I. SAFETY PRECAUTIONS
WARNING:
 1. Neverusethesepumpsfor pumping ammableliquidssuch
as gasoline. AN EXPLOSION AND SERIOUS INJURY MAY
RESULT IF THIS WARNING IS IGNORED.
 2. In pumping corrosive materials, extreme caution should be
exercised.  Provide safety guards, ventilation, and drains to
protect people and property in case of a leak in the pump.
Handling instructions from the manufacturer(s) of the liquids
being pumped should be closely followed.
3. Before starting the pump, follow all of the instructions in this
manual and any supplemental instructions supplied with the
pump.
4. Any person operating this pump and its power unit should be
fully aware of its safe operation before they start using it.
 5. Neveroperateanengine-drivenunitinanexplosiveatmosphere,
nearcombustiblematerials,orwhereinsufcientventilationex-
istsunlessspecicprovisionshavebeenmaderegardingthe
power unit so as to prevent possible injury and damage. Be
certain any other power unit is safe for the area in which it is to
be operated.
6. Always be sure that the unit is on a secure footing and keep the
immediate pump and power unit area free of all unauthorized
personnel. If the pump is sitting beside a pit, be sure it is well
anchored so that it does not fall in.
7. Never operate the unit with any guards removed.
8. With engine-driven pumps:
a. Observe all safety precautions for the handling of fuel.
b. Never refuel the engine while running, and care
shouldbeexercisedsothatnofuelisspilledonahotengine.
Always allow engine to cool at least two minutes before refu-
eling.
9. Before working on this pump make sure that the power unit
cannot inadvertently be started.
10. Be sure that the power unit, pump, wiring and piping installa-
tions are suitable for the liquid being pumped, and comply with
all applicable codes and regulations.
11. Donotusetorchesorapplyreoramestothispumpsforany
reason.
12. This pump must not be subjected to more than 65 pounds per
square inch internal pressure. The pump itself, normally can-
not develop more than 55 pounds per square inch pressure.
The pump most not be used under any of the following unusual
conditionswhichcanresultinexcessivepressuresbeingde-
veloped:
  A. Pumpshaftspeedover3600RPM.
B. Quick closing valves in discharge line or any other device
which may introduce hydraulic shock into the system.
C. Possible sudden obstruction of discharge line such as
vehicle driving over hose.
  D. High positive suction pressures (such as with a ooded
suction) which would increase the total system pressure to 65
PSI or above.
  E. Donotpumpliquidswithspecicgravitiesexceedingthe
following values:
Maximum
    Impeller* SpecicGravity**
Number at 3600 RPM
667 2.1
707 1.6
709 1.6
975 2.1
*The impeller curve letter appears in the model number on the pump
label.Itisthefthdigitofthemodelnumber.
**Thespecicgravityistherationoftheweightoftheliquidtobe
pumped to the weight of an equal volume of water. Water has
aspecicgravityof1.0.Therefore,aliquidwhichisheavier
thanwaterhasaspecicgravitygreaterthan1.0.
13. Donotovertightenthedrainplug.Handtightenonly.Excessive
force may damage the threads or the pump body. Do not use
a metal plug.
14. Useatleastonefootofexiblehosetomakeplumbingconnec-
tions to the pump. Rigid piping may put stresses on the pump,
causing damage. If rigid piping must be used, properly support
it so as to eliminate stresses on the pump.

