Revolutionary New Seals Built to Last in Abrasive Environment

When Randy Webb called one of his chemical plant customers in northern Ohio recently, the JNO. J. Disch Company sales engineer thought he might have a new solution to a nagging problem at the facility. Over the past five years, the plant had been seeking an alternative to the double titanium mechanical seals used on a series of ANSI pumps. The mechanical seals had limited durability in the corrosive environment of the plant. In most cases, the seals lasted a mere 4 weeks at a time...6 weeks at most. The piping system was used to pump brine solution throughout the plant. It is easy to understand why the hostile environment was so hard on equipment and seals. In addition, the titanium seals were expensive, costing $1,500- $1,800 to replace and requiring a shut-down of plant equipment during repairs. This pump system in the plant production line contained 11 pumps which could easily mean as much as $215,000 or more in mechanical seal repairs for one line during a given year; plus lost production time.
