market, 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 fluids including acids and bases, plating solutions, wastewater, and solvents. The design of the pump is quiet, rated at only 65.3 dB(A), and has versatile suction and discharge connections – with both 1/4” FNPT/FBSPT and 3/4” MNPT/MBSPT internal and external connections as standard. It’s backed by a five-year manufacturer’s warranty.
