2 GCX Installation
Note: The GCX seal is shipped with the sleeve and gland graphite
gaskets uninstalled. These parts must be assembled onto the seal prior
to installation of the seal into the pump. The gaskets are very fragile;
handle with care.
Note: No seal setting measurements are needed to install the
seal. Instructions are for radially split case end-suction ANSI pumps.
Modification of the procedure may be required for other style pumps.
Consult your Flowserve Representative.
2.1 Tools needed for installation:
• An open end wrench for the gland bolt nuts
• 5/16” open end wrench for the collar bolts
• 3/32” Allen wrench (provided)
• 1/8” Allen wrench (provided)
2.2 Loosen the collar cap screws and remove the drive collar from
the seal assembly.
2.3 Install the sleeve
gasket into the drive
collar. Do not use any
sharp instruments
for installation of the
gasket. Loosely reattach
the collar and gasket
assembly to the seal
with the collar bolts.
See Figure 4.
2.4 Adhere the gland gasket to the gland centered on the register.
Dabs of silicone grease or a spray adhesive may be used to hold
the gasket in place.
2.5 Lubricate the shaft or sleeve lightly with silicone lubricant unless
otherwise specified.
2.6 Tighten the Centering Tab screws.
