PAGE I - 1INTRODUCTION
6500 SERIES
SAFETY ‐ SECTION A
This information applies to 6500 Series
basic pumps. Gorman‐Rupp has no
control over or particular knowledge of
the power source which will be used.
Refer to the manual accompanying the
power source before attempting to be
gin operation.
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.
OM-06682
Death or serious personal injury and
damage to the pump or components
can occur if proper lifting procedures
are not observed. Make certain that
hoists, chains, slings or cables are in
good working condition and of suffi
cient capacity and that they are posi
tioned so that loads will be balanced
and the pump or components will not be
damaged when lifting. Suction and dis
charge hoses and piping must be re
moved from the pump before lifting. Lift
the pump or component only as high as
necessary and keep personnel away
from suspended objects.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man
ual.
2. Lock out or disconnect the power
source 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.
After the pump has been installed, make
certain that the pump and all piping or
hose connections are tight, properly
supported and secure before operation.
Do not operate the pump without the
shields and/or guards in place over the
drive shaft, belts, and/or couplings, or
other rotating parts. Exposed rotating
parts can catch clothing, fingers, or
tools, causing severe injury to person
nel.
Do not operate the pump against a
closed discharge valve for long periods
of time. If operated against a closed dis
PAGE A - 1SAFETY
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.
Overheated pumps can cause severe
burns and injuries. 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.
6500 SERIESOM-06682
Do not remove plates, covers, gauges,
pipe plugs, or fittings from an over
heated pump. Vapor pressure within the
pump can cause parts being disen
gaged to be ejected with great force. Al
low the pump to completely cool before
servicing.
Never run this pump backwards. Be cer
tain that rotation is correct before fully
engaging the pump.
Pumps and related equipment must be in
stalled and operated according to all na
tional, local and industry standards.
PAGE A - 2 SAFETY
6500 SERIES OM-06682
INSTALLATION - SECTION B
Review all SAFETY information in Section A.
Since pump installations are seldom identical, this
section offers only general recommendations and
practices required to inspect, position, and ar
range the pump and piping.
Most of the information pertains to a flooded suc
tion application where the liquid is supplied to the
pump under pressure. Since the pressure sup
plied to the pump is critical to performance and
safety, be sure to limit the incoming pressure to
OUTLINE DRAWING
50% of the maximum permissible operating pres
sure as shown on the pump performance curve
(see Section E, Page 1).
For further assistance, contact your Gorman‐Rupp
distributor or the Gorman‐Rupp Company.
Pump Dimensions
See Figure 1 for the approximate physical dimen
sions of this pump.

PREINSTALLATION INSPECTION
The pump assembly was inspected and tested be
fore shipment from the factory. Before installation,
inspect the pump for damage which may have oc
curred during shipment. Check as follows:
a. Inspect the pump and engine for cracks,
dents, damaged threads, and other obvious
damage.
b. Check for and tighten loose attaching hard
ware. Since gaskets tend to shrink after dry
ing, check for loose hardware at mating sur
faces.
c. Carefully read all tags, decals, and markings
on the pump assembly, and perform all duties
indicated.
d. Check levels and lubricate as necessary. Re
fer to LUBRICATION in the MAINTENANCE
PAGE B - 1INSTALLATION
OM-06682 6500 SERIES
AND REPAIR section of this manual and per
form duties as instructed.
e. If the pump has been stored for more than 12
months, some of the components or lubri
cants may have exceeded their maximum
shelf life. These must be inspected or re
placed to ensure maximum pump service.
If the maximum shelf life has been exceeded, or if
anything appears to be abnormal, contact your
Gorman‐Rupp distributor or the factory to deter
mine the repair or updating policy. Do not put the
pump into service until appropriate action has
been taken.
POSITIONING PUMP
Death or serious personal injury and
damage to the pump or components
can occur if proper lifting procedures
are not observed. Make certain that
hoists, chains, slings or cables are in
good working condition and of suffi
cient capacity and that they are posi
tioned so that loads will be balanced
and the pump or components will not be
damaged when lifting. Suction and dis
charge hoses and piping must be re
moved from the pump before lifting. Lift
the pump or component only as high as
necessary and keep personnel away
from suspended objects.
Mounting
Locate the pump in an accessible place as close as
practical to the liquid being pumped. Level mount
ing is essential for proper operation.
Proper mounting of the pump, driver and base is
critical to the performance of the pump. Improper
mounting can result in vibration, which can cause
damage to the pump and/or other system compo
nents.
The pumping unit must be securely mounted to a
foundation that is heavy enough to absorb any vi
bration, strain or shock, while providing perma
nent, rigid support for the unit.
Because pump installations vary due to the specif
ic application, this manual cannot possibly antici
pate and provide detailed instructions for every in
stallation. Therefore, it is recommended that the in
staller of the unit follow the recommendations pro
vided by the Hydraulic Institute in their Rotodynam
ic Centrifugal Pump Design and Application manu
al when designing and fabricating the foundation
upon which the pump, base and driver will be
mounted.
SUCTION AND DISCHARGE PIPING
The following is provided as general information for
suction and discharge piping. Because pump in
stallations vary due to the specific application, this
manual cannot possibly anticipate and provide de
tailed instructions for every installation. Therefore,
it is recommended that the installer follow the rec
ommendations provided by the Hydraulic Institute
in their Pump Piping for Rotodynamic Pumps man
ual for layout, design and installation of the system
piping.
Materials
Lifting
Pump unit weights will vary depending on the
mounting and drive provided. Check the shipping
tag on the unit packaging for the actual weight, and
use lifting equipment with appropriate capacity.
Drain the pump and remove all customer‐installed
equipment such as suction and discharge hoses
or piping before attempting to lift existing, installed
units.
PAGE B - 2 INSTALLATION
Materials used in piping must be compatible with
the liquid being pumped. Using piping couplings
in suction lines is not recommended.
Line Configuration
Keep suction and discharge lines as straight as
possible to minimize friction losses. Make mini
mum use of elbows and fittings, which substan
tially increase friction loss. If elbows are necessary,
use the long‐radius type to minimize friction loss.
