This AMT 388F-97 bronze inline centrifugal pump has a 1/2 hp, 115/230V, 1 phase electric motor and 1-1/2" female NPT suction and discharge ports. This pump has A curve performance with a 50 gallons per minute (gpm) maximum flow rate and 48 feet maximum vertical lift at 3,450 RPM. The pump housing has a pull-from-rear design for servicing without disturbing pump housing connections, a stainless steel self-cleaning impeller that handles semi-solids up to 1/8" diameter, 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 portable pump requires flooded suction for priming and is suitable for use in applications such as liquid transfer, recirculation, and wash down.

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.
