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 take
precautions 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−05463
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.

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

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.
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:
Figure 1. Pump Models 13D1−19
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
Page 9
OM−05463 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.
engine have been stored for
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
Use lifting equipment with a capacity of at least 650
pounds (295 kg.). The pump weighs approxi-
mately 130 pounds (59 kg.) not including the
weight of accessories or suction and discharge
piping. Customer installed equipment such as suction and discharge piping must be removed before
attempting to lift.
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-
PAGE B − 2 INSTALLATION
Page 10
10 SERIES OM−05463
forced type to prevent collapse under suction. 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 minimum use of elbows and fittings, which substantially increase friction loss. If elbows are necessary,
use the long-radius type to minimize friction loss.
Connections to Pump
Before tightening a connecting flange, align it exactly with the pump port. Never pull a pipe line into
place by tightening the flange bolts and/or couplings.
Lines near the pump must be independently supported to avoid strain on the pump which could
cause excessive vibration, decreased bearing life,
and increased shaft and seal wear. If hose-type
lines are used, they should have adequate support
to secure them when filled with liquid and under
pressure.
Fittings
Suction lines should be the same size as the pump
inlet. If reducers are used in suction lines, they
should be the eccentric type, and should be installed with the flat part of the reducers uppermost
to avoid creating air pockets. Valves are not normally used in suction lines, but if a valve is used,
install it with the stem horizontal to avoid air pockets.
Strainers
If a strainer is furnished with the pump, be certain
to use it; any spherical solids which pass through a
strainer furnished with the pump will also pass
through the pump itself.
If a strainer is not furnished with the pump, but is
installed by the pump user, make certain that the
total area of the openings in the strainer is at least
three or four times the cross section of the suction
line, and that the openings will not permit passage
of solids larger than the solids handling capability
of the pump.
This pump is designed to handle up to 1 1/2-inch
(38,1 mm) diameter spherical solids.
Gauges
Most pumps are drilled and tapped for installing
discharge pressure and vacuum suction gauges. If
these gauges are desired for pumps that are not
tapped, drill and tap the suction and discharge
lines not less than 18 inches (457 mm) from the
suction and discharge ports and install the lines.
Installation closer to the pump may result in erratic
readings.
SUCTION LINES
To avoid air pockets which could affect pump priming, the suction line must be as short and direct as
possible. When operation involves a suction lift, the
line must always slope upward to the pump from
the source of the liquid being pumped; if the line
slopes down to the pump at any point along the
suction run, air pockets will be created.
Sealing
Since even a slight leak will affect priming, head,
and capacity, especially when operating with a
high suction lift, all connections in the suction line
should be sealed with pipe dope to ensure an airtight seal. Follow the sealant manufacturer’s recommendations when selecting and applying the
pipe dope. The pipe dope should be compatible
with the liquid being pumped.
Suction Lines In Sumps
If a single suction line is installed in a sump, it
should be positioned away from the wall of the
sump at a distance equal to 1-1/2 times the diameter of the suction line.
If there is a liquid flow from an open pipe into the
sump, the flow should be kept away from the suction inlet because the inflow will carry air down into
the sump, and air entering the suction line will reduce pump efficiency.
PAGE B − 3INSTALLATION
Page 11
OM−05463 10 SERIES
If it is necessary to position inflow close to the suction inlet, install a baffle between the inflow and the
suction inlet at a distance 1-1/2 times the diameter
of the suction pipe. The baffle will allow entrained
air to escape from the liquid before it is drawn into
the suction inlet.
If two suction lines are installed in a single sump,
the flow paths may interact, reducing the efficiency
of one or both pumps. To avoid this, position the
suction inlets so that they are separated by a distance equal to at least 3 times the diameter of the
suction pipe.
Suction Line Positioning
The depth of submergence of the suction line is
critical to efficient pump operation.
recommended minimum submergence vs. veloc-
ity.
Figure 2 shows
NOTE
The pipe submergence required may be reduced
by installing a standard pipe increaser fitting at the
end of the suction line. The larger opening size will
reduce the inlet velocity. Calculate the required
submergence using the following formula based
on the increased opening size (area or diameter).
Figure 2. Recommended Minimum Suction Line Submergence vs. Velocity
DISCHARGE LINES
Siphoning
Do not terminate the discharge line at a level lower
than that of the liquid being pumped unless a siphon breaker is used in the line. Otherwise, a siphoning action causing damage to the pump
could result.
PAGE B − 4 INSTALLATION
Valves
If a throttling valve is desired in the discharge line,
use a valve as large as the largest pipe to minimize
friction losses. Never install a throttling valve in a
suction line.
A check valve in the discharge line is normally recommended, but it is not necessary in low discharge head applications.
Page 12
10 SERIES OM−05463
With high discharge heads, it is recommended that
a throttling valve and a system check valve be installed in the discharge line to protect the pump
from excessive shock pressure and reverse rotation when it is stopped.
If the application involves a high discharge
head, gradually close the discharge
throttling valve before stopping the pump.
Bypass Lines
If a system check valve is used due to high discharge head, it may be necessary to vent trapped
air from the top of the pump during the priming
process. This may be accomplished by installing a
bypass line from the top of the pump, back to the
source of liquid. The end of the bypass line must be
submerged. The line must be large enough to prevent clogging, but not so large as to affect pump
discharge capacity.

