Single cartridge mounted welded
metal bellows seal
Installation
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.

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.
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-100 seal with care, it is manufactured to precise
tolerances. The sealing faces of rotating and stationary faces 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.
2 X-100 Seal Installation
Tools needed:
• Open end wrench for
gland nuts
• Allen wrenches provided
• Silicone lubricant provided
2.1 Lubricate the shaft or sleeve
OD lightly with silicone lubricant
provided and slide the complete
X-100 Cartridge seal onto the shaft, Figure 3, with the end with
the setting devices toward the bearing housing.
2.2 Install the pump backplate (seal chamber), Figure 4. Position the
X-100 seal gland ush connection, port a in Figure 7, in the
3:00 o’clock position for normal installations. Alternate positioning

of the gland may be necessary with
some pump designs to permit seal
piping to clear the bearing housing.
Refer to the assembly drawing
that is supplied with the seal for
proper positioning. Bolt the back
plate in place on the bearing
housing.
2.3 Assemble the pump, adjust the
bearings, set the impeller and
connect the coupling so
that the shaft is in its operating
axial position. Any subsequent
adjustment of the shaft requires
resetting of the seal. Connect
pump piping, allow no pipe strain
on the pump casing.
2.4 Position the X-100 cartridge gland
with the gland gasket in place against
the seal chamber (stufng box) face
and tighten the nuts evenly, cross
staggering the adjustment of the nuts.
The gland nuts should be torqued to
a maximum of 13 N-m (10 ft-lbs).
Excessive gland nut pressure can
result in distortion of the stationary face.

2.5 Tighten the set screws on the X-100
cartridge drive collar with the Allen
wrench provided. See Figure 5.
2.6 Remove setting devices by removing
the cap screws with the Allen wrench
provided. See Figure 6. Save the setting
devices for use if pump impeller must be
reset or if the X-100 is removed for
maintenance.
2.7 Turn the shaft by hand to ensure free
operation.
2.8 Pipe up the gland connections to the
X-100 seal, see section 3.
2.9 See Operational Recommendations,
section 4, before starting pump.

Consult your Flowserve Sales and Service Representative or Flowserve
Authorized Distributor for assistance in selection of seal environmental
control plans. Usually one of three ush plans is used:
3.1 ASME Flush Plan 7302, dead-ended, may provide adequate
removal of seal generated heat if the pump is equipped with an
enlarged seal chamber or if the shaft speed and chamber pressure
is low. If no ush is used, plug ush port a , Figure 7.
To maximize seal life, Flowserve recommends that a product bypass
or clean external ush be used whenever possible with a X-100 seal
installed in a conventional seal chamber such as a converted stufng
box.
3.2 ASME Flush Plan 7311, product bypass ush, is piped from the
pump discharge to the X-100 seal ush port a , Figure 7. It may
be necessary to install an orice in the bypass line to reduce the
ush velocity. The bypass may be cleaned or cooled as necessary.
A Flowserve Floating Throat Bushing installed in the bottom of the
seal chamber can be used to pressurize the chamber for products
near their boiling points.
3.3 ASME Flush Plan 7332, clean external ush, is a supply of clean
compatible ush uid at a pressure at least 170 kPa (25 psi) above
that in the seal chamber piped to the X-100 seal ush port a ,
Figure 7, at a ow adequate to remove seal generated heat. A
Flowserve Floating Throat Bushing or other device installed in
the bottom of the seal chamber can reduce product dilution to a
minimum.
3.4 Taps b and c in the gland are vent and drain ports used for
uid quenching, ASME Flush Plan 7362. If they are not used, they
should be plugged with pipe plugs.

4 Operation
Following these recommendations will ensure maximum MTBPM
of the X-100 seal.
4.1 The X-100 is designed to resist corrosion by most chemicals. However,
do not expose the X-100 materials of construction to products outside
of their corrosion limits. The X-100 assembly drawing lists the materi-
als of construction. Contact Flowserve for chemical resistance ratings.
4.2 To request Pressure-Velocity (P-V) limits contact Flowserve.
4.3 The materials of construction are listed on the assembly drawing
supplied with the X-100 seal. Contact Flowserve for the temperature
limits of materials.
4.4 Do not start up or run the X-100 dry. Product or ush uid must be
in the seal cavity at all times during pump operation.
For any special problems encountered during installation, contact your
nearest Flowserve Sales and Service Representative or Authorized
Distributor.
5 Repair
5.1 To reset the pump impeller, follow plant safety procedures, see 1.1.
• reinstall the X-100 setting devices using the cap screws.
• loosen the X-100 cartridge drive collar set screws.
• adjust the impeller clearance following pump manufacturers
instructions.
• tighten the set screws on the X-100 cartridge drive collar.
• remove the setting devices by removing the cap screws.
This product is a precision sealing device. The design and dimension
tolerances are critical to seal performance. Only parts supplied by
Flowserve should be used to repair a seal. These are available from
numerous Flowserve stocking locations. To order replacement parts,
refer to the part code number and B/M number. A spare backup seal
should be stocked to reduce repair time.
When repairs are not conducted at the customer's location, decontami-
nate the seal assembly and return it to Flowserve, with an order marked
"Repair or Replace". A signed certicate of decontamination must be
attached. A Material Safety Data Sheet (MSDS) must be enclosed for
any product that came in contact with the seal. The seal assembly will be
inspected and, if repairable, it will be rebuilt, tested, and returned.
