Universal
cartridge mechanical seal for technically demanding applications - high
degree of capacity for solids.
Assembly aids fix mechanical seal in position ready for installation.
Complete mechanical seal with sleeve and cover with circulation connections
(quench optional).
Exclusive use of solid seal face/ stationary seat - self-aligning arrangement
in stationary design ensures safety of operation and usually increases
service life.
Mechanical seal is also very suitable with retrofitting of packing;
usually fits into packing stuffing box compartments.
Mostly required materials/ mating of materials available; s. material
