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.

Selectable-Flow-Rate Easy-Stroke Drum Pumps for Water and Chemicals
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
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.
Drum Pumps for Fuel and Flammable Liquid
All of these pumps have bonding and grounding wires, while some also have an internal flame arrester, to pump fuel, cleaning solvents, and lacquer thinners.
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.
Steel pumps work with fuels and flammable liquids, but not especially aggressive and corrosive chemicals.
Stainless steel pumps handle aggressive and corrosive liquids that steel pumps cannot.
Pumps for 5-gallon containers have a drum connector that fits Rieke flex spouts and two screw cap adapters: 1 3/4" and 2 1/8".
Repair kits include components such as extension tubes, gaskets, and pistons.

Air-Powered Drum Pumps for Flammable Liquid
These pumps have a motor that is rated for IEC Zone 1, Groups IIB and IIA; and IEC Zone 21, Groups IIIC, IIIB, and IIIA hazardous locations with flammable gases and vapors, so they can be used with liquids such as acetone, ethanol, methyl ethyl ketone (MEK), xylene, and mineral spirits. Motor is nonsparking for use in applications where electricity is unavailable or dangerous. Install an air line filter/lubricator to ensure efficiency and reduce wear on the pump.
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.
