    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.

    Continuous-Duty Any-Direction Constant-Flow-Rate Diaphragm Pumps for Water and Coolants

    Image of Product. Front orientation. Diaphragm Pumps. Continuous-Duty Any-Direction Constant-Flow-Rate Diaphragm Pumps for Water and Coolants.
    Rated for continuous use, this diaphragm pump is often used to move caustics such as antifreeze and salt water. Mount it in any position, even upside down. It is typically used for low-flow spraying, draining, and washdown applications. The pump is self-priming, which means it creates a suction force to draw liquid upward. Pump can run dry and does not require an initial fill, so it’s a good choice for applications without a constant flow of liquid. Do not use with solids.
    Pressure Switch—Pumps with a pressure switch automatically shut off the pump at the maximum pressure.

    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.
    Repair Kits—Repair kits include a pump head assembly, a diaphragm, valves, and seals.

    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.

    Smooth-Flow Air-Powered Double Diaphragm Pumps

    Also known as sprayer pumps, these provide a smooth, uniform flow for agricultural spraying, soap dispensing, and chemical transferring. They automatically turn on when you open the outlet valve. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. Do not 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.
    Repair Kits—Repair kits include a pump head assembly, valves, a diaphragm, and mounting hardware.

    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.

    Miniature Metering Diaphragm Pumps for Chemicals

    Image of Product. Front orientation. Diaphragm Pumps. Miniature Metering Diaphragm Pumps for Chemicals.
    With a footprint that's only a few inches in any direction, these diaphragm pumps fit into compact systems to dispense small amounts of acids, cleaning fluids, and other chemicals. They're often used in sterilization, photochemical, and water treatment systems. Choose from pumps with either a 4-20mA or 1-5V DC input signal that controls the flow rate.
    Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot 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.
