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.

WARNING

THE PERFORMANCE OF GOULDS WATER TECHNOLOGY PUMPS IS BASED UPON CLEAR, COLD, FRESH WATER WITH SUCTION CONDITIONS AS SHOWN ON THE PERFORMANCE CURVE. IF USED TO PUMP OTHER LIQUIDS, PUMP PERFORMANCE

Hazardous fluids can cause fire, burns or death.

MAY DIFFER FROM RATED PERFORMANCE BASED ON THE DIFFERENT SPECIFIC GRAVITY, TEMPERATURE, VISCOSITY, ETC. OF THE LIQUID BEING PUMPED. A STANDARD PUMP MAY NOT BE SAFE FOR PUMPING ALL TYPES OF LIQUIDS, SUCH AS TOXIC, VOLATILE OR CHEMICAL LIQUIDS, OR LIQUIDS UNDER EXTREME TEMPERATURES OR PRESSURES.

Please consult Goulds Water Technology catalogs as well as local codes and general references to determine the appropriate pumps for your particular application. Since it is impossible for us to anticipate every application of an Goulds Water Technology pump, if you plan to use the pump for a non-water application, consult Goulds Water Technology beforehand to determine whether such application may be proper or safe under the circumstances. Failure to do so may result in property damage or personal injury.

SAFETY INSTRUCTIONS

TO AVOID SERIOUS OR FATAL PERSONAL INJURY OR MAJOR PROPERTY DAMAGE, READ AND FOLLOW ALL SAFETY INSTRUCTIONS IN

THE MANUAL AND ON THE PUMP.

This is a SAFETY ALERT SYMBOL. When you see this symbol on the pump or in the manual, look for one of the following signal words and be alert to the potential for personal injury or property damage.

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.

• 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.

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.

Coupling Alignment

FAILURE TO DISCONNECT AND LOCKOUT ELECTRICAL POWER 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.)

Check drive coupling alignment. (Refer to Coupling Alignment section for instructions.)

Check motor wiring.

WARNING

1. All electrical work must be done by a licensed electrician.

2. Before working on pump and/or motor be certain the electrical power is off at the main junction box.

Hazardous voltage can shock, burn or cause death.

3. Disconnect the fuse or circuit breaker and have the main switch tagged “DO NOT ENERGIZE THIS

SWITCH, PERSONNEL WORKING

ON EQUIPMENT.”

4. Some motors are equipped with built-in thermal

overloads to shut off the motors in the event the temperature becomes excessive (as a result of mechanical or electrical problems, such as low voltage, poor ventilation, overloaded lines, etc.). These motors will restart automatically as the motor cools down. For safety sake, DO NOT work on any motor without shutting off the electricity.

5. Never operate an electric motor driven pump

without properly grounding the motor frame. Serious injury or death by electrocution could result.

4. Slide bellows assembly on shaft as far as possible, pushing against rubber tail section only. Ease bellows assembly into place. DO NOT DRIVE WITH A HAMMER.

5. Install bellows spring with one end on ﬂange of metal seal ﬂange. Some seal assemblies use a tapered spring. On these, the smaller diameter ﬁts on metal seal ﬂange.

6. Complete assembly of other pump parts. A short “run-in” period may be necessary to provide a

tight seal joint.

CAUTION: Never run a seal dry for any length of time. NOTE: Please make note that all “P” Series pumps are

equipped with shaft sleeve.

SHAFT SLEEVE INSTALLATION (2P, 3P, 4P ONLY)

Follow these instructions when applying loctite between the shaft sleeve and shaft surface.

(a) Surface to be coated with loctite must be free of dirt and grease. Wash with degreasing solvent if necessary.

(b) Spray these surfaces with loctite primer type “T”. DO NOT OVERSPRAY. The thinnest ﬁlm of primer is best. Avoid skin contact or repeated breathing of primer vapor. Allow three to four minutes for primer to dry.

(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.
