Finish Thompson Inc. introduced the FTI Air FT30P, a 3-inch plastic air-operated double diaphragm pump designed for industrial fluid handling. The pump features a stall-resistant air valve that eliminates the need for pilot valves, supporting consistent cycling and reducing wear.

Polypropylene wetted components provide resistance to alkalis and strong acids, while configurable diaphragm, ball and seal options allow compatibility across a range of chemicals and temperatures. Bolted construction and molded chambers support leak-free operation over time.
