CHECK ROTATION
NOTE: Serious damage may result if pump is run in
the wrong rotation.
1.
Lock out power to driver.
s
!
WARNING
Before installation or disassembly of the coupling
guard is performed, the driver must be de-energized,
the driver controller/starter put in a locked out position
and a caution tag placed at the controller/starter
indicating the disconnect. Replace coupling guard
before resuming normal operation of the pump or
serious physical injury may occur. Goulds Pumps, Inc.
assumes no liability for avoiding the practice.
2.
Make sure coupling hubs are securely fastened to
shafts.
NOTE: Pump is shipped with coupling spacer removed.
3.
Unlock driver power.
4.
Make sure everyone is clear. Jog driver just long
enough to determine direction of rotation. Rotation
must correspond to arrow on bearing housing.
5.
Lock out power to driver.
CHECK IMPELLER AXIAL
CLEARANCE
l
!
CAUTION
The impeller clearance setting procedure must be
followed. Improperly setting the clearance can result in
equipment damage and heat generation casing failure.
The proper impeller axial clearance is required for proper
air removal and efficient pump operation. See the
maintenance section of this manual for the correct clearance
and method of setting.
COUPLE PUMP AND DRIVER
s
!
WARNING
Before installation or disassembly of the coupling
guard is performed, the driver must be de-energized,
the driver controller/starter put in a locked out position
and a caution tag placed at the controller/starter
indicating the disconnect. Replace coupling guard
before resuming normal operation of the pump or
serious physical injury may occur. Goulds Pumps, Inc.
assumes no liability for avoiding the practice.
l
!
CAUTION
Use of couplings which have excessive weight can
cause shaft failure and lead to physical injury. Consult
pump manufacturer for recommended weight limits for
couplings should the originally supplied coupling be
changed.
1.
Install and lubricate coupling per manufacturer’s
instructions.
2.
Install coupling guard (Fig. 16).
s
!
WARNING
Pump shall never be operated without coupling guard
installed correctly.