PO-1775F
15. Donottighteninletanddischargettingsmorethanone
turn beyond hand tight. Excessive force will damage the
pumporttings. Useteonsealingtape onallthreaded
ttings.
16. Long suction and discharge hoses or pipes must be supported
sothattheweightofthehosesorpipeslledwithliquiddoes
not damage the pump or tip it over.
17. Use replacements parts supplied by the manufacturer only.
18. Do not run the pump dry.Alwaysllthesystemwithliquidto
be pumped before starting the pump. The system consists of
thepumpandsuctionline.Ifthepumphasa‘oodedsuction’
(the liquid to be pumped is above the pump itself) then the pump
andsuctionlinewillbelledbytheliquidtobepumped.Ifthe
pumpisona‘suctionlift’(theliquidtobepumpedisbelowthe
pump) then it will be necessary to install a foot valve at the end
of the suction line so that the foot valve is completely immersed
in the liquid to be pumped. In the case of a suction lift situation,
itisnecessarytollthesuctionlineandthepump(referredto
as the system) before starting the pump. A non-self-priming
centrifugal pump can only pump if the system is full of liquid
and the pump encounters no air. It is not necessary to drain the
pump after use, unless there is danger of freezing, settling of
solids, or crystallization.
19. Donotsubjectpumptoextremeconditionsofacidityorbasic-
ity. Consult factory for specic recommendations concerning
chemicals and temperatures.
20. Do not operate pump with closed discharge valve for any lengthy
period of time. Liquid in pump will overheat. If necessary to
reducepumpowwithoutloweringthespeed(RPM),avalve
maybeusedinthedischargelinetothrottletheow.
21. Do not restrict the suction line or try to throttle the pump on
the suction side because cavitation may result. Cavitation is
evidenced by noisy pump operation and pitting of pump parts.

PO-1775F III. PUMP OPERATING INSTRUCTIONS
1. Fill the system with liquid before starting. Do not run the pump
dry; damage to the mechanical shaft seal may result. There are
no points on the pump which need lubrication. The mechani-
cal shaft seal is self lubricating, and designed to handle clean
liquids.
 2. Makecertainallpipeorhoseconnectionsareairtight.Anairleak
inthesuctionlineunder‘oodedsuction’operationswillreduce
ow.Anairleakinthesuctionlineona‘suctionlift’installation
will prevent operation.
3. Always place the pump as close to the liquid to be pumped as
possible. Keep all lines as short and straight as possible. Avoid
sharp bends in hoses. Keep the pump on a level foundation.
 4. Ifexiblehosemustbelaidacrossaroadway,protectitwith
planking. Instantaneous shut off pressures applied when a
vehicle runs across an unprotected hose will cause “hydraulic
shock”. This shock can damage the pump and/or damage the
hose. See Figure #1.
5. When pumping dirty water or other liquids which may contain
solids,alwaysuseapumpstrainerspeciedbythemanufac-
turerontheendofthesuctionline.Inthecaseof‘suctionlift’
conditions, the strainer will have to be a combination foot valve
and strainer.
6. Drain the pump whenever there is danger of freezing.
7. Always use rubber feet under portable pump when operating
on a hard surface. This will prevent damage to the pump and
power unit.
 8. Alwaysushoutthepumpattheendofoperationiftheliquid
being pumped may leave a solid or sticky residue in the pump.
If this is not done, damage to the pump may result.
IV. PUMP TROUBLE SHOOTING AND REPAIR
PROBLEM
 1. Pumpdoesnotproduceoworhasinsufcientow.
POSSIBLE CAUSE
 a. Pump and suction line not completely lled. See Section I,
paragraph #18.
b. Leak in suction line.
c. Foot valve and strainer not completely immersed.
 d. Mechanicalshaftsealleakingair.
e. Impeller rotation incorrect (impeller should rotate counterclock-
wise when viewing through suction end).
 f. Impellerspeed(RPM)toolow.
g. Worn impeller and/or volute. See Section V, paragraphs 4, 5,
and 6.
V. Pump Disassembly and Repair
NOTE: Pump may be disassembled and repaired using simple
“screwdrivermaintenance”.Seeexplodedviewdrawingatend
of manual for item numbers mentions.
 1. Removethesix¼”volutescrewsandnuts(items21&4)and
remove the volute (item 17).
2. Remove the large o-ring (item 7) from around the bracket (item
6).
3. Unscrew the impeller screw (item 16) and remove it along with
the small o-ring (item 8). Slide the impeller (item 16) and key
(item 27) off the shaft. (To facilitate removal of impeller, gently
force two screwdrivers 180° apart under the back of the impeller
and gently pry the impeller off the shaft).
NOTE: Impeller shims (item 30) may or may not have been used
on your pump. Check for these and save them for reuse.
4. One-half of the shaft seal (item 14) is in the impeller hub (item
15), and the other half (item 13) is mounted in the bracket (item
6) where the shaft protrudes. Only remove the impeller portion
of the seal and the bracket portion of the seal if you intend to
replace both seal elements with new parts. Always protect the
sealing surfaces from nicks, scratches and dirt.
5. Remove the four bracket screws (item 9) and the four small
o-rings (item 8), one on each screw. The bracket (item 6) may
now be removed. The bracket (stationary) portion of the shaft
seal (item 13) may now be pressed out from the backside of
the bracket. Use a round wooden plug 1-3/16” in diameter and
carefully press the seal out straight. If it is to be reused, carefully
check the face for nicks or scratches. If no damage is evident,
carefully store for reinstallation. Save the o-ring (item 11) which
surrounds the seal.
NOTE: If plugs (item 12) are installed over the bracket screw
heads (item 9), remove by screwing a volute screw (item 21)
into the plug and carefully pulling out. Be careful not to strip
the threads which the screw forms in the plug.
REASSEMBLY -READTHEFOLLOWINGINSTRUCTIONSBE-
FOREREASSEMBLY.
Reassembly involves putting the pump together in the reverse
order of the disassembly sequence described above.

