This Action Pump 7007 hand-operated piston siphon pump is made of PVC (polyvinyl chloride) for resistance to acids and alkalis, delivers 8 oz. of fluid per stroke, and is suitable for dispensing detergents, most acids, chlorines, oils, D-limonene, waxes, alkalis, water, or soaps. It has a 1-1/2" inlet port and a 1" outlet port with a 5" polyethylene discharge tube that resists abrasion and corrosion. This pump can deliver a maximum of 7 gallons of liquid per minute (gpm) (3 gpm for oil) with a maximum viscosity of 650 centipoise (cps). It comes with a 2" National Pipe Taper (NPT) threaded bung adapter, and a flow control mechanism to regulate siphoning. This siphon drum pump is suitable for use with 15, 30, and 55 gallon drums for dispensing liquids in a wide range of industrial and commercial applications.SpecificationsPumpPiston siphon pumpMaterialsPVC pump and components, polyethylene suction and discharge tubesFlow rate8 oz. per stroke (7 gpm maximum; 3 gpm for oil)Suction port1-1/2"Discharge port1"Maximum temperature140 degrees FMaximum liquid viscosity650 cpsFor use with15, 30, and 55 gallon drumsWeight4 lb.DimensionsOverall length: 42"; Discharge hose: 5"; Suction hose: 40" 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.
