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
WARNING
OPEN DRIP PROOF MOTORS
IN FLUID CAN CAUSE FIRE,
SHOCK, BURNS OR DEATH.
Hazardous voltage
can shock, burn or
cause death.
OPERATION AT OR NEAR
WARNING
ZERO FLOW CAN CAUSE EX-
TREME HEAT, PERSONAL IN-
JURY OR PROPERTY DAMAGE.
Extreme heat can
cause personal injury
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 flat 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.

• 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 final coupling
alignment can be made within the limits of movement of
motor and by shimming, if necessary.
• Tighten foundation bolts finger 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.
