Color:3792-95  |  Special Features:1 Phase  |  Maximum Flow Rate:78 Gallons per Minute  |  Size:1-1/2" NPT Female Suction & Discharge Ports This AMT self-priming sprinkler and booster pump has a cast iron housing and 1-1/2 or 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 has a stainless steel high-efficiency closed impeller. The pump housing has buna-n mechanical seals and O-rings, its double volute chamber reduces radial load on the impeller, and both the volute and impeller are replaceable. The motor enclosure is either totally enclosed, fan cooled (TEFC) for protection from dust and indirect water spray or open, drip proof (ODP) for protection from dripping water, depending on the model. This portable pump is suitable for use in applications such as in pressure-boosting transfer and sprinkler applications.SpecificationsMotor1.5 to 7.5 hp, ODP or TEFCPumpCentrifugal self-priming with dual voluteMaximum flow rateRanges from 80 to 157 gpmImpellerStainless steel, high efficiency, closedSuction port1-1/2" or 2" NPTDischarge port1-1/2" or 2" NPTMaximum operating temperature180 degrees FMaximum solids handlingRanges from 1/16" to 5/16"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.

Highly recommend. We had been running a old cast iron ...
Can't believe what a difference this pump made in our irrigation. Using 1 1/4" direct pull from a shallow well, reduced to 1" out, i have several 200 foot run zones with 8 to 9 Rainbird 5000 series heads. It pushes the full distance. Highly recommend. We had been running a old cast iron 1.5 that was probably 15 years old.

Shoddy workmanship and cheap thin gasket.
After we installed the new pump we found a leak. We broke down the pump and discovered that the rubber gasket had not been properly installed and was pinched down in one location not properly seated in the right place. The gasket was damaged and not useable. We had to replace the gasket ourselves. We happened to have the old one from the one we were replacing and took the gasket out of it to use in the new one. The old gasket was twice as thick as the new one. Very shoddy workmanship and it looks like they are trying to save money using a cheaper gasket.
