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.What's in the Box?THP-ST piston drum pumpSuction tube2" bung adapter

  • good pump. however,
Size: 2" NPT Male
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 ... show more

  • Poor Package
Size: 2" NPT Male
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. ... show more

  • Good sturdy pump
Size: 2" NPT Male
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.

  • Good Quality Stainless Pump
Size: 2" NPT Male
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. ... show more

  • They don't seal very well - Even with lots of Teflon Tape.
Size: 2" NPT Male
I have ordered two of these at different time and both leak. Seals are not great. Even with Lots of Teflon Tape they leak. These are supposed to be Corrosive Safe so not holding a seal isn't great.

  • DO NOT BUY, VERY DANGEROUS DEFECT!!!
Size: 2" NPT Male
For the love of God do not buy this pump! The first time I used it to pump from a 60 gallon drum of Peroxyacetic Acid, a VERY dangerous and aggressive chemical, it failed. Instead of releasing a certain amount of liquid with each pump of the piston, it acted as a siphon creating a stream of liquid that was impossible to stop without removing the entire unit from the drum. I spilled about a gallon of acid and created a mess. I could have been badly hurt or worse! Thank GOD this was outside or my entire building would be shut down right now due to VERY toxic fumes. Amazon was great and issued a refund immediately but that does not diminish how dangerous this could have been. ... show more