PO-1775F
1. When installing a new seal, always replace both elements (items
13&14)andinstalltheo-ring(item11)aroundthebrackethalf
of the seal (item 13). Do not bear directly on the seal surface
when installing the bracket half. Use a piece of pipe that will bear
onlyonthemetalangeofthesealcase.Theimpellerhalfof
the seal (item 14) may be pressed in with the thumbs. Be sure
both seal halves are seated squarely with respect to the pump
shaft.
 2. Duringnalassemblyitisrecommendedthatthe5screwhead
o-rings (item 8) be replaced. Lubricate these with a vegetable
type oil only. (DO NOT use petroleum based oil).
3. Use a thread locking compound such as Loctite #242 on the
bracket screw (item 9) threads and on the impeller screw (item
16) threads.
4. The clearance between the impeller (item 15) vanes and the
volute (item 17) face should be about .015” to .025” for good
performance. This “front” clearance can be obtained by shim-
ming with the washer type shims (item 30) mentioned in step 3
of the disassembly instructions. Use the same shims which you
savedfromstep3.Installtheimpeller(item15)andrmlypress
on the impeller (hub only) while rotating the impeller 360°. If
scraping is heard, add shim or shims until scraping noise is not
heard.Installtheimpellerscrewando-ring(items16&8).Install
thevolute(item17)andthescrewsandnuts(items21&4).
Rotate the shaft while listening for scraping noise. If scraping is
heard, remove the volute and impeller and remove one washer
type shim. Repeat this procedure until no scraping is heard.
5. Check the impeller vanes for proper height. The following mea-
surements should be found when measuring the vane height at
the outside perimeter of the impeller (vane tip):

VI. SPECIAL INFORMATION
A. FLEXIBLE COUPLED PUMPS: COUPLING ALIGNMENT
  Measurethediameterofthepumpshaftandpowerunitshaft.
Choose the appropriate coupling for your pump and power unit.
(SeeexiblecouplingschargenumberVI-A).Propershaftand
coupling alignment reduces vibration and prevents premature
coupling failure. The following 8 steps help in obtaining proper
shaft alignment.
  1. Makesureyouusearigidbaseplatelargeenoughforthe
assembly of the pump and the drive unit. We offer kits, 58-0028
and 58-0016, for this purpose. (See base plate kits listed after

5. Compare measurements obtained from steps 3 and 4
and use spacer blocks for height adjustment to insure align-
ment of both shafts.
6. Place the coupling halves over each shaft, put the “spider”
between the two halves and couple the two halves together.
7. To assure parallel alignment (Figure 5) place a straight edge
along the side of both coupling halves in two different locations,
90° apart. The coupling is aligned when the straight edge rests
squarely on the sides of both coupling halves.

8. To avoid angular misalignment, insert a measuring device
(taper gauge or feeler gauge) between the coupling faces at four
locations 90° apart (See arrows in Figure 6) and measure the
gap at each of the four locations. For proper alignment all four
measurements should be equal. Reshimming may be required
to achieve this alignment.
