With a 316 stainless steel housing and a PTFE diaphragm, these pumps resist a variety of acids, alkalies, and flammable liquids such as phosphoric acid, acetone, and methyl ethyl ketone (MEK). They're designed for moving large volumes of thick sludges and slurries in demanding environments.

These pumps have a PTFE diaphragm compatible with oil, fuel, and chemicals such as mineral spirits, methyl ethyl ketone (MEK), and xylene. They have a rugged aluminum housing for moving large volumes of thick sludges and slurries in demanding environments.

With all PTFE wetted parts, these pumps offer the best chemical resistance of all our air-powered transfer pumps and can handle solvents and petroleum-based fluids that PVDF pumps can’t.

The fluoroelastomer diaphragm withstands higher temperatures than a neoprene diaphragm and has better resistance to fuel such as gasoline and kerosene. These pumps have large internal pathways and check valves with flaps to accommodate thick sewage, abrasive slurries, and industrial waste with large solids that would damage standard air-powered transfer pumps.
