In the world of sealing, it seems as though there are as many varieties of pump applications as there are sealing solutions.
Many breakthroughs in technology have aided the evolution from braided packing to advanced mechanical seals, leading to remarkable gains in pump performance, efficiency and safety. Although mechanical seals are certainly a fitting solution for an array of pump and rotary applications, advances in polytetrafluoroethylene (PTFE) rotary lip seals can also solve these challenging radial sealing solutions.
Radial lip seals can retain lubricants and excluded unwanted contaminants for a fraction of the cost of a mechanical seal, while providing many of the same benefits in terms of performance and seal life.
