Seal Reliability Case Studies
Selecting the ideal seal technology for each application provided vast improvements in reliability, housekeeping (product leakage onto the floor and other equipment), safety, product waste, asset uptime. In each case study that will be discussed, costs were reduced; MTBF was increased, and money was saved because product loss was minimized or eliminated. The case examples that will be discussed are: • Air seal for a potato chip seasoning conveyor: Product loss was completely eliminated. • Mechanical seal system in ethanol plant: Meantime between repair increased from one year to three. • Bearing isolator in a paper plate manufacturer: Success with one gearbox eliminated lubricant leakage and downtime for bearing isolator and felt roll replacement. • Pump air seal system in paper mill: MTBF of a hydrapulper discharge pump increased from about two weeks to 18 months and counting.
