Meeting Today's Process Requirements With Yesterday's Investment

Chances are that your Rosenmund filter that has provided your company with years of service is still in extensive production, years after the initial capital investment was made. In fact, the first automatic scroll discharge filter built by Rosenmund in 1966, is still in operation today!

You’ve purchased a quality piece of equipment and conducted proper maintenance and repairs. Your Rosenmund machine can be upgraded and modernized to provide additional years of useful service. Now is the time to consider upgrading to one of the many design options offered inside this this information bulletin.

All of the upgrades listed can be expertly and efficiently implemented at your plant site: the machine stays in-place at your location.

Case History
In December 2002, two (2) 1991 4.0m2 Rosenmund Filters were upgraded with double mechanical seals and bellows that replaced the original main shaft stuffing box.
The customer required that the process conform to more stringent guidelines that mandated the elimination of packing particulate and fugitive emissions.
All up-grade components were ordered in advance while the machines stayed in operation. During a scheduled shutdown, modifications were completed on-site within a two week window for both filters.
