Durametallic® X-100
Single cartridge mounted welded metal bellows seal
Experience In Motion
Description
This X-100 seal is a cartridge mounted mechanical seal, designed for ease of installation and reliable operation. No seal setting dimensions are required. Removable setting devices provide proper alignment.
The flexible stationary face 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 X-100 seal.
1 Equipment Check
1.1Follow plant safety regulations prior to equipment disassembly:
•Lock out motor and valves.
•Wear designated personal safety equipment.
•Relieve any pressure in the system.
•Consult plant MSDS files for hazardous material regulations.
