The AMT Pump 4020-95 industrial/commercial sump pump is powered by a 1/2 HP, 115 VAC, 60 Hz, single-phase TEFC electric motor, constructed with a cast iron body and impeller, 300 series stainless steel shaft and float, and carbon bearings, and is suitable for a wide range of clean water drainage applications with up to 3/4" solids. It is capable of transferring up to 103 gallons of fluid per minute (gpm) with zero total head and has a 20' total head rating. It is equipped with a float assembly for automatic shutoff, a semi-open clog-resistant impeller, 8' of 16/3 115 VAC line cord, and a 2" female National Pipe Thread Taper (NPT) discharge port for compatibility with most discharge hose assemblies. It is 39.9" tall and requires a sump pit at least 14" in diameter and 24" deep for operation. This pump can transfer material ranging from 40 to 200 degrees F (4 to 93 degrees C), and it ships fully assembled except for the float assembly. This pump is suitable for clean drainage applications in residential, commercial, and industrial settings where solids do not exceed 3/4".

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.
