Soap Solutions Pumps | McMaster-Carr

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.

Fixed-Flow-Rate Metering Pumps for Chemicals

Also known as peristaltic pumps and tubing pumps, these maintain a fixed flow rate. They're often used with chemicals such as bleach and acid solutions. 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 that pumps with unlined Tygon tubing do not, such as isopropyl alcohol and sodium chloride.

Remote-Adjustment High-Pressure Metering Pumps for Chemicals

Automatically control output from a distance using a variety of analog and digital signals, including 4-20mA and external pulse signals. Pumps can also be controlled manually, run on a schedule, or set to cycle on and off. View flow rate on the LED display. These pumps handle pressures four times higher than standard pumps. They meter a consistent amount of liquid within ±1% of the maximum flow. Often used in boiler feed systems and water treatment, they're compatible with chemicals such as cleaning fluids and acid-washing solutions. Pumps are self-priming and create suction to draw liquid upward. They can run dry.
