Description
The CPM PP seal is a cartridge mounted mechanical seal, designed for
ease of installation and reliable operation. No seal setting dimensions
are required. Rotatable setting devices provide proper alignment. The
flexible stator design compensates for inadvertent misalignment of the
seal chamber face. Multiple springs provide uniform face loading and
are external of the pumpage, resisting clogging or hang-up. Installation
according to the following steps will assure long trouble free life of the
CPM PP seal.
