316 Stainless Steel Air-Powered Transfer Pumps
for Chemicals, Fuel, and Flammable Liquids
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. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. All are submersible and can run dry.
Fluid-side maintenance kits include diaphragms, check valve balls, and seals.
Air-motor maintenance kits include seals, O-rings, gaskets, retaining rings, and an air valve spool.

Aluminum Air-Powered Transfer Pumps for Oil, Chemicals, and Fuel
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. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. All are submersible and can run dry.
Fluid-side maintenance kits include diaphragms, check valve balls, and seals.
Air-motor maintenance kits include seals, O-rings, gaskets, retaining rings, and an air valve spool.

Plastic Air-Powered Transfer Pumps for Fuel and Flammable Liquids
These pumps can be grounded to dissipate static electricity and are rated for use with flammable liquids such as gasoline, kerosene, isopropyl alcohol, and mineral spirits. All are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. Pumps are submersible and can run dry.
