Small enough to fit in the palm of your hand, these pumps transfer water, detergents, and chemicals. They have a chemical-resistant polypropylene housing. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. Pumps can run dry.

Pumps with fluoroelastomer diaphragm are also suitable for use with fuel and oil.

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.

Santoprene diaphragm stands up to ammonia and resists cracking for a long service life.

Rated for continuous use, this pump is often used to move caustics such as antifreeze and salt water. Mount it in any position, even upside down. Also known as a diaphragm pump, it is typically used for low-flow spraying, draining, and washdown applications. Pump has a pressure switch that automatically shuts off the pump at the maximum pressure. It 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.

The polypropylene housing provides good resistance to caustics such as ammonia, electropolishing solutions, and detergents and cleaning fluids. Also known as diaphragm pumps, they have few moving parts that can fail for a long service life.

Choose a pump with a PTFE diaphragm for superior resistance to a wider variety of concentrated chemicals than Santoprene. Install an air line filter/lubricator to ensure efficiency and reduce wear on the pump.

Repair kits include components such as O-rings, valves, balls, and diaphragms.

A chemical- and impact-resistant PVDF housing stands up to 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.

Repair kits include O-rings, valves, and diaphragms.

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

Styles C-F are rated for liquids up to 2,500 centipoise. Style C are often used as hand pumps and do not come with a connector. To attach them to a container, select an optional connector.

Designed to move low volumes of caustic liquids in confined areas, these pumps have a thin intake tube and a small handle. They are often used to pump cleaning fluids, acid-washing solutions, and bleach.

Style A pumps have a selectable flow rate, so you can adjust flow for different dispensing applications.

Style B pumps have a flexible discharge spout.

Made with PTFE components, these pumps stand up to aggressive chemicals our other drum pumps can't, such as hydrochloric acid, bleach, sodium hydroxide, and methyl ethyl ketone (MEK). A stopcock prevents fluid and vapor from leaking after use.

Since these pumps use suction to draw liquid out of your container, they continue dispensing once you get them started. They're often used with coolant and water.

Adjust pumps with a 5-7 gpm flow rate for different dispensing applications.

For accurate dispensing in extremely low-flow applications, adjust flow in 2% increments. These pumps are compatible with chemicals such as ammonia and etching and cleaning solutions.
