APPENDIX II
Installation Instructions for ITT Goulds
ANSI B15.1 Coupling Guards
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. ITT 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 Section V - Preventive
Maintenance.
NOTE: Coupling adjustments should be
completed before proceeding with coupling
guard assembly.
