This AMT 282B-98 stainless steel self-priming centrifugal pump has a 2 hp, 3 phase, 230/460V TEFC electric motor and 1-1/2" female NPT suction and discharge ports. This pump has C curve performance with a 100 gallons per minute (gpm) maximum flow rate and 97 feet maximum vertical lift at 3,450 RPM. The pump is self-priming to 20 vertical feet (after initial fill) with its built-in check valve, and its clog-resistant impeller handles semi-solids up to 3/8" diameter. The 300 series cast stainless steel pump housing has Viton (FKM, fluoroelastomer) mechanical seal and O-ring, a fill and drain plug for easy servicing, and a double volute chamber for reduced radial load on the impeller. 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 is suitable for use in applications such as waste water drainage and processing.

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.
