Commissioning, Startup, Operation, and Shutdown
Remove the coupling guard
1. Remove the nut, bolt, and washers from the slotted hole in the center of the coupling guard.
2. Slide the driver half of the coupling guard toward the pump.
3. Remove the nut, bolt, and washers from the driver half of the coupling guard.
4. Remove the driver-side end plate.
5. Remove the driver half of the coupling guard:
a) Slightly spread the bottom apart.
b) Lift upwards.
6. Remove the remaining nut, bolt, and washers from the pump half of the coupling guard.
It is not necessary to remove the end plate from the pump side of the bearing housing. You
can access the bearing-housing tap bolts without removing this end plate if maintenance of
internal pump parts is necessary.
7. Remove the pump half of the coupling guard:
a) Slightly spread the bottom apart.
b) Lift upwards.
Check the rotation
WARNING:
• Operating the pump in reverse rotation can result in the contact of metal parts, heat generation, and
breach of containment.
• Always disconnect and lock out power to the driver before you perform any installation or
maintenance tasks. Failure to disconnect and lock out driver power will result in serious physical
injury.
1. Lock out power to the driver.
2. Make sure that the coupling hubs are fastened securely to the shafts.
3. Make sure that the coupling spacer is removed.
The pump ships with the coupling spacer removed.
4. Unlock power to the driver.
5. Make sure that everyone is clear, and then jog the driver long enough to determine that the
direction of rotation corresponds to the arrow on the bearing housing or .
6. Lock out power to the driver.
Couple the pump and driver
WARNING:
• Always disconnect and lock out power to the driver before you perform any installation or
maintenance tasks. Failure to disconnect and lock out driver power will result in serious physical
injury.
•
1. Check the gap between the coupling hubs against the dimensions shown on the elevation
drawing or as stamped on the coupling hub. For any necessary adjustment, move the
driver not the pump.
Motors with sleeve bearings may be manufactured with 1/4 or 1/2 in. (6.35 or 12.7 mm) end
movement (float) in the motor rotor. For limited end-float arrangement, the gap between the
coupling halves must be set in a different manner. If specific directions are not indicated in
the motor instructions, then follow this procedure:
NOTICE:
If the driver was mounted at the factory, the setting for the coupling is already determined.
