    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.

    PTFE Air-Powered Double Diaphragm Pumps for Harsh Chemicals

    With all PTFE wetted parts, these pumps offer the best chemical resistance of all our air-powered double diaphragm pumps and can handle solvents and petroleum-based fluids that PVDF pumps can’t. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. All 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.

    Air-Powered Double Diaphragm Pumps for Food and Beverage

    Made of FDA listed materials for use with food and beverage, these pumps have a sanitary quick-clamp fluid connection for easy cleaning. They are commonly used to move sauces, concentrates, and other thick liquids with solids. 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.

    Use these diaphragm pumps for high-pressure output of antifreeze, hydraulic oil, and motor oil. They have an internal relief valve to prevent pressure buildup. The adjustment dial alters flow rate in 1% increments of the maximum flow. Pumps have a totally enclosed fan-cooled (TEFC) motor for use in dusty, dirty, and damp environments. Do not run dry or use with solids.

    High-Accuracy Metering Diaphragm Pumps for Chemicals

    Image of Product. Front orientation. Diaphragm Pumps.
    These diaphragm pumps meter a consistent amount of liquid within ±2% of the maximum flow. Often used to pump water-treatment chemicals, cleaning fluids, and electropolishing solutions, they have an adjustment dial that alters flow rate in 2% increments of the maximum flow. Pumps are self-priming and create suction to draw liquid upward. They can run dry but are not for use with solids.

    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 Fuel, Oil, and Large Solids

    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 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.

    Aluminum Air-Powered Double Diaphragm Pumps for Oil and Chemicals

    A neoprene diaphragm resists oil and chemicals such as isopropyl alcohol and deionized water. These pumps 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.

    Aluminum Air-Powered Double Diaphragm 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.

    Aluminum Air-Powered Double Diaphragm Pumps for Oil, Chemicals, and Large Solids

    A neoprene diaphragm stands up to oil and chemicals such as isopropyl alcohol and deionized water. 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 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.

    Plastic Air-Powered Double Diaphragm Pumps for Oil

    A Buna-N diaphragm stands up to lubricating oil such as motor oil. These pumps are designed to handle thick sludges and slurries. They have a chemical-resistant polypropylene housing. 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.

    High-Pressure Metering Diaphragm Pumps for Chemicals with Locking Lever

    Image of Product. Front orientation. Diaphragm Pumps. High-Pressure Metering Diaphragm Pumps for Chemicals with Locking Lever.
    An adjustment dial with a locking lever allows for easy flow control. These metering diaphragm pumps can be used with pressures up to four times higher than standard chemical metering diaphragm pumps. They're often used for general purpose dispensing of chemicals such as ammonia and acid-washing solutions. The adjustment dial alters flow rate in 5% increments of the maximum flow. Pumps are self-priming and create suction to draw liquid upward. Do not run dry or use with solids.

    Automatically control output from a distance using 4-20 mA or external-pulse signals. View the flow rate on the backlit LCD. These diaphragm pumps meter a consistent amount of liquid within ±2% of the maximum flow. Often used to pump water-treatment chemicals, cleaning fluids, and electropolishing solutions, they have an adjustment dial that alters flow rate in 2% increments of the maximum flow. Pumps can run dry. Do not use with solids.
