About Process Pumps

About Drum Pumps

Self-priming up to 6 ft., these pumps have a stainless steel housing sealed with PTFE to resist chemicals such as ammonia and detergents as well as harsh solvents including methyl ethyl ketone (MEK). The motor is totally enclosed fan-cooled (TEFC) for use in dusty, dirty, and damp environments. Pumps are self-priming after you fill the pump chamber with liquid. As liquid in the chamber is expelled, a suction force is created which allows the pump to draw liquid upward.

Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry. 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.

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

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 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 four screw cap adapters: 1 3/4", 2 1/8", 2 1/4", and 2 7/8".

Repair kits include components such as extension tubes, gaskets, and pistons.
