Tramco Pump Co.'s Vertical Column Pump offers several benefits to the user. Its direct interchangeability means no additional piping or installation costs are needed. Its oil-lubricated design means all sleeve bearings are continuously being lubricated in clean oil. It features a mechanical seal that keeps the oil-filled column free from contaminants. And its hot-dipped galvanized piping, including a Schedule 80 steel column and Schedule 40 discharge column, offer longer pump life.Tramco Pump Co.
