are found, remove burrs with a smooth mill file,
cleaning thoroughly afterward. Temporarily attach
the top half of the flexible coupling to the motor
shaft.
11. Orient the motor conduit box in the required
position. Align the driver mounting holes with the
mating tapped holes on the discharge head. Lower
the driver until the registers engage and the
driver rests on the thrust pot assembly. Secure

Pump Startup And Operation – SECTION 4
PRE-START PROCEDURE
Consult the applicable manufacturer’s instructions
for detailed information for the prime mover
(electric motor, engine or steam turbine), coupling,
driveshaft, gear driver. Prior to startup, check the
following:
1. Confirm that the following procedures
described in the “Installing the Drivers”
sections have been performed:
A. Wiring of Driver.
B. Driver must rotate counterclockwise (CCW)
when viewed from above.
Do not check motor rotation unless motor
is bolted to pump and drive coupling is
removed.
Be sure to remove all the hand tools and to install the
coupling guards around all exposed shafts and couplings
before start up of the pump. Failure to comply may
result in sever personnel injury or death.
C. Check alignment of pump and driver.
D. Impeller adjustment has been made.
E. Mechanical seal lock collar is attached to shaft.
