Mechanical lip seal

March 30, 2003

The Mechanical Lip Seal (MLS), designed for pumps in high-viscosity applications, combines the versatility of mechanical packing and the advanced performance of a mechanical seal. Three interchangeable PTFE sealing elements can be replaced or repaired on-site, extend- ing the longevity of the seal, shortening downtime and simplifying maintenance. The MLS has a 316 stainless-steel gland and sleeve, and the three modular PTFE sealing elements which sequentially control system pressure. The seal can also be configured for vacuum services, using a pressure transducer for system monitoring, or for abrasive services, using an internal packing ring.

The lingering effects of the pandemic on food processors were felt throughout 2021, with labor issues, increased automation, ingredient shortages, the need for additional energy efficiencies and technologies to help streamline operations, and more, all having an impact.

Food and beverage companies consistently develop new products, but current speed-to-market expectations have made efficiency a crucial factor in putting those new products into the hands of customers ahead of the competition.
