APPENDIX 6 - COUPLING GAURDS
Installation instructions for Rotech ANSI 1196 Pumps Coupling Guards
Assembly Procedures
1. On the STR, MTR, and LTR, align the end plate (pump end) to the bearing frame. (Impeller adjustment is not required.)
• On the XLR, align the end plate (pump end) to the pump bearing housing with the small slots on the end plate
aligned to the impeller adjusting bolts and the large slots clearing the bearing housing tap bolts. Then attach the
end plate to the bearing housing using the jam nuts on the impeller adjusting bolts as shown in Figure A.
• After attaching the end plate to the bearing housing, check and reset the impeller clearance as detailed in
IMPELLER CLEARANCE SETTING (Page 13).
Fig. A (STR, MTR & LTR)
2. Slightly spread the bottom of the coupling guard half (pump end) and place it over the pump end plate as shown in Figure
D. The annular groove in the guard half is located around the end plate. (See Figure B.)
Before assembling or disassembling the coupling guard, de-energize the motor, lock out the motor
controller/starter, and place a caution tag at the starter indicating that it is disconnected.
Before resuming normal pump operation, replace the coupling guard. Rotech Pump assumes no
liability when these procedures are avoided.
! WARNING !
NOTE: If the end plate (pump end) was previously installed, make any
necessary adjustments to the coupling and skip to Step 2.
NOTE: Complete the coupling adjustments before proceeding
with the coupling guard assembly.
