ground in a level position.
NEVER place the pump on soft soil. The suction hose or
pipe connection should always be checked for tightness
and leaks. A small suction leak in the hose or fittings could
prevent the pump from priming.
Elevation
Higher elevations will effect the performance of the pump.
Due to less atmospheric pressure at higher altitudes,
pumps DO NOT have the priming ability that they have at
sea level. This is due to the “thinner air” or lack of oxygen
at higher altitudes.
A general rule of thumb is that for every 1,000 feet of
elevation above sea level a pump will lose one foot of
priming ability.
For example, in Flagstaff, Arizona where the elevation is
approximately 7,000 feet, the pump would have a suction
lift of only 18 feet rather than the 25 feet at sea level.
Table 3 shows suction lift at various elevations.

GENERAL INFORMATION
APPLICATION
The Multiquip QP3TH Trash Pump is designed to be
used for dewatering applications. Both the suction and
discharge ports on the QP3TH trash pump use a 3-inch
diameter opening,which allows the pump to pump at a rate
of approximately 396 gallons/minute (gpm) or 1,500 liters/
minute (lpm).
Trash pumps are designed to purge air from thesuction
line and create a partial vacuum in the pump body. The
reduced atmospheric pressure inside the pump allows
water to flow through the suction line and into the pump
body. The centrifugal force created by the rotating impeller
pressurizes the water and expels it from the pump.
TRASH PUMP
Trash pumps derive their name from their ability to handle
a greater amount of debris and solids than standard
centrifugal pumps. These pumps generally handle solids
up to 1/2 the size of the discharge opening making them
less likely to clog. Also trash pumps are capable of handling
water with 25% solids by weight.
The advantage of using a trash pump is that it can be
quickly and easily disassembled in the field "without tools"
and easily cleaned when clogged.
POWER PLANT
This trash pump is powered by a 7.1 horsepower air cooled
4-stroke, single cylinder HONDA GX240 gasoline engine
that incorporates a low “Oil Alert Feature.”
OIL ALERT FEATURE
In the event of low oil or no oil, the HONDA GX240 engine
has a built-in oil alarm engine shut-down feature. In the
event the oil level is low the engine will automatically
shutdown.
SUCTION LIFT
This pump is intended to be used for dewatering applications
and is capable of suction lifts up to 25 feet at sea level. For
optimal suction lift performance keep the suction hose or
line as short as possible. In general always place the pump
as close to the water as possible.
PUMP SUPPORT
The pump should always be placed on solid stationary
PAGE 14 — QP3TH TRASH PUMP • OPERATION AND PARTS MANUAL — REV. #8 (01/29/14)
PUMP COMPONENTS
Figure 3 shows a typical application using the QP3TH centrifugal pump. Please note that this pump is intended for the
removal of clean water.
Figure 3. QP3TH Pump Application
1. Pump — The model QP3TH is a 3-inch trash pump
aused in general dewatering applications.Typical
dewatering applications consist of manholes, septic
tanks, fast and slow seepage ditch water, silt water,
mud water and muck water.
2. Fill Cap — Prior to operation, the pump casing should
be filled with water. Remove this cap to add water to
the pump. After the initial prime, a sufficient amount of
water will be retained in the casing so that the operator
will not need to re-prime later.
3. Discharge Port — Connect a 3-inch discharge hose
to this port.
4. Worm Clamp — Used to secure the hose to the inlet
and outlet ports on the pump. Use two clamps to secure
the hose on the inlet side of the pump.
5. Discharge Hose — Connect a flexible rubber
hose to the discharge port on the pump. Make sure
that the hose lays flat and is not kinked. Use only
recommended type discharge hose. Contact Multiquip
Parts Department for ordering information.
6. Suction Port — Connect a 3-inch inlet hose to this port
Use two worm clamps to secure the hose.
7. Suction Hose — Connect this flexible rubber hose to
the suction port on the pump. Make sure that the hose
lays flat and is not kinked. Use only recommended type
suction hose. Contact Multiquip parts department for
ordering information.
8. Clean-out Cover Handles — To gain access to the
pump's clean-out area, grip both handles, then pull to
remove cover. Make sure both locking knobs have been
released before attempting to remove clean-out cover.
9. Drain Plug — Remove this plug to drain water from
the pump.

11. Locking Knobs — Turn both knobs clockwise to
secure clean-out cover, turn counter-clockwise to
release cover.
12. Strainer — Always attach a strainer to bottom side of
the suction hose to prevent large objects and debris
from entering the pump. Strainer should be positioned
so that it will remain completely under water. Running
the pump with the strainer above water for long periods
can damage pump.
