Specifications
PumpPiston drum pump, hand-operatedMaterialsStainless steelFlow rate22 oz. per strokeSuction port1.5"For use with15, 30 or 55 gallon drumsDimensionsOverall length: 41"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.

This works really well, the hose that is supplied may not be fuel or oil compatible but still worked.

We purchased this hand pump 07/2022 for our bulk brake cleaner and it has been working flawlessly since then. This is the first pump for brake cleaner I have worked with in over 30 years that hasn't failed in one way or another in a short amount of time. It also came with spare gaskets, so I am sure we will be using it for years to come.

Received product with 2 missing parts, I guess it got lost on the way, because the box was broken. Since we needed it urgently, we replaced (1 part) the black botton, the other part missing was the tension spring, we are using it without it. Other than that, it is working fine. Although, we have used it only for one week now.

its a pretty decent pump, used it to pump acetone out of a 55 gallon drum at work. good strong stream once it starts going. but it start to not keep a tight seal when dealing with acetone. started leaking out the top near the pull handle. about early ~ November I bought it February 2021, had to switch it out at the beginning of December 2021. the leaking out the top was getting bad. to much waste for the price of acetone today was used multiple times a day by different people in a shop environment

Great pump. Seems well made and heavy duty. We use it to pump an aggressive degreaser and it’s holding up well. More expensive that the plastic version of these pumps but seems like it will last longer and not leak at the shaft packing like the plastic ones alway start to do quickly.

So far so good, we use these for 55 gallon drums of mold release and roll coat cleaner (some pretty aggressive chemicals) in our manufacturing plant. Almost 2 months and still going strong. Previous pumps had rusted and broken in half within a couple of weeks but this is the best one we have have so far. We have these in our manufacturing plant in a place where the pumps are being used upwards of 20 times a day.

Purchased this item for transferring solvent into a dry cleaning machine. The PTFE gaskets provided with this item were an important factor in considering the purchase of this particular item. The pump works perfectly! Absolutely no leaks and is very easy to use. The pump transfers on both the push and pull of the knob, making the transfer of solvent very easy and quick.
