This AMT stainless steel straight centrifugal pump has a high-efficiency closed impeller and Viton (FKM, fluoroelastomer) mechanical seal and O-ring for resistance to corrosion and chemicals. The motor enclosure is either TEFC (totally enclosed, fan cooled) for protection from dust and indirect water spray or ODP (open, drip proof) for protection from dripping water, depending on the model, and complies with National Electrical Manufacturers Association (NEMA) 56J standard for mounting dimensions. This corrosion resistant pump requires flooded suction for priming and is suitable for continuous duty use in applications such as high volume transfer and recirculation.

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.

I utilize three of these in different applications to pump water and they hold up incredibly well. They're easy to work on if you ever need to change out seals and are very reliable

I purchased 2 of these because they sell them as 35 - 155gpm and 150psig. These pumps barely provide 10gpm at 2 psig. Both of the ones I purchased have flooded suction with no back pressure and the maximum flow I can get with no back pressure is 12gpm and with 20psig I get around 2gpm.

This pump met my requirements in terms of flow rate. As tested, it delivered over 90 gpm which is good for my application.

This pump worked great....that is, until it quit working less than 2 months after purchase. Ironically enough, Amazon says that it is out of its return period now. Great....thanks.