OPERATION − SECTION C
Review all SAFETY information in Section A.
Follow the instructions on all tags, labels and
decals attached to 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.
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 4000
RPM.
Add liquid to the pump casing when:
1. The pump is being put into service for the
first time.
2. The pump has not been used for a considerable length of time.
3. The liquid in the pump casing has evaporated.
Once the pump casing has been filled, the pump
will prime and reprime as necessary.
After filling the pump casing, reinstall
and tighten the fill plug. Do not attempt
to operate the pump unless all connecting piping is securely installed. Otherwise, liquid in the pump forced out under pressure could cause injury to personnel.
To fill the pump, remove the pump casing fill cover
or fill plug in the top of the casing, and add clean
liquid until the casing is filled. Replace the fill cover
or fill plug before operating the pump.
PRIMING
Install the pump and piping as described in INSTALLATION. Make sure that the piping connec-
tions are tight, and that the pump is securely
mounted. Check that the pump is properly lubricated (see LUBRICATION in MAINTENANCE
AND REPAIR).
This pump is self-priming, but the pump should
never be operated unless there is liquid in the
pump casing.
Never operate this pump unless there is
liquid in the pump casing. The pump will
not prime when dry. Extended operation of
a dry pump will destroy the seal assembly.
STARTING
Consult the operations manual furnished with the
engine.
OPERATION
Pump speed and operating condition
points must be within the continuous performance range shown on the curve. (See
Section E, Page 1.)

line. Air from the suction line will be discharged
through the bypass line back to the wet well during
the priming cycle. When the pump is fully primed
and liquid is flowing steadily from the bypass line,
open the discharge throttling valve. Liquid will then
continue to circulate through the bypass line while
the pump is in operation.

