Description and Specifications
This Self-Priming – Centrifugal Pump is designed to
pump muddy water with minute quantities of suspended
solids. When pumping water, the pumps are self priming
on static suction lifts up to 25 feet (7.6 meters), while
with liquids which foam or foam emulsions, the static
suction lift is reduced to 10 feet (3 meters). A cast iron
impeller with solids handling capabilities is used.
THIS PUMP IS DESIGNED TO PUMP
WATER. NEVER USE THIS SELF
PRIMING PUMP TO PUMP FUEL,
FLAMMABLE, CORROSIVE OR
COMBUSTIBLE LIQUIDS. PUMPING
ABRASIVE LIQUIDS IS ALSO HAZARDOUS. IF IN DOUBT, CONSULT
FACTORY FOR PROPER USE AND
APPLICATION.
1. Important Safety Precautions
BEFORE USING YOUR SELF-PRIMING – CENTRIFUGAL PUMP, READ
AND FOLLOW THESE SAFETY PRECAUTIONS.
1. Never use these pumps for pumping flammable liq-
uids such as diesel or gasoline.
2. Before starting the pumps, follow all of the instruc-
tions in this manual and any supplemental instructions supplied with the pump.
3. Any person operating this pump and its power unit
should be fully aware of its safe operation before they
start using it.
4. Never operate an engine driven unit in an explosive
atmosphere, near combustible materials, or where
insufficient ventilation exists unless specific provisions have been made regarding the power unit so
as to prevent possible injury and damage. Be certain
the power unit is safe for the area in which it is to be
operated.
5. Always be sure the unit is on a secure footing. Keep
the immediate pump 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.
6. Never operate the unit with any guards removed.
7. Do not overtighten the drain or filler plugs.Excessive
force may damage the threads or the pump body.
8. With engine driven pumps: A) Observe all safety pre-
cautions for the handling of fuel. B) Never refuel the
engine while running. C) Never refuel a hot engine.
D) Run engine only in well ventilated areas.
9. Before working on this pump make sure the power
unit cannot inadvertently be started.
10. Be sure the power unit, pump, wiring and piping
installations are suitable for the liquid being pumped
and comply with all applicable codes and regulations.
11. Use at least 12" (300 mm) of flexible hose to make
plumbing connections to the pump body. 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.
12. Do not run the pump dry. Always fill the pump body
with water before starting. It is not necessary to drain
the pump body after use, unless there is danger of
freezing, settling of solids, or crystallization.
13. Do not subject pump to extreme conditions of acidity
or basicity. Consult factory for specific recommendations concerning chemicals and temperatures.
14. Only use original spare parts.
2. Before Starting
2.1 A suction strainer should be attached to the suction
hose or pipe. It is provided with holes or slots small
enough to prevent big stones, etc., from working
through and damaging the pump. Keep the strainer
clean. If possible, suspend the strainer to keep it from
working into the sediment. Or,
A) Prepare a bed of stones on which to rest the strainer.
B) Tie the strainer inside a basket or pail.
2.2 Fill the engine crankcase and air cleaner with oil as
specified in the Engine Manual.
2.3 FUEL: Regular gasoline (leaded or unleaded) which
can be mixed to the extent of 10% by volume with
ethanol. DO NOT use methanol.
2.4 Fill the pump with water through the priming port
on the top of the pump. Remember the pump is selfpriming only when the pump is filled.
2.5 Make certain that all hose and pipe connections are
airtight.
IMPORTANT: An air leak in the suction line may
prevent priming and will reduce the
capacity of the pump. Use sealant on all
threaded connections.

2.6 Place the pump on level, firm foundation, putting it
as near as possible to the level of the liquid which is
to be pumped, but never higher than 25 feet (7.5 meters). Keep all lines straight and as short as possible.
Avoid sharp bends.
3. Operating Instructions
3.1 STARTING – See Engine Manual
3.2 PRIMING TIME – with a suction lift from 5 to 10
feet (1.5 to 3 meters)*, the pump should discharge
liquid in less than a minute; a suction lift of 25
feet (7.6 meters)*, requires less than 2 minutes. To
further reduce priming time the engine speed may
be increased, after the engine is properly broken in.
If pumping does not start within this time, shut off
engine and check to find the difficulty (see Troubleshooting).
3.3 CONTROL – On high suction lifts, a higher engine
speed is necessary. On shallow lifts or when there is
but a little liquid to pump, save fuel and engine life
by reducing the engine speed. (See Engine Manual)
3.4 CHECK VALVE – If discharge line runs vertically
more than 30 feet (9 meters), it is advisable to install
a check valve in the discharge line near the pump to
stop destructive water hammer when pump is shut
down. If this is done, it may be necessary to vent the
top of the pump so that air can be expelled during
automatic re-priming. This air bleed may be accomplished by providing a ¼" (.5 cm) line from the top
of the pump back to the liquid source. We will not
assume any responsibility for damage to the pump if
no check valve is used in the discharge line. Properly
fueled and lubricated, your pump will run without
attention.
3.5 If flexible hose must be laid across a roadway, protect
it with planking. Instantaneous shutoff pressure applied when a vehicle runs over an unprotected hose
will cause “hydraulic shock”, which may damage the
casing or seals.
3.6 Drain the pump body whenever there is danger of
freezing.
3.7 Always flush 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.

4. Troubleshooting
A) PUMP FAILS TO PRIME
1. Priming chamber empty or not sufficiently full.
2. Wrong direction of rotation.
3. Air leaks through the suction line joints (loose screws or
broken hoses).
4. Quick coupling gaskets broken or not well mounted.
5. Hose clamps loose or broken (tighten or replace).
6. Liquid in priming chamber overheated (fill with
cold liquid).
7. Delivery line under pressure (see Operating Instruc-
tions).
8. Rotation Speed too slow (increase speed).
9. Worn or broken impeller, worn or damaged volute
(replace as required).
10. Air leaks through damaged mechanical seal (replace
the seal).
B) LOW CAPACITY
1. Suction strainer clogged (clean).
2. Suction or delivery line obstructed (remove obstruction).
3. High friction losses in the suction line (eliminate
unnecessary curves, restrictions or valves).
4. Suction lift too high (set up the pump as near as possible
to the water level).
5. Rotation speed too low (increase speed).
6. Impeller clogged (remove obstruction).
