Color:282B-95 | Special Features:3 Phase | Maximum Flow Rate:100 Gallons per Minute | Size:1-1/2" NPT Female Suction & Discharge Ports This AMT self-priming centrifugal pump has a cast iron housing and 1-1/2" female NPT suction and discharge ports. 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 pump housing has buna-n 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 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 pump is suitable for use in applications such as wastewater processing and treatment.

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. American Machine and Tool (AMT) manufactures centrifugal and diaphragm pumps. The company is headquartered in Royersford, PA.
