Use less electricity to achieve the same flow rates as other circulation pumps. These pumps have a totally enclosed motor for use in dusty, dirty, and damp environments. Adjust the housing studs to make the discharge direction more vertical or horizontal. Pumps are gravity fed and require an elevated liquid source to fully fill the pump before turning on. 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.

Pumps that cannot be sold to the listed regions do not meet energy efficiency requirements.

A powerful motor provides twice the flow rate of other self-priming circulation pumps. It is totally enclosed fan-cooled (TEFC) for use in dusty, dirty, and damp environments. Install these pumps up to 20 ft. above your liquid source to drain underground tanks and process wastewater. They 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.

Pumps that cannot be sold to California do not meet energy efficiency requirements.

With a sanitary design and electric motor that is quieter and uses up to 80% less energy than air-powered transfer pumps, these pumps move liquids in food-, dairy-, and cosmetics-processing plants. To prevent bacteria growth, as well as make them easier to clean thoroughly, they have polished surfaces. Their housing is 316 stainless steel to withstand harsh cleaners and sanitizers, such as those used in clean-in-place (CIP) cycles. Add them to your line by using gaskets and clamps to connect them to sanitary quick-clamp fittings (often called tri-clamp fittings); they’re easy to assemble and remove for cleaning. All are FDA compliant for direct contact with food.

Used to transfer lotions, yogurts, creams, sauces, and beverage concentrates from one container to another, these diaphragm pumps work well for thick liquids that contain solids. They can run dry without damaging themselves and are self-priming, meaning they create suction that draws liquid up to fill the pump chamber.

To use them with flow and batch-control meters, set these pumps to low pulsation mode. This mode makes their flow more consistent than the pulses and bursts that are typical for diaphragm pumps.

Pumps with a PTFE diaphragm stand up to hot oils and chemicals. They work with organic oils, such as those used in salad dressings and marinades.

Pumps with a Santoprene or EPDM diaphragm have better suction and last longer than pumps with a PTFE diaphragm because they’re more elastic. They’re good for moving body scrubs, chocolate, liquid sugar, and other liquids that contain abrasives. However, they’re not for use with organic oils and animal fats. 3-A certified, they meet a standard for sanitary design.
