FDA-approved Air Operated Double Diaphragm (AODD) Pumps

Overview

FTI AIR is a comprehensive line of air-operated double diaphragm pumps meticulously designed from the ground up, using state-of-the-art computer-aided design resources. Every pump component was run-tested continuously for many hundreds of hours at Finish Thompson and in field tests during development, resulting in one of the most reliable, rugged and affordable air-operated double diaphragm pumps on the market today.  As well as a complete range of polypropylene, PVDF, aluminium and stainless steel models, the FTI AIR portfolio includes FDA compliant wetted material pumps (stainless steel and unfilled polypropylene), and ATEX versions.

ADVANTAGES

The FTI AIR series of air operated double diaphragm (AODD) pumps have many benefits over other pump technologies:

• Simple installation
• Easy to operate and run
• Portable
• Self-priming
• Submersible
• Dry running
• Can pump dirty liquids or liquids with particles
• Abrasive liquid handling
• Viscous fluid pumping
• Can pump shear sensitive liquids
• Affordable compared to other positive displacement technologies
• Low maintenance and running cost

FTI AIR design also incorporates its own additional unique features including a lubrication-free, non-stalling air valve, ideal for numerous applications and environments. The air valve contains very few components compared to other air valves in the market, reducing servicing time, maintenance costs and downtime.

Every pump is tested prior to packaging and shipping,
