This AMT 316A-95 engine-driven sewage and trash pump has a cast iron housing, a 3 hp, 3 phase, 230/460V TEFC electric motor, and 2″ female NPT suction and discharge ports. This pump has A curve performance with a 150 gallons per minute (gpm) maximum flow rate and 62 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 fluids containing up to 15 percent semi-solids. The pump housing has Viton (FKM, fluoroelastomer)/silicon carbide mechanical seals and Viton O-rings for corrosion resistance. The housing’s double volute chamber reduces radial load on the impeller, and both the volute and impeller are replaceable with the removal of four bolts. The motor enclosure is totally enclosed, fan cooled (TEFC) 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 in sewage treatment, canneries, chemical processing, wineries, tanneries, meat packing, breweries, pulp, wood chips, sludge and slime, and waste water.

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