Technical advantages
The beliows and spring are free from torsional stress.for a long service life (positive application of force to the seal face via the L-ring)
No adhesive-bonded connections
Compact,one-part bellows unil with a fixed seal face for reliable operation (no deposits can collect between the bellows and seal face,so misalignment is not possible)
Precise centering between the cover and seal urit achieved by to use of four mounting fixtures Large clesrance between the cover,stuffing box chamber and seal to assist self-cleaning and cooling of the stuffing box chamber
Very thick flange for highly rigid cover to protect against misalign-ment (bowing) when the cover is bolted onto the pump housing,thereby avoiding gasket teaks. |
