INTRODUCTION
Thank You for purchasing a Gorman-Rupp pump.
Read this manual carefully to learn how to safely
install and operate your pump. Failure to do so
could result in personal injury or damage to the
pump.
This pump is a 10 Series, semi-open impeller, selfpriming centrifugal model with a suction check
valve. It is close-coupled to a single cylinder Honda
gasoline engine, Model GX270. The pump is designed for handling dirty water containing specified entrained solids. The basic material of construction for wetted parts is aluminum, with ductile
iron impeller and steel wearing parts.
If there are any questions regarding the pump or its
application which are not covered in this manual or
in other literature accompanying this unit, please
contact your Gorman-Rupp distributor, or The Gorman-Rupp Company:

The following are used to alert maintenance personnel to procedures which require special attention, to those which could damage equipment, and
to those which could be dangerous to personnel:
Immediate hazards which WILL result in
severe personal injury or death. These
instructions describe the procedure required and the injury which will result
from failure to follow the procedure.
Hazards or unsafe practices which
COULD result in severe personal injury
or death. These instructions describe
the procedure required and the injury
which could result from failure to follow
the procedure.
Hazards or unsafe practices which COULD
result in minor personal injury or product
or property damage. These instructions
describe the requirements and the possible damage which could result from failure
to follow the procedure.
For information or technical assistance on the engine, contact the engine manufacturer’s local
dealer or representative.

SAFETY − SECTION A
This information applies to 10 Series engine driven pumps. Refer to the manual
accompanying the engine before attempting to begin operation.
Because pump installations are seldom
identical, this manual cannot possibly
provide detailed instructions and precautions for each specific application.
Therefore, it is the owner/installer’s responsibility to ensure that applications
not addressed in this manual are performed only
after establishing that neither operator safety nor pump integrity
are compromised by the installation.
Before attempting to open or service the
pump:
1. Familiarize yourself with this manual.
2. Shut down the engine and disconnect the spark plug wire 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 cautiously.
7. Drain the pump.
This pump is designed to handle dirty
water containing specified entrained
solids. Do not attempt to pump volatile,
corrosive, or flammable liquids which
may damage the pump or endanger personnel as a result of pump failure.
Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or damage to equipment. Suction and discharge hoses and piping must be removed from the pump before lifting.
After the pump has been positioned,
make certain that the pump and all piping connections are tight, properly supported and secure before operation.
Do not operate the pump against a
closed discharge valve for long periods
of time. If operated against a closed discharge valve, pump components will
deteriorate, and the liquid could come
to a boil, build pressure, and cause the
pump casing to rupture or explode.
Do not remove plates, covers, gauges,
pipe plugs, or fittings from an overheated pump. Vapor pressure within the
pump can cause parts being disengaged to be ejected with great force. Allow the pump to cool before servicing.
PAGE A − 1SAFETY
OM−06215
10 SERIES
Do not operate an internal combustion
engine in an explosive atmosphere.
When operating internal combustion
engines in an enclosed area, make certain that exhaust fumes are piped to the
outside. These fumes contain carbon
monoxide, a deadly gas that is colorless, tasteless, and odorless.
Fuel used by internal combustion engines presents an extreme explosion
and fire hazard. Make certain that all
fuel lines are securely connected and
free of leaks. Never refuel a hot or running engine. Avoid overfilling the fuel
tank. Always use the correct type of fuel.
Never tamper with the governor to gain
more power. The governor establishes
safe operating limits that should not be
exceeded. The maximum continuous
operating speed for this pump is 3600
RPM.

10 SERIES OM−06215
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 arrange the pump and piping.
Most of the information pertains to a standard
static lift application where the pump is positioned
above the free level of liquid to be pumped.
If installed in a flooded suction application where
the liquid is supplied to the pump under pressure,
some of the information such as mounting, line
configuration, and priming must be tailored to the
OUTLINE DRAWING
specific application. Since the pressure supplied
to the pump is critical to performance and safety,
be sure to limit the incoming pressure to 50% of the
maximum permissible operating pressure 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 dimensions of this pump.
Figure 1. Pump Models 13D1−GX270
PREINSTALLATION INSPECTION
The pump assembly was inspected and tested before shipment from the factory. Before installation,
inspect the pump for damage which may have occurred 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 drying, check for loose hardware at mating surfaces.
PAGE B − 1INSTALLATION
OM−06215 10 SERIES
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
AND REPAIR section of this manual and perform duties as instructed.
e. If the pump and
more than 12 months, some of the components or lubricants may have exceeded their
maximum shelf life. These must be inspected
or replaced 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 determine the repair or updating policy. Do not put the
pump into service until appropriate action has
been taken.

POSITIONING PUMP
The pump assembly can be seriously
damaged if the cables or chains used to lift
and move the unit are improperly wrapped
around the pump.
Mounting
Locate the pump in an accessible place as close as
practical to the liquid being pumped. Level mounting is essential for proper operation.
The pump may have to be supported or shimmed
to provide for level operation or to eliminate vibration.
To ensure sufficient lubrication and fuel supply to
the engine, do not position the pump and engine
more than 15_ off horizontal for continuous operation. The pump and engine may be positioned up
to 30_ off horizontal for intermittent operation
only; however, the engine manufacturer should be
consulted for continuous operation at angles
greater than 15_.
Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or damage to equipment. The bail is intended
for use in lifting the pump assembly
only. Suction and discharge hoses and
piping must be removed from the pump
before lifting.
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.
Clearance
When positioning the pump, allow a minimum
clearance of 18 inches (457 mm) in front of the
back cover to permit removal of the cover and easy
access to the pump interior.
SUCTION AND DISCHARGE PIPING
Pump performance is adversely effected by increased suction lift, discharge elevation, and friction losses. See the performance curve and notes
on Page E-1 to be sure your overall application allows pump to operate within the safe operation
range.
Materials
Either pipe or hose maybe used for suction and
discharge lines; however, the materials must be
compatible with the liquid being pumped. If hose is
used in suction lines, it must be the rigid-wall, rein-
