In the diverse applications for calenders and similar units in many areas of the above mentioned industries it is extremely important to provide optimum sealing arrangements for the rotary bushings used.

The Problem
Be it for heating or cooling, with hot oil or coolant - when media with extreme temperatures are pumped through a hollow shaft, DEPAC's great experience with matching mechanical seals really pays.

The DEPAC Solution
Elastomer materials could not be used on account of the high temperatures of approx. 280 °C (536 °F) to 300 °C (572°F). DEPAC recommended a HASTELLOY C rolled bellows.

The special seal was configured as a stationary design in order to guarantee optimum operational safety and reliability.
