APPENDIX II
COUPLING GUARD INSTALLATION -
Frame Mounted Only
!
The coupling guard used in an ATEX classified
environment must be constructed from a non-
sparking material.
s
! WARNING
Before assembly or disassembly of the coupling guard is
performed, the motor must be de- energized, the motor
controller/starter put in a locked-out position, and a
caution tag placed at the starter indicating the disconnect.
Replace coupling guard before resuming normal
operation of the pump. Goulds Pumps assumes no
liability for avoiding this practice.
Simplicity of design allows complete assembly of the
coupling guard, including the end plate (pump end), in
about fifteen minutes. If the end plate is already in place,
assembly can be accomplished in about five minutes.
Assembly:
NOTE: If end plate (pump end) is already installed,
make any necessary coupling adjustments and then
proceed to Step 2.
1. STX, MTX, LTX - Align end plate (pump end) to
the bearing frame. (No impeller adjustment
required.)
XLT-X
Align the end plate (pump end) to the pump
bearing housing so that the large slots on the end
plate clear the bearing housing tap bolts and the small
slots are aligned to the impeller adjusting bolts.
Attach the end plate to the bearing housing using the
jam nuts on the impeller adjusting bolts as shown in
Fig. II-3.
After the end plate is attached to the bearing housing,
the impeller clearance must be checked and reset as
explained in the
Preventive Maintenanc e section.
NOTE: Coupling adjustments should be completed
before proceeding with coupling guard assembly.
