This Action Pump FM-81 hand-operated rotary drum pump has a cast iron body and aluminum nozzle, delivers 6 gallons of fluid per minute (gpm), and is suitable for dispensing flammable liquids. The pump has a cast iron body has strength and durability and an aluminum nozzle for lighter weight and corrosion resistance. The pump is Factory Mutual Research Corporation (FM) approved for safety, and comes with a neoprene dispensing hose, a 2" bung adapter, a 41" suction tube, and an attachment for hanging up the dispensing nozzle. This rotary drum pump is suitable for use with 15, 30, and 55 gallon drums in a range of industrial and commercial applications.SpecificationsPumpRotary drum pump, hand-operatedMaterialsCast iron, steel, graphite, polypropylene, zinc plated steel, neopreneFlow rate6 gpm maximumDischarge spout1"Maximum viscosity350 cpsMaximum temperature140 degrees FFor use with15, 30 or 55 gallon drumsWeight10 lb.DimensionsOverall length: 51-1/2"; Suction tube: 41"Standards metFM approved 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.Action Pump manufactures drum and pail pumps and grease, oil, and lubrication products. The company, founded in 1981, is headquartered in Cary, IL.What"s in the Box?FM-81 rotary drum pumpCurved spout41" suction tube2" bung adapterDispensing hose with nozzleHang-up attachment
