Design
FTI Air diaphragm pumps are designed for harsh environments and demanding applications as found in the transfer chemical, aggressive, corrosive or abrasive fluids.
It is also often used in food fluids that requires other characteristics like ease of cleaning, transfer of viscous products without fluid tearing or fluid shearing.
To ensure this high reliability levels, all pump parts operating under pressure are designed and fully tested under FEA regulations (Finite Element Analysis).
Air Valve — Highly Efficient, Rugged and Simple Design
Painted die cast aluminum or glass fiber reinforced polypropylene plastic valve body options for standard or corrosive atmospheres
Low friction carbon filled PTFE slide valve on the polished alumina ceramic valve plate allows for longest life and superior sealing eliminating air leakage. It also eliminates high cost seals moving over holes, as needed on many competitors’ valves.
Molded Buna gasket is fitted to grooves in the face of the valve body and slide valve plate to ensure total sealing and eliminate flat gasket tearing.
Uses air through slotted diaphragm shaft to shift the valve eliminating need for separate pilot valve or mechanically operated pilot valve. Fewer parts, simpler design and less prone to failure.
Non-stalling design – air valve cannot stall in any position
Outside mounting assures easy access for inspection or maintenance – valve can be removed and serviced while pump is still installed
Lube free design eliminates the need for packing grease or lubricated air
Fewer parts reduces maintenance time and costs
All components are individually replaceable to easily restore the valve to brand new condition.
