    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.

    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.

    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.

    Pump Pulsation Dampers for Air-Powered Transfer Pumps

    Image of Product. Front orientation. Pump Pulsation Dampers. Pump Pulsation Dampers for Air-Powered Transfer Pumps.
    Absorb pulsation caused by air-powered transfer pumps, reducing wear and preventing damage to inline components such as regulators, sensors, and gauges. Damping pulsation, or vibration, in your pipeline keeps instruments functional and readable. Install the damper as near to the pump’s discharge as possible.

    Stainless Steel Long-Life Air-Powered Drum Pumps for Chemicals

    Image of Product. Front orientation. Drum Pumps. Stainless Steel Long-Life Air-Powered Drum Pumps for Chemicals.
    A stainless steel construction allows these pumps to be used with aggressive chemicals such as methyl ethyl ketone (MEK) and xylene. Also known as diaphragm pumps, they have few moving parts that can fail for a long service life. Install an air line filter/lubricator to ensure efficiency and reduce wear on the pump.

    Long-Life High-Accuracy Metering Diaphragm Pumps for Chemicals

    Image of Product. Front orientation. Diaphragm Pumps. Long-Life High-Accuracy Metering Diaphragm Pumps for Chemicals.
    A 316 stainless steel housing provides corrosion resistance for a long life in harsh environments. These diaphragm pumps meter a consistent amount of liquid within ±2% of the maximum flow. Often used to pump water-treatment chemicals, 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. Do not use with solids.

    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.
