Instructions
Congratulations
You have just purchased a reliable, long-life product manufactured by
the leading manufacturer of sealing systems in the world. With proper
installation and operation, this X-200 seal can be a valuable contributor
to your operation by signicantly reducing the mean time between
planned maintenance (MTBPM) of your rotary equipment.
Description
This X-200 seal is a cartridge mounted end face welded metal bellows
mechanical seal, designed for ease of installation. No seal setting
dimensions are required. Removable setting devices provide proper
alignment. The welded metal bellows eliminates shaft fretting and resists
clogging or hang-up. Installation according to the following steps will
assure long trouble free life of the X-200 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.

1.2 Disassemble equipment in accordance with equipment
manufacturer’s instructions to allow access to seal installation area.
1.3 Remove existing mechanical seal and gland or compression
packing and packing gland (follower ange).
1.4 Make sure the shaft or sleeve is free of burrs, cuts, dents,
or corrosion that might cause leakage past the sleeve gasket,
as shown on the assembly drawing. Replace worn shaft or
sleeve. Remove sharp edges from keyways and threads.
1.5 Make sure the seal housing face is clean and free of burrs, cuts,
dents, or corrosion that might cause leakage the gland gasket or
misalign the seal gland.
1.6 Check equipment dimensions to ensure that they are within
the dimensions shown in Figures 1 and 2. Critical dimensions
include shaft or sleeve OD (A), a chamber depth (C), minimum
and maximum seal housing bore (B), and the minimum distance
to the rst obstruction, (E) plus 0.125 inch.
1.7 Check gland bolting to ensure that bolt diameter (G) and bolt
circle (H) conform to the dimensions shown in Figure 2.
1.8 Handle the X-200 seal with care, it is manufactured to precise
tolerances. The sealing faces of the rotating face and stationary
face are of special importance. They are lapped at to within
three light bands (34.8 millionths of an inch). Keep the seal
faces perfectly clean at all times.
