Piping – Discharge
• Install a check valve suitable to handle the flow,
liquids and to prevent backflow. After the check valve,
install an appropriately sized gate valve to be used to
regulate the pump capacity, pump inspection and for
maintenance.
• When required, pipe increaser should be installed
between the check valve and the pump discharge.

WIRING AND GROUNDING

Install, ground and wire

according to local and National
Electrical Code Requirements.
Install an all leg disconnect

power before installing or
servicing the pump.
Electrical supply MUST match pump's nameplate
specifications. Incorrect voltage can cause fire,
damage to the motor and voids the warranty.
Motors not protected MUST be provided with
contactors and thermal overloads for single
phase motors, or starters with heaters for three
phase motors. See motor nameplate.
• Use only copper wire to motor and ground. The
ground wire MUST be at least as large as the wire to
the motor. Wires should be color coded for ease of
maintenance.
• Follow motor manufacturer's wiring diagram on the
motor nameplate or terminal cover carefully.

• 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
diameter 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 ADJUST-
MENTS.

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.
