الوصف

Color:577E-95  |  Special Features:3 Phase  |  Maximum Flow Rate:450 Gallons per Minute  |  Size:4" The AMT cast iron submersible contractor pump is UL- and CSA-listed, constructed with a cast iron body, a stainless steel motor housing, a high chromium (HCr) steel impeller and cover for wear resistance and durability, silicon carbide seals for resistance to abrasion and corrosion, and is suitable for liquid drainage applications with solids up to 3/8" diameter. Its electric motor is rated for continuous duty at 3450 revolutions per minute (rpm), and it can convey material ranging in temperature from 40 to 104 degrees F. It ships fully assembled and features a suction screen, carrying handle, 32' of unfinished power cord, and a female National Pipe Thread Taper (NPT) discharge port for compatibility with most discharge hose assemblies. This pump is suitable for liquid drainage applications in residential, commercial, and industrial settings, including construction sites, waste water, irrigation, excavation, mining, marine, and other general drainage applications where solids do not exceed 3/8" in diameter.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.
