The design of the ES seal is simple but robust, enabling fast and easy installation and maintenance. The seal is fitted to the standard case cover of the pump. It can be used without flushing, with recirculation flushing or with external flushing.

Sulzer’s ES seal is an optimal solution for water and light process applications. The seal is designed for:

  • clean and slightly contaminated liquids
  • viscous liquids
  • fibrous slurries up to 3% consistency
  • temperatures up to 140°C / 284°F depending on the seal flushing arrangement and seal chamber pressure

The new ES single mechanical element seal is a result of thorough product development. It has been tested in real working conditions to ensure a reliable solution. Sulzer’s worldwide sales and service network will introduce the new seal offering globally, both for new products and for the aftermarket.
