NOTE
Any leakage must be drained off in a controlled way and safely disposed of.
Components which may come into contact with the seal leakage must either be
corrosion resistant or must be adequately protected.
WARNING
Incorrect handling of the fluid to be sealed off
Risk of injury!
▷
If the fluid to be sealed off and/or the buffer fluid have to meet the
requirements of the German Hazardous Substances Regulations, the regulations
on handling hazardous substances (safety data sheets to Directive 91/155/EEC)
and the accident prevention regulations must be heeded.
6.3 Operating limits
NOTE
Always observe the operating limits in the product literature and the other
applicable documents.
NOTE
The following values are limits that depend on the seal face materials and
elastomer materials. As the characteristics influence each other, operation at
minimum/maximum limits is not possible for all characteristics at the same time.
