FDA compliant air operated double diaphragm pump

28 May 2018

The Finish Thompson FTI AIR range of air-operated double diaphragm pumps (AODD) has been expanded following the introduction of new models in materials which are FDA compliant. Available in the UK from Michael Smith Engineers, these new pump options are made from polypropylene and 316 stainless steel making them suitable for use in food and beverage fluids handling applications. 

The FDA compliant metallic option features 316L stainless steel wetted components and a smooth satin finish to RA 200µ-in/5.1µm with tri-clamp connections and stainless steel hardware. The non-wetted parts are available in either powder coated aluminium or polypropylene.

An ATEX certified option is also available on request.

Both models have an integral, stall-free air valve that eliminates the need for a separate pilot valve, or mechanically operated pilot valve. The components for this include a low friction slide valve on a ceramic plate to allow for long-life and superior sealing, a moulded Buna gasket which ensures total sealing and eliminates flat gasket tearing.

The design places the emphasis on fewer moving parts, resulting in the all-important benefits of improved reliability, reduced downtime and lower running costs.
