Hazardous machinery

can cause personal

injury or death.

WARNING

Operating Instructions

NOTICE: INSPECT UNIT FOR DAMAGE AND

REPORT ALL DAMAGE TO CARRIER

IMMEDIATELY.

LOCATION

By placing your Goulds Water Technology pump on a

ﬁrm, level foundation, you reduce harmful vibrations and

unnecessary noise. Your Goulds Water Technology pump is

self-priming, must be mounted horizontally and may be located

above the source of liquid supply. Best pump operation is

obtained by locating the pump as close as possible to the liquid

being handled. Keep in mind a pump can push liquid more

effectively than it can pull or draw liquid. The actual priming

ability of a pump depends upon many factors such as the size

and layout of the piping, the type of liquid and its temperature,

the speciﬁc pump selected and its speed of operation.

Additional priming information is given in the Goulds Water

Technology Sales Catalog. Provide the necessary space around

the pump for future inspection and servicing of the unit.

Protect the pump and piping from freezing temperatures.

CONNECTIONS

Connections at the easily accessible suction and discharge

ports can be made either with hose or pipe. The use of

strongly reinforced suction hose will prevent collapsing

of the hose during operation. New hose washers should

be used at the couplings to prevent trouble-causing leaks.

All hose or pipe should be independently supported to

eliminate excessive strain on the pump.

ROTATION

Your pump is speciﬁcally designed to rotate in a clockwise

direction when viewed from the coupling end of the pump

shaft. Three phase motors can rotate in either direction.

Interchanging any two leads of a three phase will reverse

the rotation. Check your rotation. (Also refer to cast

rotation arrow on pump casing.)

SPLASHING OR IMMERSING

OPEN DRIP PROOF MOTORS

IN FLUID CAN CAUSE FIRE,

SHOCK, BURNS OR DEATH.

OPERATION AT OR NEAR

ZERO FLOW CAN CAUSE EX-

TREME HEAT, PERSONAL IN-

JURY OR PROPERTY DAMAGE.

NOTICE: NO NOT RUN PUMP DRY OR SEAL

DAMAGE WILL RESULT.

• After stabilizing the system at normal operating conditions,

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 following procedures and

hazard warnings in “COUPLING ALIGNMENT” section

of this manual.

FRAME-MOUNTED UNITS

• A at substantial foundation surface MUST be provided to

avoid distortion and/or strain when tightening the foundation

bolts. A rubber mounting is acceptable to reduce noise or

excessive vibration.

• Tighten motor hold-down bolts BEFORE connecting piping

to pump.

Figure 1

• It is recommended that the baseplate be grouted to a

foundation with solid footing. Refer to Figure 1.

• Place unit in position on wedges located at four points, two

below approximate center of driver and two below

approximate center of pump. Adjust wedges to level unit.

Level or plumb suction and discharge connections.

• Make sure bedplate is not distorted and nal coupling

alignment can be made within the limits of movement of

motor and by shimming, if necessary.

• Tighten foundation bolts nger tight and build dam around

foundation. Pour grout under bedplate making sure the areas

under the pump and motor feet are ﬁlled solid. Allow grout

to harden 48 hours before fully tightening foundation bolts.

• Tighten pump and motor hold-down bolts before aligning

shaft or connecting the piping to pump.

• Allow grout to harden for 48 hours before tightening 4

foundation bolts.

CLOSE-COUPLED UNITS

• Units must be installed horizontally.

• The motor feet MUST be bolted to a substantial surface that

is capable of complete and rigid support for the pump and

motor.