gaged to be ejected with great force. Allow the pump to cool before servicing.
Open all valves in the discharge line and start the
engine. Priming is indicated by a positive reading
on the discharge pressure gauge or by a quieter
operation. The pump may not prime immediately
because the suction line must first fill with liquid. If
the pump fails to prime within five minutes, stop it
and check the suction line for leaks.
After the pump has been primed, partially close the
discharge line throttling valve in order to fill the line
slowly and guard against excessive shock pressure which could damage pipe ends, gaskets,
sprinkler heads, and any other fixtures connected
to the line. When the discharge line is completely
filled, adjust the throttling valve to the required flow
rate.
Leakage
No leakage should be visible at pump mating surfaces, or at pump connections or fittings. Keep all
line connections and fittings tight to maintain maximum pump efficiency.
Liquid Temperature And Overheating
The maximum liquid temperature for this pump is
110_ F (43_C). Do not apply it at a higher operating
temperature.
Overheating can occur if operated with the valves
in the suction or discharge lines closed. Operating
against closed valves could bring the liquid to a
boil, build pressure, and cause the pump to rupture or explode. If overheating occurs, stop the
pump and allow it to cool before servicing it. Refill
the pump casing
with cool liquid.
Strainer Check
If a suction strainer has been shipped with the
pump or installed by the user, check the strainer
regularly, and clean it as necessary. The strainer
should also be checked if pump flow rate begins to
drop. If a vacuum suction gauge has been installed, monitor and record the readings regularly
to detect strainer blockage.
Never introduce air or steam pressure into the
pump casing or piping to remove a blockage. This
could result in personal injury or damage to the
equipment. If backflushing is absolutely necessary, liquid pressure must be limited to 50% of the
maximum permissible operating pressure shown
on the pump performance curve (see Section E,
Page 1).
Pump Vacuum Check
With the pump inoperative, install a vacuum gauge
in the system, using pipe dope on the threads.
Block the suction line and start the pump. At operating speed the pump should pull a vacuum of 20
inches (508 mm) or more of mercury. If it does not,
check for air leaks in the seal, gasket, or discharge
valve.
Open the suction line, and read the vacuum gauge
with the pump primed and at operation speed.
Shut off the pump. The vacuum gauge reading will
immediately drop proportionate to static suction
lift, and should then stabilize. If the vacuum reading
falls off rapidly after stabilization, an air leak exists.
Before checking for the source of the leak, check
the point of installation of the vacuum gauge.
STOPPING
Never halt the flow of liquid suddenly. If the liquid
being pumped is stopped abruptly, damaging
OPERATIONPAGE C − 2

shock waves can be transmitted to the pump and
piping system. Close all connecting valves slowly.
On engine driven pumps, reduce the throttle
speed slowly and allow the engine to idle briefly before stopping.
If the application involves a high discharge
head, gradually close the discharge
throttling valve before stopping the pump.
After stopping the pump, remove the engine ignition key to ensure that the pump will remain inoperative.
Cold Weather Preservation
In below freezing conditions, drain the pump to
prevent damage from freezing. Also, clean out any
solids by flushing with a hose. Operate the pump
for approximately one minute; this will remove any
remaining liquid that could freeze the pump rotating parts. If the pump will be idle for more than a
few hours, or if it has been pumping liquids containing a large amount of solids, drain the pump,
and flush it thoroughly with clean water. To prevent
large solids from clogging the drain port and preventing the pump from completely draining, insert
a rod or stiff wire in the drain port, and agitate the
liquid during the draining process. Clean out any
remaining solids by flushing with a hose.

PREVENTIVE MAINTENANCE
Since pump applications are seldom identical, and
pump wear is directly affected by such things as
the abrasive qualities, pressure and temperature
of the liquid being pumped, this section is intended
only to provide general recommendations and
practices for preventive maintenance. Regardless
of the application however, following a routine preventive maintenance schedule will help assure
trouble-free performance and long life from your
Gorman-Rupp pump. For specific questions concerning your application, contact your GormanRupp distributor or the Gorman-Rupp Company.
Record keeping is an essential component of a
good preventive maintenance program. Changes
in suction and discharge gauge readings (if so
equipped) between regularly scheduled inspections can indicate problems that can be corrected
before system damage or catastrophic failure occurs. The appearance of wearing parts should also
be documented at each inspection for comparison
as well. Also, if records indicate that a certain part
(such as the seal) fails at approximately the same
duty cycle, the part can be checked and replaced
before failure occurs, reducing unscheduled down
time.
For new applications, a first inspection of wearing
parts at 250 hours will give insight into the wear rate
for your particular application. Subsequent inspections should be performed at the intervals shown
on the chart below. Critical applications should be
inspected more frequently.

