About Process Pumps

About Drum Pumps

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. The motor is totally enclosed fan-cooled (TEFC) for use in dusty, dirty, and damp environments. Pumps are gravity fed and require an elevated liquid source. Do not run dry or use with solids.

Note: If flow control is needed, place valves or reducers on the discharge side; never restrict the inlet of a pump with a valve or reducer.

PTFE Air-Powered Transfer Pumps for Harsh Chemicals

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. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. All can run dry.

Fluid-side maintenance kits include diaphragms, check valve balls, and seals.

Air-motor maintenance kits include seals, O-rings, gaskets, retaining rings, and an air valve spool.

Compact Air-Powered Transfer Pumps

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.

Selectable-Flow-Rate Easy-Stroke Drum Pumps for Water and Chemicals

With Stainless Steel Intake Tube and Housing

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.

Whenever working with flammable liquids, always bond and ground your application for static control. For more information about bonding and grounding, see Sections 1910.106 and 1910.107 of the Federal OSHA Code or see bonding and grounding equipment.

Drum Pumps for Harsh Chemicals

With Spout End

With Nozzle

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.

High-Pressure Air-Powered Drum Pumps for Chemicals

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. Install an air line filter/lubricator to ensure efficiency and reduce wear on the pump.

Foot-Operated Drum Pumps for Harsh Chemicals

Made of PVDF components, these pumps resist harsh chemicals such as hydrochloric acid and sulfuric acid. They have a foot pedal for hands-free operation. A telescoping intake tube works with containers of different heights.

Fixed-Flow-Rate Metering Pumps for Chemicals

Also known as peristaltic pumps and tubing pumps, these maintain a fixed flow rate. Pumps are self-priming, which means they create a suction force to draw liquid upward and fill the pump chamber. Mount them up to 25 feet above your liquid source. All can run dry. Do not use with solids.

Pumps with Tygon 2375 lining resist harsh substances such as isopropyl alcohol and sodium chloride.

Pumps with Viton® fluoroelastomer tubing withstand oil such as gasoline and hydraulic oil.

Flanged Metering Pumps for Chemicals

Commonly used in mining, wastewater treatment, and other systems that require large-diameter hose, these pumps have flanged hose connections. They are compatible with chemicals such as cleaning fluids, acid-washing solutions, and detergents. Pumps have a reverse switch that allows flow in either direction. They are self-priming and create suction to draw liquid upward. They can run dry.

Water Aspirator Pumps

Pick up chemical spills and remove liquids in vacuum filtering systems—these pumps create suction to draw up liquids and gases as water flows through them. They’re made of HDPE and polyethylene, so they won’t break down when exposed to highly corrosive chemicals and acids. The suction end has a barbed tube connector, which attaches to your vacuum tubing. The connector stays attached to your vacuum tubing and connects to the pump when you’re ready to use it again. These pumps also have an internal check valve to prevent backflow.