QP3TH TRASH PUMP • OPERATION AND PARTS MANUAL — REV. #8 (01/29/14) — PAGE 15
6. Choke Lever — Used in the starting of a cold engine,
or in cold weather conditions. The choke enriches the
fuel mixture.
7. Air Cleaner — Prevents dirt and other debris from
entering the fuel system. Remove wing-nut on top of
air filter cannister to gain access to filter element.
8. Spark Plug — Provides spark to the ignition system.
Set spark plug gap to 0.6 - 0.7 mm (0.028 - 0.031 inch).
Clean spark plug once a week.
9. Muffler — Used to reduce noise and emissions.
10. Fuel Tank — Holds unleaded gasoline. For additional
information refer to engine owner's manual.
NOTICE
Operating the engine without an air filter, with a
damaged air filter, or a filter in need of replacement
will allow dirt to enter the engine, causing rapid engine
wear.
WARNING
Engine components can generate
extreme heat. To prevent burns,
DO NOT touch these areas while the
engine is running or immediately after
operating. NEVER operate the engine
with the muffler removed.

hose is not available, a rigid suction hose can be
substituted in its place.
8. Make sure the suction strainer (See Figure 3) is
clean and securely attached to the water end of the
suction hose. The strainer is designed to protect the
pump by preventing large objects from being pulled in
to the pump.
1. Place pump as near to water as possible, on a firm
flat, level surface.
2. To prime pump, remove fill cap (See Figure 3) and fill
pump casing with water. If the pump casing is not filled
with water before starting, it will not begin pumping.
3. Attach suction and discharge hoses to the pump. Check
that all hoses are securely attached to the pump. Make
certain suction hose (See Figure 3) does not have
any air leakage. Tighten hose clamps and couplings
as required.
4. It is recommended that 2 clamps be used when
securing the suction hose to the inlet side (suction)
of the pump.
5. Remember suction hoses must be rigid enough not to
collapse when the pump is in operation.
6. Check that the discharge hose (See Figure 3) is not
restricted. Place hose so that it lays as straight as it is
possible on the ground. Remove any twists or sharp
bends from hose which may block the flow of water.
NOTICE
Suction and discharge hoses are available from
Multiquip. Contact your nearest dealer for more
information.
CAUTION
The strainer should be positioned so it will remain
completely under water. Running the pump with the
strainer above water for long periods can damage the
pump.
SETUP
PAGE 18 — QP3TH TRASH PUMP • OPERATION AND PARTS MANUAL — REV. #8 (01/29/14)
OPERATION
STARTING THE ENGINE
1. Place the engine fuel valve lever (See Figure 7) to the
ON position.
Figure 7. Engine Fuel Valve Lever (ON Position)
2. Move the throttle lever (See Figure 8) away from the
slow position, about 1/3 of the way toward the fast
position.
Figure 8. Throttle Lever (1/3 Start Position
3. Place the choke lever (See Figure 9) in the CLOSED
position if starting a cold engine.
Figure 9. Engine Choke Lever (Closed)
CAUTION
DO NOT attempt to start the engine unless the pump
has previously been primed with water. Severe pump
damage will occur if pump has not been primed.
4. Place the choke lever (See Figure 10) in the OPEN
position if starting a warm engine or the temperature
is warm.
Figure 10. Engine Choke Lever (Open)
5. Place the engine ON/OFF switch (See Figure 11) in
the ON position.
Figure 11. Engine ON/OFF Switch (ON Position)
6. Grasp the starter grip (See Figure 12) and slowly pull
it out. The resistance becomes the hardest at a certain
position, corresponding to the compression point. Pull
the starter grip briskly and smoothly for starting.
Figure 12. Starter Grip
7. If the engine has started and the choke lever was
moved to the CLOSED position to start the engine,
gradually move the choke lever to the OPEN position
(Figure 13) as the engine warms up. If the engine has
not started repeat steps 1 through 6.
QP3TH TRASH PUMP • OPERATION AND PARTS MANUAL — REV. #8 (01/29/14) — PAGE 19
OPERATION
Figure 13. Choke Lever (Open)
8. Before the pump is placed in to operation, run the
engine for several minutes. Check for fuel leaks, and
noises that would associate with a lose component.
9. To begin pumping, place the throttle lever (See
Figure 13) in the RUN position. If water is not flowing
out of the discharge port, turn off the engine and check
for and clear any obstructions within the suction hose.
Figure 14. Throttle Lever (Run)
WARNING
Water must always be flowing through the pump casing
while the engine is running. Loss of flow may be the
result of a loss of prime, restricted water flow or a dead-
head situation. Please note that in such a condition,
water in the pump can reach temperatures of 150-200°F
in 15 to 20 minutes. This can cause serious burns if
this hot water comes into contact with unprotected skin.
Before touching or opening the fill plug or drain plug,
first turn off the engine and allow the pump casing to
cool to the touch, and then open the pump carefully.