PUMP AND SEAL DISASSEMBLY
AND REASSEMBLY
Review all SAFETY information in Section A.
Follow the instructions on all tags, label and decals attached to the pump.
This pump requires little service due to its rugged,
minimum-maintenance design. However, if it becomes necessary to inspect or replace the wearing
parts, follow these instructions which are keyed to
the sectional views (see Figures 1 and 2) and the
accompanying parts lists.
As described on the following pages, this manual
will alert personnel to known procedures which require special attention, to those which could damage equipment, and to those which could be dangerous to personnel. However, this manual cannot
possibly anticipate and provide detailed precautions for every situation that might occur during
maintenance of the unit. Therefore, it is the responsibility of the owner/maintenance personnel to ensure that only safe, established maintenance pro-
cedures are used, and that any procedures not addressed in this manual are performed only after es-
tablishing that neither personal safety nor pump integrity are compromised by such practices.
Before attempting to service the pump, shut down
the engine and take precautions to ensure that it
will remain inoperative. Close all valves in the suction and discharge lines.
For engine disassembly and repair, consult the literature supplied with the engine, or contact your
local Honda engine representative.
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.
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.
Suction Check Valve Disassembly
(Figure 2)
Before attempting to service the pump, remove the
pump casing drain plug (23) and drain the pump.
Clean and reinstall the drain plug.
To service the suction check valve, remove the suction piping. Remove the nuts (36) securing the suction flange (34) to the pump casing (1). Pull the
check valve assembly (37) from the suction port.
If no further disassembly is required, see Suction
Check Valve Installation.
Back Cover Removal
Before attempting to open or service the
pump:
1. Familiarize yourself with this manual.
2. Shut down the engine and take
precautions to ensure that the
pump will remain inoperative.
3. Allow the pump to completely cool
if overheated.
(Figure 2)
The wear plate assembly (22) can be serviced after
the back cover assembly (29) has been removed.
Remove the wing nuts and flat washers (27 and 28)
securing the back cover to the casing. Pull the
back cover and assembled wear plate from the
pump casing. Remove the cover plate gasket (33)
and clean the mating surfaces.
Inspect the wear plate and if replacement is required, remove the hardware (24 and 25) securing
it to the back cover.

Pump Casing Removal
(Figure 2)
To service the impeller or seal assembly, disconnect the discharge piping. See Figure 1 and remove the hardware (12, 13 and 14) securing the
pump casing to the base (3).
Support the pump casing (1) using a suitable hoist
and sling, and remove the hardware (17 and 18)
securing the pump casing to the intermediate (15).
Separate the parts by pulling the casing straight
away from the intermediate. If shims have been
used under the mounting feet to level the pump
casing, tie and tag these shims for ease of reassembly.
Remove the casing o-ring (21). Clean the mating
surfaces of the intermediate and pump casing.
Impeller Removal
(Figure 2)
To loosen the impeller (2), tap the vanes of the impeller in a counterclockwise direction (when facing
the impeller) with a block of wood or a soft-faced
mallet. Unscrew the impeller and replace it if
cracked or badly worn. Use caution when removing the impeller; tension on the seal spring will be
released as the impeller is unscrewed.
Slide the impeller adjusting shims (4) off the impeller shaft. Tie and tag the shims or measure and record their thickness for ease of reassembly.
Seal Removal and Disassembly
(Figures 2 and 3)
Remove the spring centering washer (5) and seal
spring. Slide the shaft sleeve (6) and rotating portion of the seal off the shaft as an assembly. Lubricate the sleeve adjacent to the seal and work oil up
under the rubber bellows. Slide the rotating portion
of the seal off the shaft sleeve.
Remove the hardware (17 and 18) and carefully
slide the intermediate (15) and stationary portion of
the seal off the shaft as a unit. Use a suitably sized
dowel to press the stationary element out of the intermediate from the back side.
NOTE
The seal assembly may be removed without completely disassembling the pump by using a pair of
stiff wires with hooked ends to pull the seal stationary seat out of the intermediate.
If no further disassembly is required, see Seal
Reassembly and Installation.
Seal Reassembly and Installation
(Figures 2 and 3)
Clean the seal cavity and shaft with a cloth soaked
in fresh cleaning solvent.
Most cleaning solvents are toxic and
flammable. Use them only in a well ventilated area free from excessive heat,
sparks, and flame. Read and follow all
precautions printed on solvent containers.
The seal is not normally reused because wear patterns on the finished faces cannot be realigned
during reassembly. This could result in premature
failure. If necessary to reuse an old seal in an emergency, carefully wash all metallic parts in fresh
cleaning solvent and allow to dry thoroughly.
Handle the seal parts with extreme care to prevent
damage. Be careful not to contaminate precision
finished faces; even fingerprints on the faces can
shorten seal life. If necessary, clean the faces with a
non-oil based solvent and a clean, lint-free tissue.
Wipe lightly in a concentric pattern to avoid
scratching the faces.
Inspect the seal components for wear, scoring,
grooves, and other damage that might cause leakage. Clean and polish the shaft sleeve, or replace it
if there are nicks or cuts on either end. If any components are worn, replace the complete seal;
never mix old and new seal parts.
If a replacement seal is being used, remove it from
the container and inspect the precision finished
faces to ensure that they are free of any foreign
matter.

