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.

Pulsation Dampers for Air-Powered Transfer Pumps

Absorb pulsation caused by air-powered transfer pumps, reducing wear and preventing damage to inline components such as regulators, sensors, and gauges. Damping pulsation, or vibration, in your pipeline keeps instruments functional and readable. Install the damper as near to the pump’s discharge as possible.

Drum Pumps for Harsh Chemicals


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