A 316 stainless steel housing sealed with fluoroelastomer resists mild chemicals and acids, such as coolant, oil, and phosphoric acid.

Rated for continuous use, these pumps are often used to move caustics such as antifreeze and salt water. Mount them in any position, even upside down. Also known as diaphragm pumps, they are typically used for low-flow spraying, draining, and washdown applications.

With all PTFE wetted parts, these pumps offer the best chemical resistance of all our air-powered transfer pumps and can handle solvents and petroleum-based fluids that PVDF pumps can’t.

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.

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 transfer pumps.

These pumps have a selectable flow rate, so you can adjust flow for different dispensing applications. A lever handle maximizes output with each stroke for low-effort dispensing.

Push the plunger to pump water, cleaners, and chemicals.

A 316 stainless steel housing makes these pumps resistant to coolants such as ethylene glycol.

Eliminate leaks and waste with a faucet-style nondrip nozzle that quickly starts and stops flow.

Often used with ammonia, etching and cleaning solutions, and other caustics, these pumps have a nonsparking air-powered motor for applications where electricity is unavailable or dangerous.

These pumps have a motor that is rated for IEC Zone 1, Groups IIB and IIA; and IEC Zone 21, Groups IIIC, IIIB, and IIIA hazardous locations with flammable gases and vapors, so they can be used with liquids such as acetone, ethanol, methyl ethyl ketone, xylene, and mineral spirits.

With a higher pressure than other air-powered drum pumps, these pumps move thick chemicals with a viscosity of up to 5,000 centipoise. A stainless steel housing stands up to acids, solvents, and other caustics.

A chemical- and impact-resistant PVDF housing stands up to aggressive chemicals such as methyl ethyl ketone and xylene.

Drain and transfer liquid more quickly and easily than hand-operated pumps and siphon pumps.

Designed to move 40 gallons of liquid per minute, these pumps quickly empty drum contents.

For accurate dispensing in extremely low-flow applications, these pumps allow you to adjust flow in 2% increments.

Also known as peristaltic pumps and tubing pumps, these maintain a fixed flow rate.

Commonly used in mining, wastewater treatment, and other systems that require large-diameter hose, these pumps have flanged hose connections and large diameter tubing.

These pumps can be used with pressures four times higher than standard pumps for chemicals.

For high-volume chemical sampling and draining, these pumps have a powerful motor that enables them to move 2,448 gallons of liquid per day.

Automatically control output from a distance using variety of analog and digital signals, including 4-20mA and external pulse signals.

With a footprint that's only a few inches in any direction, these 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.
