Instructions
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 exible 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
1.1 Follow 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 les for hazardous material regulations.
