GENERAL INFORMATION  
ground in a level position.  
APPLICATION  
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.  
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).  
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.  
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.  
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.  
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.  
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.  
Table 3. Suction Lift at Various Elevations  
Altitude  
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.

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  
Table 4 shows percentage drops in performance as  
elevation increases.  
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.

SETUP  
1. Place pump as near to water as possible, on a firm  
flat, level surface.  
NOTICE  
Suction and discharge hoses are available from  
Multiquip. Contact your nearest dealer for more  
information.  
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.  
7. The discharge hose is usually a collapsible  
(thin-walled) hose, however if a thin-walled discharge  
hose is not available, a rigid suction hose can be  
substituted in its place.  
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.  
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.  
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.  
CAUTION  
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.  
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.

OPERATION  
4. Place the choke lever (See Figure 10) in the OPEN  
position if starting a warm engine or the temperature  
is warm.  
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.  
STARTING THE ENGINE  
1. Place the engine fuel valve lever (See Figure 7) to the  
ON position.  
Figure 10. Engine Choke Lever (Open)  
5. Place the engine ON/OFF switch (See Figure 11) in

OPERATION  
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 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.  
Figure 15. Throttle Lever (Idle)  
2. After the engine cools, turn the engine ON/OFF switch  
to the OFF position (See Figure 15).  
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 16. Engine ON/OFF Switch (OFF)  
Figure 14. Throttle Lever (Run)  
WARNING  
3. Place the fuel shut-off lever (See Figure 16) in the  
OFF position  
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.  
Figure 17. Fuel Valve Lever (OFF)  
Emergency Shutdown  
CAUTION  
1. Move the throttle lever quickly to the IDLE position, and  
place the engine ON/OFF switch in the OFF position.  
ALWAYS run engine at full speed while pumping.

MAINTENANCE (PUMP)  
PUMP VACUUM TEST  
ADJUSTING IMPELLER CLEARANCE  
CAUTION  
1. If it is necessary to replace impeller or volute, be sure  
clearance between impeller and volute is adjusted  
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.  
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.  
To perform the pump vacuum test do the following:  
3. Check clearance between impeller and insert by slowly  
pulling starter rope to turn impeller.  
1. Remove the pump fill cap (See Figure 3), and fill the  
pump with water.  
NOTICE  
2. Start the engine as outlined in the initial start-up  
section, and wait for the pump to begin pumping.  
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.  
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 PumpVacuumTester (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.  
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.  
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.  
PUMP CLEANING  
After pumping water containing large amounts of dirt and  
debris, perform the following:  
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.  
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.  
NOTICE  
3. Clean and remove dirt, debris from pump casing.  
Inspect impeller and volute for wear. Replace any  
damaged or worn parts.  
25 in. Hg (inches of mercury) translates into 25 feet of  
lift at sea level.  
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.  
CAUTION  
The impeller may develop sharp edges. Use extreme  
care when cleaning around the impeller to prevent  
being cut..  
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.

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.  
This will prevent excessive corrosion and also keep the  
mechanical seal lubricated.
