This AMT stainless steel straight centrifugal pump has a high-efficiency closed impeller and Viton (FKM, fluoroelastomer) mechanical seal and O-ring for resistance to corrosion and chemicals. The motor enclosure is either TEFC (totally enclosed, fan cooled) for protection from dust and indirect water spray or ODP (open, drip proof) for protection from dripping water, depending on the model, and complies with National Electrical Manufacturers Association (NEMA) 56J standard for mounting dimensions. This corrosion resistant pump requires flooded suction for priming and is suitable for continuous duty use in applications such as high volume transfer and recirculation.

Pumps use mechanical action to move liquids, gases, or slurries (solids suspended in a liquid or gas). The mechanical action is categorized as either positive displacement (PD) or kinetic. PD pumps capture and release discrete amounts of flow into a chamber and then force it out. Some examples of PD pumps are fuel and oil pumps in cars, pumps in hydraulic systems, and bicycle pumps. Kinetic pumps move liquids, gases, or slurries by transferring energy from the pump's movement to the flow. They use an impeller to draw the flow in, add energy to the flow, and move it through a volute (a spiral funnel through which the flow moves), and into the system. Some examples of kinetic pumps include centrifugal (the most common pump in industrial applications), in-line pumps, sump pumps, and suction pumps. Energy sources for all types of pumps include wind power, manual operation, electricity, and gasoline or diesel fuel.
