This AMT industrial coolant pump has a cast iron casing, column, and base and includes a universal mounting bracket. Discharge ports range in size from 3/4" to 1-1/2", depending on the model. The cast iron casing, column, and base provide strength and the stainless steel impeller, shaft, and fasteners resist scaling and corrosion. The self-cleaning, semi-open impeller is more efficient than an open impeller and is less likely to clog than a closed impeller. This pump requires no mechanical seal where back vanes on the impeller balance the pressure. A double volute chamber increases efficiency at operating speeds by reducing the radial forces on the impeller. This pump handles liquids with viscosities up to 500 Saybolt Seconds Universal (SSU), such as sesame oil at 60 degrees F. The totally enclosed, fan cooled (TEFC) electric motor is protected against dust and indirect water spray but is not submersible -- the mounting bracket system controls immersion depth. The motor enclosure complies with National Electrical Manufacturers Association (NEMA) 56J standard for mounting dimensions and this unit includes a universal mounting bracket. This industrial coolant pump is for use with nonflammable liquids in applications such as evaporating coolers, fountains, and laboratories.SpecificationsMotor1/8 to 3/4 hp, TEFC, 1725 RPMPumpCentrifugal with double voluteMaximum flow rateRanges from 15 to 67 GPMImpellerStainless steel, self-cleaning, semi-openDischarge port1-1/2" NPT femaleMaximum immersion depth6.3"/160.0 mm to 12.2"/309.8 mmMaximum liquid operating temperature200 degrees FMaximum liquid viscosity500 SSUStandards metNEMA 56JPumps 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.
