DANGER
WARNING
CAUTION
You are now the owner of a Goulds Water Technology
pump. This pump was carefully inspected and subjected
to final tests before releasing for shipment. In order to
have maximum performance, please follow the simple
instructions in this manual.
Recommended Precautions
1. If there is a possibility of air being entrapped in the
pump casing, install an automatic venting device to
bleed off the air.
2. All electric motors require a magnetic starter with
current over-load protection.
3. Drain casing completely when servicing pump
handling volatile or harmful liquids. SEE CAUTION.
4. Avoid system pressures that may exceed one and
a half times the operating point selected from the
pump performance curve.
5. Should the fluid temperature rise more than 50ºF
above ambient, expansion joints must be installed on
both the suction and discharge ports to relieve any
stress on the pump casing.
6. All electrical wiring of the pump installation must
be done by a licensed electrician who will observe all
national and local electrical codes.
7. No modifications, additions or deletions should be
made to the pump, without prior approval of the
factory.
8. After servicing the pump, always install the coupling
guards and other safety devices as originally found
prior to disassembly.
9. In systems where shock wave pressures may be
generated, protective devices such as check valves/
gate valves etc., must be installed on discharge line
to prevent shock pressures from entering the pump
casing.
10. In systems containing discharge check valves, gate
valves, etc., pump will not prime against a closed
valve. Check the discharge valves making sure they
are open before attempting to prime pump.
11. Overheated pumps are dangerous. Burns or
explosion could occur due to steam pressure.
Operation pumps with suction and discharge closed
is one cause of severe overheating. If over-heating of
pump casing occurs: 1. Stop pump immediately.
2. Allow pump to cool. 3. Slowly and cautiously
vent pump.
12. Do not use in a combustible atmosphere.
13. Make daily checks of the tightness of suction and
discharge pipe, drain, filter plug and pump gaskets.
Operation should not proceed until all of the above
items have been checked and are tight.
14. This pump is designed primarily for water use.
Before pumping other liquids, READ CAREFULLY
THE FOLLOWING WARNING.

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.
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.

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.
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 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.

BEFORE ATTEMPTING ANY
MAINTENANCE CAN CAUSE
SEVERE PERSONAL INJURY.
FRAME-MOUNTED UNITS ONLY
• Alignment MUST be checked prior to running. See Figure 2.
Parallel
• Use a foot valve or check valve ONLY if necessary for
priming or to hold prime during intermittent duty.
• The suction strainer or suction bell MUST be at least
3 times the suction pipe diameter area.
• Insure that the size and minimum submergence over suction inlet is sufficient to prevent air from entering pump
through a suction vortex. See Figures 3 through 6.
Angular
Figure 2
• Tighten all hold-down bolts before checking alignment.
• If realignment is necessary, always move the motor. Shim
as required.
• Parallel misalignment, shafts with axis parallel but not
concentric. Place dial indicator on one hub and rotate this
hub 360° while taking readings on the outside diameter of
the other hub. Parallel alignment is achieved when reading is
0.010" (0.254 mm) TIR, or less.
• Angular misalignment, shaft with axis concentric but not
parallel. Place dial indicator on one hub and rotate this hub
360° while taking readings on the face of the other hub.
Angular alignment is achieved when reading is 0.020"
(0.508 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.
Piping
• Piping should be no smaller than pump’s discharge and
suction connections and kept as short as possible, avoiding
unnecessary fittings to minimize friction losses.
• All piping MUST be independently supported and MUST
NOT place any piping loads on the pump
NOTICE: DO NOT FORCE PIPING INTO PLACE
AT PUMP SUCTION AND DISCHARGE
CONNECTIONS.
• All pipe joints MUST be airtight.
PIPING – SUCTION
• For suction lifts over 10 ft. (3 m) and liquid temperatures
over 120° F (49° C), consult pump performance curve for
net positive suction head required (NPSHR).
• If a pipe size larger than pump suction is required, an eccentric pipe reducer, with the straight side up, MUST be
installed at the pump suction.
• If pump is installed below the liquid source, install a gate
valve in the suction for pump inspection and maintenance.
NOTICE: DO NOT USE THE GATE VALVE TO
THROTTLE PUMP. THIS MAY CAUSE LOSS
OF PRIME, EXCESSIVE TEMPERATURES
AND DAMAGE TO PUMP, VOIDING
WARRANTY.
• If the pump is installed above the liquid source, the following
MUST be provided:
• To avoid air pockets, no part of the piping should be above
the pump suction connection.
• Slope the piping upward from liquid source.

