Wiring and Grounding

Install, ground and wire according

to local and National Electrical Code

Requirements.

Install an all leg electrical power

disconnect switch near the pump.

Disconnect and lockout electrical

power before installing or servicing

the pump.

Electrical supply MUST match

pump’s nameplate specications. In-

correct voltage can cause ﬁre, damage

motor and void the warranty.

Motors without built-in protection 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.

FAILURE TO PERMANENTLY

GROUND THE PUMP, MOTOR AND

CONTROLS BEFORE CONNECTING

TO ELECTRICAL POWER CAN CAUSE

SHOCK, BURNS OR DEATH.

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. For frame mounted units, switch power

on and off quickly to observe rotation. On close coupled

units, remove motor end plug or cover to observe rotation.

• To reverse three phase motor rotation, interchange any two

power supply leads.

Impeller Running Clearance (6E1 Only)

(Applicable for models with open impellers)

The impeller running clearance, the distance between the

impeller vanes and diffuser is adjusted at the factory prior

to shipment to .020"-.030". To adjust this clearance in the

ﬁeld, shut down the pump, disconnect power supply to

the pump and use the following instructions.

1. Unscrew three jack-screws (112), jam-nuts (111) and

bearing carrier capscrews (45).

2. Adjust the jack-screws and capscrews until the

impeller just touches the diffuser (46) (slight rub).

Tighten the jam nuts.

3. Measure the gap between bearing housing surface

(coupling END) and bearing carrier ﬂange.

4. Adjust jack-screws, jam-nuts and capscrews to

pull out the rotating assembly, until the gap between

bearing housing surface and bearing carrier ﬂange

measures .020"-.030" more than previously

measured gap.

NOTE: Tightening the jack-screws will increase the front

clearance and tightening the capscrews will decrease the

front clearance.

Tighten one set of screws and loosen the other to go in

the direction required. Tighten locknut (111).

NOTE: Maximum allowable bearing carrier (110) pull

back movement is

", (i.e. from the condition when

impeller is “just” touching the diffuser you can push back

Operation

DO NOT OPERATE FRAME MOUNTED

OR SAE 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.

STARTING

Follow the motor manufacturer’s instructions carefully.

Before starting ﬁll the pump casing with liquid through

the priming plug provided. Your pump has been designed

to prime itself in a few minutes. High suction lifts require

additional time and reduce the performance of the pump.

Should you have difﬁculty, refer to the “Troubleshooting

Guide” table.

Goulds Water Technology self-priming pumps prime

and reprime themselves providing the casing is ﬁlled

with liquid. Should you lose this liquid from the casing

accidentally or by draining purposely, it will be necessary

to reﬁll it with liquid before starting.

2P through 4P – Check grease in the bearing housing

cavity. Units are shipped with grease but should be

checked before starting. (Refer to Lubrication section for

more details.)

4E and 6E – Units are shipped without oil in the bearing

housing cavity. Fill this cavity with the proper amount

and proper grade of oil. (Refer to Lubrication section for

more details.)

Extreme heat can

cause personal injury

or property damage.
