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.

Alter the flow rate for versatile dispensing.

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

Including nozzles and connectors, these pumps come with everything you need to start pumping.

A filter/lubricator ensures efficiency and reduces wear on the pump. Often used with hydraulic oil and motor oil in addition to acidic and alkaline liquids, these pumps have a nonsparking motor for use in applications where electricity is unavailable or dangerous.

The polypropylene housing provides good resistance to caustics such as ammonia, electropolishing solutions, and detergents and cleaning fluids.

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

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.

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.

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.
