AMT Pump 4782-95 Two Stage High Pressure Pump, Cast Iron, 3 HP, 1 Phase, 115/230V, Curve G, 1-1/2″ NPT Female Suction & Discharge Ports

This AMT 4782-95 two-stage high pressure sprinkler and booster pump has a cast iron housing, a 3 hp, 1 phase, 115/230V ODP electric motor, and 1-1/2″ female NPT suction and discharge ports. This pump has G curve performance with a 57 gallons per minute (gpm) maximum flow rate and 180 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. The pump housing has a stainless steel high-efficiency closed impeller and buna-n mechanical seals and O-rings. The motor enclosure is open, drip proof (ODP) for protection from dripping water. This portable pump is suitable for use in applications such as in pressure-boosting transfer and sprinkler 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.

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