description: "Our two favorites vacuum pumps are made by either Travaini or Dekker. Both are liquid ring vacuum pumps and are known to last over 50,000 hours. We once saw a liquid ring still in service with 84,000+ hours on it. With that said this 2002 Travaini DynaSeal TRO 500S-1A has 14,325 hours, is powered by a 40 hp motor, and capable of Nominal Capacity (ACFM) @ 20″ HgV: 500. Please Note: YES, the paint is original! This fully functional machine has been fully cleaned, checked, and is ready to work from the time you receive it. This is our guarantee to both you and your company. It is owned by 360 Degree Machinery and located in our inventory in Kingston, TN."
