This AMT self-priming centrifugal utility pump has 3/4" or 1" female NPT suction and discharge ports. The pump is self-priming (after initial fill), and the priming lift ranges from 6 to 15 feet, depending on the model. The pump housing is either aluminum with Viton (FKM, fluoroelastomer) seals or bronze with buna-n seals, depending on the model. The motor enclosure is either totally enclosed, not ventilated (TENV) for protection from dust or open, drip proof (ODP) for protection from dripping water, depending on the model. This portable pump is suitable for use in liquid transfer or recirculation applications.

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.
