where leakage from the packing is stopped.
Component seals that do not required
setting:
Tighten the gland nuts [6580.8]
h) Components seals that required setting:
The following steps are only necessary for these
types of seals.
•
Put bluing on the shaft and mark the shaft at
the face of the gland [4120.3]. This mark is
used as a reference for setting the seal.
•
Remove the bearing body installed in step e).
•
Remove the adjusting sleeve installed [3400]
in step d).
•
Remove the bearing bracket [3130] or
adapter bracket installed in step c).
•
Install and set the seal according the
instruction provided with the seal. Inside
component seal may prove difficult to set. If
necessary, remove the casing and impeller
so that the shaft may be moved to allow
access for setting the seal.
•
Repeat steps c), d) and e).
Seals must never be run without
lubrication. Abrasive lubrication will greatly
reduce seal life.
A variety of seal piping plans designed to suit certain
pumping conditions and liquids are available.
6.9.6 Installation of ball bearings and housing
The following steps have previously been performed
for pumps with seals.
a)
Install bearing/adjusting sleeve assembly.
Screw the adjusting sleeve [3400] to the shaft
b) Install O-ring [4610.2] and the bearing body
[3110]. Secure with cap screws [6570.9].
The bearing body contains lip seal [4310.1].
The lip seal is installed with the spring down.
Lubricate the lip seal with grease prior to placing
over the shaft. Fill the cavity between the lips ½
to
⅔ full.
c) Set the impeller as described in section 6.6.3
6.9.7 Installation of motor support head
GP1 and 2 Pumps:
For pumps without seals, attach the support head
[3160] to the upper column [1341.1] with cap screws
[6579.2].
For pumps with seals, attach the support head [3160]
to the bearing bracket [4310.2] with cap screws
[6579.4]
GP3 Pumps:
For pumps without seals, the support head has
already been installed.
For pumps with seals, remove the cap screws
temporarily holding the bearing adapter plate [1340.4]
in place. Attach the support head to the adapter
bracket with cap screws.
6.9.8 Discharge piping
a)
If the strainer [6531] had been removed for
cleaning or replacement purposes, reattach
strainer to suction flange of the casing.
b) Reconnect all bearing lubrication lines [3840.1].
c) For Groups 1, 2, and 6x4-13: At this point the
lower locknut [3400] should be screwed all the
way down the threads on the upper end of the
discharge pipe [1360]. The discharge elbow
[1371] should be screwed onto the lower end of
the discharge pipe (if not already). Check to see
if the companion flange [1245.1] is still
connected to the discharge elbow. Next, the
discharge pipe should be slid up through the
mounting plate [6130] until the companion flange
lines up with the discharge flange of the casing
[1100].
To ensure a proper seal at the casing
discharge flange, it is important that the companion
flange is connected to the casing before the upper
locknuts are tightened to against the mounting plate.
d)
Replace the gasket [4590.2] between the
companion flange and the discharge flange of
the casing and bolt back together.
e) The upper locknut [6580.8] can now be screwed
onto the threads at the upper end of the
discharge pipe and both locknuts can be
tightened against the mounting plate.
f) For Group 3 (excluding 6x4x13): The
discharge pipe is attached the same way to the
casing discharge flange (see step “f” above).
The only difference in the assembly is that the
Group 3 pipes have a flange [1245.3] welded to
the discharge pipe [1360] that bolts to the
underside of the mounting plate [6130].
6.9.9 Final Assembly
•
Ensure ball bearing, line shaft bearings, and seal
lubrication lines are installed
•
Grease the thrust bearing [3031] with initial lube
quantity found in figure 5-5.
•
Follow the installation instruction in section 4.
•
Follow the instruction found in section 5.
•
Ensure all guards are in place.
