The AMT Pump 5811-99 submersible utility pump is a UL- and CSA-listed centrifugal pump constructed with a plastic housing and impeller for light weight and portability and a Buna-N seal for resistance to oils and solvents, and is suitable for a wide variety of clear water drainage applications. It is equipped with double mechanical seals with carbon and ceramic wear faces for protection of internal components, and measures 12.6 x 6.2 x 9.4 inches (H x W x D). (H is height, the vertical distance from bottom to top; W is width, the horizontal distance from one narrow side to the other; D is depth, the horizontal distance from the front of the discharge port to the back of the unit.) It is capable of transferring up to 48 gallons of fluid per minute (gpm) with zero total head at temperatures ranging from 40 to 104 degrees F (4 to 40 degrees C), and has a 21' maximum total head rating. This pump comes equipped with a 1/2 horsepower (HP), single-phase, 115 VAC motor with automatic restart thermal overload protection, rated for continuous duty at 3450 revolutions per minute (rpm) and fitted with a 13' three-prong Underwriters Laboratories (UL)-approved, Stranded Junior Service Thermoplastic Weather-Resistant Compound (SJTW) power cord. It ships fully assembled and features a carrying handle, a mercury-free float switch, and a 1-1/2" female National Pipe Thread Taper (NPT) discharge port with an optional 1-1/2" male hose barb adapter for compatibility with most discharge hose assemblies. This pump is suitable for a wide range of residential, industrial, and commercial applications including sump pits, drainage pits, overflow tanks, basements, dewatering, excavation, grain elevators, construction drainage, cooling towers and other applications requiring clear water removal.
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.