the stationary seat into the intermediate bore until
fully seated. A push tube cut from a length of plastic
pipe would aid this installation. The I.D. of the tube
should be approximately the same as the I.D. of the
seal spring.
Subassemble the rotating element into the retainer
and bellows. Apply a drop of light oil on the precision finished faces; never use grease. Use even
pressure to carefully press this subassembly onto
the sleeve (6) until the rotating element is just flush
with the chamfered end of the sleeve.
Slide the sleeve and assembled rotating portion of
the seal onto the shaft until the seal faces contact.
Continue to push the sleeve through the seal until it
seats squarely against the shaft shoulder.
Install the seal spring and spring centering washer.

Impeller Installation And Adjustment
(Figure 2)
Inspect the impeller and replace it if cracked or
badly worn. Install the same thickness of impeller
shims (4) as previously removed. Apply anti-seize
to the shaft threads and screw the impeller onto the
shaft until tight.
A clearance of .008 to .015 inch (0,20 to 0,38 mm)
between the impeller and the intermediate is necessary for maximum pump efficiency. Measure this
clearance and add or remove impeller shims until
this clearance is reached.
Pump Casing Installation
(Figure 2)
Be sure the wear plate does not scrape against the
impeller.
Secure the back cover assembly to the pump casing using the hardware (27 and 28). Do not over
tighten the wing nuts; they should be just tight
enough to ensure a good seal at the back cover
shoulder.
Suction Check Valve Installation
(Figure 2)
Inspect the check valve components and replace if
required.
Position the check valve assembly (37) in the suction port with the check valve plate (40) facing toward the inside of the pump casing. Install the suction flange (34) and secure with the nuts (36).
Check the operation of the check valve to ensure
proper seating and free movement.
Final Pump Assembly
Secure the pump casing (1) to the intermediate
with the hardware (17 and 18). Be careful not to
damage the O-ring.
See Figure 1 and secure the pump casing to the
base (3) with the hardware (12, 13 and 14). Be sure
to reinstall any leveling shims used under the
mounting feet of the pump casing.
Back Cover Installation
(Figure 2)
Inspect the wear plate (22) and replace it if badly
worn or grooved. Install the wear plate on the back
cover using the hardware (24 and 25).
Clean any scale or debris from the back cover
shoulder and pump casing which might prevent a
good seal.
NOTE
Apply a film of ‘Never-Seez’ or equivalent compound on the back cover shoulder or any surface
which contacts the pump casing to ease future disassembly and to reduce rust and scale build up.
(Figure 1)
Be sure the pump and engine are securely
mounted to the base.
Install the suction and discharge lines and open all
valves. Make certain that all piping connections are
tight, properly supported and secure.
Be sure the engine has been properly lubricated,
see LUBRICATION.
Remove the fill plug assembly (7). Fill the pump
casing with clean liquid. Reinstall the fill plug and
tighten it.
Refer to OPERATION, Section C, before putting
the pump back into service.
