Like people, most liquid ring vacuum pumps retire after 30 or 40 years.They get tired or their skills become surpassed by the younger generation.However, we”ve found one instance of a liquid ring vacuum pump that worked for 82 years before being removed for repair!The pump in questions, a NASH Hytor #6 pump, worked on the pulp dryer machine, on a top felt Uhle box, at Simpson Tacoma Kraft Company. The plant was built in 1928 by the Union Bag Company, and the #6 was there from the start. During its 82 years, the #6 pump has seen the company change hands a number of times, but it kept on doing its job.Retirement comes eventually of course, and the NASH #6 pump has gracefullygiven way to a NASH Vectra XL. The former could have kept on working withbearings replacement, but the thought now was the best time to put the old pump to bed in favor of a newer model. Do you have an old Nash pump still running?Nash is running a contest to see what other pumps have been working hardfor many years. The person who submits the oldest pump will WIN A GPSNAVIGATOR! Your pump doesn’t have to be 82 years old like the one shown; it just has to be older than the other contest entries. For contest details, go to www.GDNash.com/oldestpump.aspx. Entry forms will be accepted until November 1, 2010.
