Devices with PTFE-coated diaphragm seal process membrane
The anti-stick coating has very good anti-friction properties and protects the process
membrane against abrasive media.
NOTICE
Destruction of the device due to incorrect use of PTFE coating!
‣
The PTFE coating used is designed to protect the unit against abrasion. It does not
provide protection against corrosive media.
