This AMT straight centrifugal pump has a cast iron housing, 2" female NPT suction ports, and 1-1/2" NPT discharge ports. The pump housing has a self-cleaning impeller that handles semi-solids up to 1/8" diameter, a fill and drain plug for easy servicing, a discharge port that rotates at 90-degree increments for flexible installation, and buna-n mechanical seal and O-ring. The motor enclosure is TEFC (totally enclosed, fan cooled) for protection from dust and indirect water spray and complies with National Electrical Manufacturers Association (NEMA) 56J standard for mounting dimensions. This pump requires flooded suction for priming and is suitable for use in applications such as liquid transfer and 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.
