Alignment MUST be checked prior to running. See
Figure 6.
Tighten all hold-down bolts before checking the align-
ment.
If realignment is necessary, always move the motor.
Shim as required.
Figure 6
Parallel misalignment (shafts with axis parallel but not
concentric). Place dial indicator on one hub and rotate
this hub 360º while taking readings on the outside di-
ameter of the other hub. Parallel alignment is achieved
when reading is 0.005” (0.127 mm) TIR, or less.
Angular misalignment (shaft with axis concentric but
not parallel). Place dial indicator on one hub and
rotate this hub 360º while taking readings on the face
of the other hub. Angular alignment is achieved when
reading is 0.005” (0.127 mm) TIR, or less.
Final alignment is achieved when parallel and angular
requirements are satisfied with motor hold-down bolts
tight.
NOTICE: ALWAYS RECHECK BOTH ALIGNMENTS
AFTER MAKING ANY MECHANICAL
ADJUSTMENTS.
ROTATION
NOTICE: INCORRECT ROTATION MAY CAUSE
DAMAGE TO THE PUMP AND VOIDS
THE WARRANTY.
Correct rotation is right-hand, CLOCKWISE when
viewed from the motor end. Remove motor end plug
or cover to observe rotation.
To reverse three phase motor rotation, interchange
any two power supply leads.
OPERATION
DO NOT OPERATE FRAME
MOUNTED UNITS WITHOUT SAFETY
GUARDS IN PLACE OR SEVERE
PERSONAL INJURY MAY RESULT.
SPLASHING OR IMMERSING OPEN
DRIP PROOF MOTORS IN FLUID
CAN CAUSE FIRE, SHOCK, BURNS
OR DEATH.
OPERATION AT OR NEAR ZERO
FLOW CAN CAUSE EXTREME HEAT,
PERSONAL INJURY OR PROPERTY
DAMAGE.
NOTICE: NO NOT RUN PUMP DRY OR SEAL
DAMAGE WILL RESULT.
After stabilizing the system at normal operating condi-
tions, check the piping. If necessary, adjust the pipe
supports.
On frame-mounted units, coupling alignment may
have changed due to the temperature differential
between pump and motor. Recheck alignment follow-
ing procedures and hazard warnings in “COUPLING
ALIGNMENT” section of this manual.
MAINTENANCE
FAILURE TO DISCONNECT AND
LOCKOUT ELECTRICAL POWER
BEFORE ATTEMPTING ANY
MAINTENANCE CAN CAUSE
SHOCK, BURNS OR DEATH.
FAILURE TO RELIEVE SYSTEM
PRESSURE AND DRAIN SYSTEM
BEFORE ATTEMPTING ANY
MAINTENANCE CAN CAUSE
PROPERTY DAMAGE, PERSONAL
INJURY OR DEATH.
Close-Coupled Units:
Bearings are located in and are part of the motor. For
lubrication information, refer to motor manufacturer’s
instructions.
Frame-Mounted Units:
Pump bearing frames have greased for life bearings.
No lubrication is possible or necessary.
Follow motor and coupling manufacturer’s lubrication
instructions.
