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.

Arrived decently packed in an unassuming brown box.....not factory packaged. It's very well made and lighter than I expected. I plan on mounting this near my sump pump in the even we loose power and need to empty the sump in an emergency. I do have a generator, but having a manual way to empty water is always a good idea.

Pros: Construction wise it's tough and will probably last for ever. No issues with fit or finish. All parts are quality and no rattling around anywhere. I can mount this to a wall, bench top or easily move it around due to it's light weight. Any one can use it.

Cons: Both inlet and outlet are smooth bored. Attaching hoses are easy but could "slip" off since braces have nothing to grip. Not that it's a deal breaker but it didn't come with instructions. I can figure it out but I like the assurance of having some if I need it. I don't know if the manufacture has original packaging, but it looks like it was re-packed. Still, item arrived in 'new' condition with no signs of any previous use.

UPDATE: 7/13/14. Well I finally got to use it in a real world situation. I decided changed my hoses and test the new connections out to check for leaks since there is no way to insert gaskets (smooth inlets). While empting a few 5 gallon test buckets filled with water, the flow rate of 900gph as advertised is excessively high. It took me 5 minutes to get it primed manually then another 3-4 minutes to empty one bucket. I'm using an industry sump hose inlet down to a 1" stepped down brass end on the other. Typical garden hose connection.
Why did it take me so long to test it ? I just noticed that I had punctured one of my hoses. Better late than never I guess.
All in all it works great but don't expect to flush out a basement in under 30 minutes expecting to achieve their flow rate. Empting 55 gallon buckets or a sump will be just fine.....if you don't mind waiting a little while.