PIPING – DISCHARGE
• Install a check valve suitable to handle the ow, 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.
AIR RELEASE LINE (4E & 6E)
It is essential to allow the air to escape from the discharge
line to atmosphere during the initial priming and re-priming
cycle. In systems with high discharge heads, it may be advisable
to install an air release line between the pump casing and
discharge check valve to aid their venting. The size of the
air release line is selected such that it does not significantly
affect the discharge capacity. You may install an air release line
through the filler plug hole if necessary. However, the preferred
location is in the discharge line – between the pump and the
discharge check valve – as close to the discharge check valve
as possible. We recommend the following line sizes for the
following pumps:
4" pump – ¾" line
6" pump – 1" line
NOTES:
1. This line size may be increased or decreased depending on
application.
2. Direct the air release line back into the sump (not into
the pump suction line). Leave the end of the line open to
atmosphere. Do not submerge into the liquid being
pumped.
3. The air release line may clog, particularly if a shut-off
valve is installed in the line and is closed during operation.
If this condition occurs, either use a larger line or leave the
shut-off valve open during pumping operation. To aid in
maintaining air release lines, fit them with crosses
instead of elbows.

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.)

to dry.
(c) Apply a coat (.005" or less thick) of loctite 271 (red)
to both shaft and inside of shaft sleeve.
(d) Slide shaft sleeve over the shaft all the way against
shaft shoulder. Make sure the chamfer on the I.D.
of the shaft sleeve is towards the shaft shoulder not
towards the impeller. Allow 5-10 minutes to cure if
primer type “T” is used, or 10-15 minutes if primer is
not used to attain full strength of loctite.
NOTE:
1. An evenly applied coat of loctite on both surfaces
will prevent leakage under shaft sleeve.
2. To remove shaft sleeve heat sleeve surface to
300º-350ºF with heat gun and tap gently on sleeve
to remove.
CHECK VALVE REPLACEMENT
To remove suction check valve follow these steps:
(a) Disconnect suction piping from suction inlet (50).
(b) Remove complete assembly, which includes suction
inlet (50) and check valve assembly.
(c) Remove shoulder bolts (54) to remove check valve
keeper plate (53) and rubber check valve (51).
If any of the parts of the check valve assembly are
damaged i.e. suction inlet (50), check valve (51), shoulder
bolt (54) and keeper plate (53), replace. Make sure the
sealing surface on suction inlet (angled surface) is not
damaged.
NOTE: Latest design check valve uses shoulder bolt (54)
instead of stud, space tube, locking nut, and washer.
Follow above procedure in reverse to reassemble the
pump.
NOTE: Make sure all gaskets, o-ring, rubber check
valve and seal assembly are in good condition before
reassemby. Replace as is necessary.
WINTER STORAGE
1. Wash off exterior of pump.
2. Flush suction line, discharge line, pump casing,
impeller and diffuser of all solids by pumping clear
liquid for a short time.
3. Drain pump casing, suction line and discharge line.
4. If complete draining is impossible add small amount
of anti-freeze into the pump casing. Rotate shaft for
mixing.
5. If the bearings are oil lubricated drain the old oil
from bearing housing and refill housing cavity with
proper grade of oil. (Refer to Maintenance section).
6. Seal off suction and discharge ports of pump casing.
7. Store the units in dry clean area if possible.
8. Motor windings should be protected from excessive
moisture. Follow motor manufacturer’s instructions.
9. Spray interior of pump casing with commercially
available anti-rust and anti-corrosion petroleum
aerosol.
10. Once a month rotate the pump shaft during storage
if possible.
