SAFETY APPAREL

• Insulated work gloves when handling hot

bearings or using bearing heater

• Heavy work gloves when handling parts that

have sharp edges, especially impellers

• Safety glasses (with side shields) to protect

eyes, especially in machine shop areas

• Steel-toed shoes to protect feet when han-

dling parts, heavy tools, etc.

• Any other equipment needed to protect

against hazardous/toxic ﬂuids

COUPLING GUARDS

• Never operate a pump without coupling

guards properly installed

FLANGED CONNECTIONS

• Never force piping to make connection with

a pump

• Use only fasteners of proper size and mate-

rial

• Ensure there are no missing fasteners

• Beware of corroded or loose fasteners

OPERATION

• Do not operate below minimum rated ﬂow,

or with suction/discharge valves closed.

• Do not open vent or drain valves, or remove

plugs while the system is pressurized

MAINTENANCE SAFETY

• Always lockout power

• Ensure pump is isolated from the system

and pressure is relived before disassembling

pump, removing plugs, or disconnecting

piping

• Use proper lifting and supporting equipment

to prevent serious injury

• Observe proper decontamination proce-

dures

• Know and follow company safety regula-

tions

• Never apply heat to remove impeller

PUMP SAFETY TIPS

FOREWORD

The design, craftsmanship, and materials used in Gusher pumps provides for optimum performance

and long, trouble-free service. As with any mechanical device, proper use and periodic maintenance

will enhance the performance and life of your pump. This manual is provided as a guideline for proper

installation, operation and maintenance. THIS MANUAL MUST BE READ AND UNDERSTOOD BE-

FORE INSTALLING AND OPERATING ANY PUMP.

GUSHER PUMPS INC. SHALL NOT BE LIABLE FOR PHYSICAL INJURY, DAMAGE OR DELAYS

CAUSED BY A FAILURE TO OBSERVE THE INSTRUCTIONS FOR INSTALLATION, OPERATION, AND

MAINTENANCE CONTAINED IN THIS MANUAL.

WARRANTY

Gusher Pumps, Inc. will replace or repair, within one year of shipment from our plant, any pump in our

judgment that has failed due to defects in materials or workmanship, provided the pump has been

properly installed and maintained and has not been subject to abuse. These pumps must return to

Gusher Pumps, Inc. with complete history of service for inspection and warranty consideration. Gusher

Pumps, Inc. does not accept the responsibility for transportation to and from our plant. Furthermore,

we do not assume any responsibility for consequential damage or loss of production.

WARRANTY IS ONLY VALID WHEN GENUINE GUSHER PARTS ARE USED.

Supervision by an authorized Gusher representative is recommended to ensure proper installation.

Additional manuals can be obtained by contacting your local Gusher representative or by calling

859-824-5001.

PRECAUTIONS

• NEVER apply heat to remove impeller. It may

explode due to trapped liquid.

• NEVER use heat to disassemble pump. Ex-

plosion could occur due to trapped liquid.

• NEVER operate pump without coupling

guard correctly installed.

• NEVER operate pump beyond the rated con-

ditions to which the pump was sold.

• NEVER start pump without proper prime

(sufﬁcient liquid in pump casing).

! WARNING !

Personal injury will result if

procedures outlined in this

manual are not followed.

• NEVER operate pump below recommended

minimum ﬂow or when dry.

• ALWAYS lock out power to the motor before

performing pump maintenance.

• NEVER operate pump without safety devic-

es installed.

• NEVER operate pump with discharge valve

closed.

• NEVER operate pump with suction valve

closed.

• DO NOT change conditions of service with-

out approval of an authorized Gusher repre-

sentative.

NAMEPLATE INFORMATION

On the casing of every Gusher pump is a nameplate that provides information about the pump’s

hydraulic characteristics. This information will be used when ordering spare or replacement parts for

your pump.

RECEIVING and INSPECTION

Gusher Pumps, Inc. has taken great care in

preparing your pump for shipment, however,

due to circumstances beyond our control, your

shipment may be received damaged. There-

fore, we strongly recommend that you take a

few minutes to check your pump upon receipt.

Check for cracked, bent, severely misaligned

(minor misalignments almost always occur

during shipment), or even missing parts. If any

such damage has occurred, you must report it

to the delivering carrier and Gusher Pumps, Inc.

immediately.

We also recommend that you check the model

number, horsepower, current characteristics,

and ft. head of pump received to ensure that you

have received the pump you ordered for your

speciﬁc operating conditions. If you should ﬁnd

some discrepancy, report it to Gusher at once.

If your pump is not going to be installed within

six months, several precautions must be tak-

en;

1. Preservative treatment of bearings and ma-

chined surfaces is required.

2. Remove packing on pumps with packed

stufﬁng box, the stufﬁng box and shaft

sleeve must be oil lubricated to also protect

against moisture.

3. Units equipped with mechanical seals must

also be oil lubricated with an oil can through

the NPT port while rotating the shaft by

hand.

4. Pump suction and discharge ports must be

covered to prevent foreign material from

getting into the pump and causing damage

when pump is started at a later date.

5. Pump must be stored in a dry location.

6. Rotate pump shaft several times every other

month.

OPERATION & MAINTENANCE

• OPERATION

Before starting the pump the reservoir should

be ﬁlled to the minimum level so as to com-

pletely submerge the bottom pump impeller

housing in the liquid which assures priming of

the pump.

Upon initial start up we recommend that you

check and maintain the minimum liquid level

in your reservoir, it is also advisable to check

your piping for leaks at this time. We also rec-

ommend that you check and record the pump

discharge pressure, line voltage and amperage

being drawn by the motor and operating tem-

perature of the bearings. Temperature should

be checked with a pyrometer, do not check by

touch. Temperatures that are hot to the touch

are often well within the maximum operating

temperature of 225OF.

If a problem develops check the trouble shoot-

ing list on page 11. If you are unable to solve

your problem please feel free to contact the

factory.

• MAINTENANCE

Normally after proper installation and under

normal operating conditions (8 hours daily duty

in clean liquid with SG of 1) the pump requires

very little attention.

Before shipment all Gusher pumps have been

tested and greased at the plant, therefore lubri-

cation is not necessary for approximately six to

eight months. Remember, when lubricating ball

bearings that too much grease will cause bear-

ings to run hot, so grease bearings sparingly

when it is necessary. We recommend the use of

Chevron SRI #2 grease.

Because of the vast range of operating condi-

tions it is difﬁcult to recommend one set sched-

ule for periodic maintenance. The more severe

the application the more attention the pump will

require. When a pump operates in a high tem-

perature application (over 1500F) it is recom-

mended to grease the ball bearings sparingly

once a month (approx. 1 gram). In hostile envi-

ronments where abrasives are present the pump

may need to be inspected for wear quarterly.

This should include inspection of the impellers,

bushings and seals. On hostile duty pumps the

lower bushing is constructed of Tungsten Car-

bide. This material is sensitive to thermal shock.

Use caution when rapidly changing the temper-

ature of the liquid. If the temperature change is

too rapid bushing failure will occur.