Be cautious of any built up water pressure.
CAUTION
ALWAYS run engine at full speed while pumping.
STOPPING THE ENGINE
Normal Shutdown
1. Move the throttle lever to the IDLE position
(See Figure 14) and run the engine for three minutes
at low speed.
Figure 15. Throttle Lever (Idle)
2. After the engine cools, turn the engine ON/OFF switch
to the OFF position (See Figure 15).
Figure 16. Engine ON/OFF Switch (OFF)
3. Place the fuel shut-off lever (See Figure 16) in the
OFF position
Figure 17. Fuel Valve Lever (OFF)
Emergency Shutdown
1. Move the throttle lever quickly to the IDLE position, and
place the engine ON/OFF switch in the OFF position.
PAGE 20 — QP3TH TRASH PUMP • OPERATION AND PARTS MANUAL — REV. #8 (01/29/14)
PUMP VACUUM TEST
To perform the pump vacuum test do the following:
1. Remove the pump fill cap (See Figure 3), and fill the
pump with water.
2. Start the engine as outlined in the initial start-up
section, and wait for the pump to begin pumping.
3. As shown in Figure 18, place a water hose inside
the discharge opening of the pump, and turn on the
water. This flow of water into the discharge opening
will prevent the pump from running dry.
4. Place the Pump Vacuum Tester (P/N 7000030) over the
pump suction (inlet) opening (See Figure 18) with the
vacuum gauge facing upwards. It may be necessary
to apply a small amount of water around the rubber
seal of the vacuum tester to make a good suction fit.
5. Check and make sure that there are no air leaks
between the vacuum tester and the inlet port on the
pump. If air leaks are present reseat vacuum tester.
6. Run the pump for a few minutes while monitoring the
vacuum gauge. If the gauge indicates a reading
between -25 and -20 in. Hg. (inches of mercury) then
it can be assumed that the pump is working correctly.
7. If the vacuum tester gauge indicates a reading below
-20 in. Hg, it can then be assumed that the pump is
not functioning correctly, and corrective action needs
to be taken.
8. To test the flapper valve, shutdown the engine. The
vacuum tester should remain attached to the pump
suction inlet port by vacuum. This indicates the pump's
flapper valve is seating properly to hold water in the
suction hose when the engine is stopped. This prevents
backflow and allows for faster priming when the engine
is restarted.
NOTICE
25 in. Hg (inches of mercury) translates into 25 feet of
lift at sea level.
MAINTENANCE (PUMP)
CAUTION
DO NOT attempt to start the engine unless the pump
has previously been primed with water. Severe pump
damage will occur if pump has not been primed.
ADJUSTING IMPELLER CLEARANCE
1. If it is necessary to replace impeller or volute, be sure
clearance between impeller and volute is adjusted
2. The impeller should be as close to the volute as
possible without rubbing against it. Clearance is
adjusted by adding or removing shims from behind
the impeller.
3. Check clearance between impeller and insert by slowly
pulling starter rope to turn impeller.
4. Check the impeller every six months for wear, and for
clearance between the impeller face and the volute.
Also check the shaft seal for wear, as well as the shaft
sleeve.
PUMP CLEANING
After pumping water containing large amounts of dirt and
debris, perform the following:
1. Remove the drain plug from the pump housing
(Figure 3) and drain any water left in the pump.
2. Loosen the two locking hand knobs (turn
counterclockwise) and remove clean-out cover.
3. Clean and remove dirt, debris from pump casing.
Inspect impeller and volute for wear. Replace any
damaged or worn parts.
NOTICE
It is important not to remove too many shims or the
clearance between the impeller and volute will become
too wide and pump performance will be reduced.
Remember as the impeller wear down, additional shims
may be required to maintain the clearance between the
impeller and insert.
CAUTION
The impeller may develop sharp edges. Use extreme
care when cleaning around the impeller to prevent
being cut..

STORAGE
PUMP STORAGE
For storage of the pump for over 30 days, the following is
required:
Drain the fuel tank completely.
Run the engine until the fuel is completely consumed.
Completely drain used oil from the engine crankcase
and fill with fresh clean oil, then follow the procedures
described in the engine manual for engine storage.
Remove the drain plug from the pump and drain out any
water from left in the housing.
Remove the pump cover and clean inside of pump
housing. Coat inside of pump housing with a light film
of oil to reduce corrosion. A spray can of oil works well
for this application.
Cover suction and discharge ports with duct tape to
prevent any foreign matter from falling into pump.
Cover pump and engine with plastic covering or
equivalent and store in a clean, dry place.
To protect the water cooled-seals, place one-half pint
of lubricating oil (new or used) through the discharge
opening on the pump and crank the engine several times.
