    Polypropylene Air-Powered Double Diaphragm Pumps for Chemicals

    Resistant to chemicals such as ammonia, detergents, and cleaning fluids, these pumps have a Santoprene diaphragm and polypropylene housing. They can be used to move thick sludges and slurries. 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.

    316 Stainless Steel Air-Powered Double Diaphragm 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.

    Plastic Air-Powered Double Diaphragm 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.

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 double diaphragm pumps. 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.

    Aluminum Air-Powered Double Diaphragm Pumps for Fuel and Flammable Liquids

    UL listed for pumping petroleum products and rated for use with flammable liquids, these pumps move diesel fuel, gasoline, kerosene, and mineral spirits. They can be grounded to dissipate static electricity. All have a pressure-relief valve set at 50 psi per UL 79 safety standard. 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.

    Aluminum Air-Powered Double Diaphragm Pumps for Water and Chemicals

    The Santoprene diaphragm resists cracking for a long service life and stands up to water and chemicals such as ammonium hydroxide. These pumps have a rugged aluminum housing for moving large volumes of thick sludges and slurries in demanding environments. 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.

    316 Stainless Steel Air-Powered Double Diaphragm Pumps for Oil, Chemicals, Fuel, and Large Solids

    With a 316 stainless steel housing and a fluoroelastomer diaphragm, these pumps resist a variety of harsh acids and alkalies, such as phosphoric acid, nitric acid, and sulfuric acid. They 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 double diaphragm pumps. 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.
