GENERAL INFORMATION
APPLICATION
The Multiquip QP3Ti Trash Pump is designed to be used
for dewatering applications. Both the suction and discharge
ports on the QP3Ti 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).
This Wet Primed pump requires that the pump casing
is first filled with water to assist with initial self-priming
operations. Once a partial vacuum is created within the
unit, the reduced atmospheric pressure allows water to
flow through the suction line and the centrifugal force of
the impeller/volute assembly permits water to be expelled
from the discharge ports.
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 8.6 horsepower air cooled
4-stroke, single cylinder HONDA iGX270 gasoline engine
that incorporates a low “Oil Alert Feature.”
OIL ALERT FEATURE
In the event of low oil or no oil, the HONDA iGX270 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
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 4 shows suction lift at various elevations.
Table 5 shows percentage drops in performance as
elevation increases.

Page 15
PUMP COMPONENTS
Figure 3 shows key component areas of the QP3Ti.
1. Pump — The QP3Ti offers a revolutionary choice for a
compact trash pumping system. It is the first gasolinepowered, compact, pipe-framed, centrifugal pump to
provide unattended operations, automatic no prime
shutdown, and easy manual dial water flow control.
Supported by the industry recognized QPT3 pump
end, this truly unique pump supports the watering/
dewatering jobs associated with: excavations, flood
waters, manholes, sewage bypass, barge cleaning,
foundations, and water transfer.
2. Fill Cap — Prior to operation, the pump casing MUST
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 Ports — The pump is equipped with left
and right side discharge ports. These ports are 3” male
NPT thread and can accommodate discharge hose or
pipe. Quick disconnect (Cam & Groove lock) hoses
can be fitted onto the discharge ports with an optional
coupler (A300A).
4. Discharge Hose — This pump is fitted with 3” male
NPT thread discharge ports and can accommodate
either threaded discharge hose or pipe. Quick
disconnect (Cam & Groove lock) hoses can be fitted
onto the discharge ports with an optional coupler
(A300A). Make sure hoses lay flat and are not kinked.
Contact MQ Sales Department for ordering information.
5. Suction Port — This pump is fitted with a 3” male
NPT thread suction port and can accommodate either
a threaded or quick disconnect (Cam & Groove lock)
hose. For quick disconnect connections, an optional
coupler (A300A) is necessary. Contact MQ Parts
Department for ordering assistance.
6. Suction Hose — Use only recommended suction
hoses. This pump is fitted with a 3” male NPT thread
suction port and can accommodate threaded or quick
disconnect (Cam & Groove lock) suction hose. Cam
& Groove lock hose can be fitted onto the suction
port with an optional coupler (A300A). Make sure
the suction hose is not kinked. Contact MQ Sales
Department for ordering information.
7. Clean-out Cover — When the pump is subjected to
applications where large quantity of debris is present,
it may be necessary to clean out the casing cavity of
large rocks and such that have not passed through the
pump. To open and gain access to the pump’s cleanout cavity, loosen the four locking knobs (item 9). Grip
the cover handles and twist counterclockwise. Once
the cover is clear of the four knob fasteners, pull the
cover out towards you.
8. Drain Plug — After usage, and for storage, remove
this plug and drain all water from the pump casing.
9. Locking Knobs — Turn both knobs counterclockwise
to release cover. Turn clockwise to secure clean-out
cover.
10. 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.
11. Wheel Kit — The QP3Ti comes with a wheel kit that
includes all necessary components and hardware. The
tires are 8” diameter, rugged terrain foam filled type.
12. Utility Box — Used to store float switches and can
also store tools necessary for pump use, setup, and
maintenance (optional).

DANGER
Motor fuels are highly flammable and can
be dangerous if mishandled. DO NOT
smoke while refueling. DO NOT attempt
to refuel the pump if the engine is hot!
or running.
Fuel Check
1. Remove the gasoline cap located on top of fuel tank.
Figure 6. Engine Oil Dipstick (Removal
QP3Ti TRASH PUMP • OPERATION AND PARTS MANUAL —REV. #1 (05/07/18) — PAGE 19
2. Visually inspect to see if the fuel level is low. If fuel is
low, replenish with unleaded fuel
3. When refueling, be sure to use a strainer for filtration.
DO NOT top-off fuel. Wipe up any spilled fuel
immediately!

SETUP
1. It is advantageous to place the pump as close as
possible to the water source (Figure 7) on a solid,
level operating surface. The most critical factor for
successful pump operations is not to exceed 25’ Total
Suction Lift (at sea level).
2. Ensure that the pump has the proper level of fuel and
engine oil.
3. Initially prime the pump by removing the fill cap (see
Figure 3) and filling the casing with water. If the pump
casing is not filled with water prior to operations, it will
not be able to start the pumping process and you risk
overheating the mechanical seal assembly.
4. Attach the proper suction and discharge hoses to the
pump ports. Ensure that the hose O-rings are in place,
and that hose do not show any cracks, gouges, or
holes. The hoses should not be kinked, and must be
secured tightly to their respective ports.
5. A proper suction hose is commonly reinforced with rigid
PVC helix and is specifically designed to safeguard
against collapsing during pumping operations. It is
essential that the pump utilize a suction hose with the
same diameter as the suction port.
6. Ensure that the strainer is placed on the end of the
suction hose, and that the hose is placed in the water
source in such a manner as not to bury the strainer
into sand or silt.
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.
7. The discharge side may utilize proper discharge hoses,
PVC pipe, or concrete pipe.
8. Check that discharge hoses lay flat and as straight as
possible. Remove any sharp bends or kinks from the
hose so the water flow cannot be blocked.
9. Once the engine is started; and depending on the
application set-up, the priming process will take a few
moments before water begins to flow.
10. The performance of the pump (Flow, Head, Water
Velocity, and Pressure) is dependent on the many
factors that surround the application. These factors
include, but are not limited to: operating altitude, suction
lift, discharge and suction hose diameter and length,
overall friction loss coefficients, the specify gravity of
the fluid to be pumped, the fluid temperature, and total
discharge head.

OPERATION
AUTO/STANDBY MODE
In the automatic mode:
Engine senses and adjusts RPMs automatically to match
the application's load and speed requirements.
Engine keeps running at higher RPM right after start
which makes speedy pump priming. It then goes back
automatically to normal RPM, in 15 seconds after start
for smooth flow discharging.
Engine turns off automatically one minute after water is
fully pumped, even if unattended, which prevents NoLoad running and useless fuel consumption.
1. Turn the DRAIN/FILL switch to the OFF position
(Figure 13).

MAINTENANCE (PUMP)
PUMP VACUUM TEST
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.
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 17, 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 17) 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.
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.
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.
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.
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.
NOTICE
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.
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.
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. See Components section, Clean-out Cover, for pump
cleaning procedure.
3. Clean and remove dirt, debris from pump casing.
Inspect impeller and volute for wear. Replace any
damaged or worn parts.
CAUTION
The impeller may develop sharp edges. Use extreme
care when cleaning around the impeller to prevent
being cut..

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.
STORAGE
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.
