    Plastic Air-Powered Double Diaphragm Pumps for Water

    These pumps have a chemical-resistant polypropylene housing for use in harsh environments. They 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.

    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.

    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.

    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.

    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.
