Model ZLR-1100 - Single Cartridge Mechanical Seal Datasheet

Cartridge Design – No measuring, self centering installation.  Just slide over shaft, tighten gland bolts and set screws, remove centering clips, and the seal is ready to operate. Double Balance – World’s first double balanced single seal.  O-ring shifts to accommodate pressure from either the process side or the atmospheric side when the pump is under vacuum.  Wide o-ring groove absorbs o-ring swell without hanging up seal.
