These pumps have the best chemical resistance of all our circulation pumps. Instead of a shaft seal, they use magnets to turn the impeller, reducing wear and leakage.

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.

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.

All of these pumps have bonding and grounding wires, while some also have an internal flame arrester, to pump fuel, cleaning solvents, and lacquer thinners.

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 stainless steel construction allows these pumps to be used with aggressive chemicals such as methyl ethyl ketone and xylene.

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