INTRODUCTION
Thank You for purchasing a Gorman-Rupp 60
Series Pump. Read this manual carefully to learn
how to safely maintain and service your pump. Fail-
ure to do so could result in personal injury or dam-
age to the pump.
A set of three manuals accompanies your pump.
The Installation/Operation Manual contains essen-
tial information on installing and operating the
pump, and on making electrical connections. The
Parts List Manual provides performance curve(s),
a pump model cross-section drawing, and parts
list for your pump.
This Maintenance and Repair Manual provides
troubleshooting and maintenance instructions re-
quired to properly diagnose operational problems,
and to service the pump hydraulic components.
Contact the factory for the authorized repair facility
closest to you.
This pump is a 60 Series centrifugal pump, with
straight-in suction without a suction check valve.
The pump is designed to handle petroleum prod-
ucts and other clear liquids that do not contain sol-
ids. For specific service, contact your Gorman-
Rupp distributor or the Gorman-Rupp Company.
The basic pump is not furnished with a mounting
base and power source; however, these items are
available from the factory as optional equipment.
The pump is designed to be driven by an explo-
sion-proof motor.
As described on the following page, this manual
will alert personnel to known procedures which re-
quire special attention, to those which could dam-
age equipment, and to those which could be dan-
gerous to personnel. However, this manual cannot
possibly anticipate and provide detailed precau-
tions for every situation that might occur during
maintenance of the unit. Therefore, it is the respon-
sibility of the owner/maintenance personnel to en-
sure that only safe, established maintenance pro-
cedures are used, and that any procedures not ad-
dressed in this manual are performed only after es-
tablishing that neither personal safety nor pump in-
tegrity are compromised by such practices.
If there are any questions regarding the pump
which are not covered in this manual or in other lit-
erature accompanying the unit, please contact
your Gorman-Rupp distributor or the Gorman-
Rupp Company:

SAFETY − SECTION A
The following information applies
throughout this manual to Gorman-
Rupp 60 Series basic pumps.
Because pump installations are seldom
identical, this manual cannot possibly
provide detailed instructions and pre-
cautions for each specific application.
Therefore, it is the owner/installer’s re-
sponsibility to ensure that applications
not addressed in this manual are per-
formed only after establishing that nei-
ther operator safety nor pump integrity
are compromised by the installation.
Before attempting to install, operate, or
service this pump, familiarize yourself
with this manual, and with all other liter-
ature shipped with the pump. Unfamil-
iarity with all aspects of pump operation
covered in this manual could lead to de-
struction of equipment, injury, or death
to personnel.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man-
ual.
2. Shut off the incoming power to the
motor and lock it out or take other
action to ensure that the pump will
remain inoperative.
3. Allow the pump to completely cool
if overheated.
4. Check the temperature before
opening any covers, plates, or
plugs.
5. Close the suction and discharge
valves.
6. Vent the pump slowly and cau-
tiously.
7. Drain the pump.
This pump is designed to handle petro-
leum products and other clear liquids
that do not contain solids. Do not at-
tempt to pump water, corrosive materi-
als, or any liquids which may damage
the pump or endanger personnel as a
result of pump failure.
If this pump is used with volatile and/or
flammable liquids, be certain proper
safety practices are followed before op-
erating or servicing the pump. Provide
adequate ventilation, prohibit smoking,
wear static-resistant clothing and
shoes. Clean up all fuel spills immedi-
ately after occurrence.
Do not operate the pump against a
closed discharge valve for long periods
of time. If operated against a closed dis-
charge valve, pump components will
deteriorate, and the liquid could come
to a boil, build pressure, and cause the
pump casing to rupture or explode.
If this pump is used with volatile and/or
flammable liquids, overheating may
produce dangerous fumes. Take pre-
cautions to ensure the area surrounding

60 SERIES PUMPS MR−04021
PAGE A−2 SAFETY
the pump is adequately ventilated. Al-
low the pump to completely cool and
use extreme caution when venting the
pump, or when removing covers, plates,
plugs, or fittings.
Overheated pumps can cause severe
burns and injuries, and produce explo-
sive fumes. If overheating of the pump
occurs:
1. Stop the pump immediately.
2. Ventilate the area.
3. Allow the pump to completely cool.
4. Check the temperature before
opening any covers, plates,
gauges, or plugs.
5. Vent the pump slowly and cau-
tiously.
6. Refer to instructions in this manual
before restarting the pump.
After the pump has been installed, make
certain that the pump and all piping con-
nections are tight, properly supported
and secure before operation.
Do not install and operate a non-explo-
sion proof motor in an explosive atmo-
sphere. Install, connect, and operate
the motor in accordance with The Na-
tional Electric Code and all local codes.
If there is a conflict between the instruc-
tions in the manual accompanying the
unit and The National Electric Code or
the applicable local code, The National
or local code shall take precedence. All
electrical equipment supplied with this
pump conformed to applicable federal
regulations and national codes in effect
on the date of manufacture.

MAINTENANCE & REPAIR PAGE C − 1
PUMP MAINTENANCE AND REPAIR − SECTION C
Review all SAFETY information in Section A.
Follow the instructions on all tags, label and de-
cals attached to the pump.
Do not attempt to service the pump as-
sembly unless all power to the power
source has been shut off and locked out
or other action taken to ensure that the
pump will remain inoperative; other-
wise, injury or death could result.
Use a lifting device with sufficient ca-
pacity. If slings or chains are used to
move the pump or components, make
sure that the load is balanced; other-
wise serious personal injury or death
could result.
The maintenance and repair instructions in this
manual are keyed to the sectional view and the cor-
responding parts identification list. Refer to the
separate Parts List Manual for replacement parts.
Select a suitable location, preferably indoors, to
perform required maintenance. All work must be
performed by qualified personnel.
This Maintenance and Repair Manual provides
troubleshooting and maintenance instructions re-
quired to properly diagnose operational problems,
and to service the pump hydraulic components.
Check TROUBLESHOOTING, Section B to deter-
mine causes and remedies of pump problems.
Disassemble the pump only as far as required.
Lifting
Use lifting equipment with a capacity of at least
five times the weight of the pump, including the
weight of any options or customer-installed acces-
sories. Suction and discharge hoses or piping
must be removed before attempting to lift the
pump.
For the approximate weight of your pump, refer to
the pump specification data sheet or contact your
Gorman-Rupp distributor or the Gorman-Rupp
Company.
