Page 12: Technical Information
6 Technical information 6.1 Technical data Shaft seals Mechanical seals are dependant upon lubrication and cooling of the sealing surfaces. Therefore dry-running of the seal faces must be avoided since this can cause excessive generation of heat and thus possibility of exceeding the specified temperature class. During normal operation a mechanical seal will generate a small but controlled leakage. - Page 13 6 Technical information 2. ATEX compliant single mechanical seal. There is NO monitoring device or protection built into this seal option. It relies on the process fluid to cool and lubricate the seal faces in order to stay within the stated temperature class. The process must be controlled/monitored in a way, which ensures the seal face not to exceed the temperature limit.
