GENERAL INFORMATION
APPLICATION
The QP4TZ Trash Pump is designed to be used for
dewatering applications. Both the suction and discharge
ports on the trash pump use a 4-inch diameter opening,
which allows it to pump at a rate of approximately 526
gallons/minute (gpm) or 2,000 liters/minute (lpm).
Trash or self-priming pumps are designed to purge air from
the suction 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.
ENGINE
This trash pump is powered by a 9.9 horsepower, aircooled, HATZ 1B40 diesel engine.
TRASH PUMP
Trash pumps derive their name from their ability to handle
a greater amount of debris and solids than standard
centrifugal pumps. This pump generally handles 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.
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.
TRAILER
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 25 feet rather than the 18 feet at sea level. Table 4
shows suction lift at various elevations.

COMPONENTS (PUMP)
Figure 3 shows a typical application using the QP4TZ trash pump. Please note that this pump is intended for the removal
of clean water and water containing some debris and solids. Maximum size of solids should not exceed 1.5 inch (30 mm)
in diameter. DO NOT set strainer on bottom of water bed. Placing the strainer above the water bed will prevent the pump
from drawing in excessive amounts of sand and foreign debris.

Figure 3. QP4TZ Pump Application
1. Pump — The model QP4TZ is a 4-inch trash pump
used 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.
If the casing is dry or has insufficient water, the pump will
have difficulty in priming which could lead to premature
mechanical seal wear thus causing damage to the pump.
3. Discharge Port — Connect a 4-inch discharge hose
to either port (one of two ports).
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 this 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.

7. Suction Hose — Connect this flexible rubber hose to
the suction portion 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.
10. Clean-out Cover — Remove cover to gain access to
the clean-out area.
11. Locking Knobs — Turn both knobs clockwise to secure
clean-out cover, turn counterclockwise to release cover.
12. Strainer — Always attach a strainer to the 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.

DANGER
NEVER operate the pump in a confined
area or enclosed area structure that does
not provide ample free flow of air.
CAUTION
ALWAYS wear approved eye and hearing
protection before operating the pump.
BEFORE STARTING
1. Read safety instructions at the beginning of manual.
2. Clean the pump, removing dirt and dust, particularly
the engine cooling air inlet, carburetor and air cleaner.
3. Check the air filter for dirt and dust. If air filter is dirty,
replace air filter with a new one as required.
4. Check carburetor for external dirt and dust. Clean with
dry compressed air.
5. Check fastening nuts and bolts for tightness.
Engine Oil Check
1. To check the engine oil level, place the pump on secure
level ground with the engine stopped.
2. Remove the filler dipstick from the engine oil filler hole
(Figure 5) and wipe clean.
3. Insert and remove the dipstick without screwing it into
the filler neck. Check the oil level shown on the dipstick.

SETUP
BEFORE STARTING
1. Read safety instructions at the beginning of manual.
2. Move the trailer as near to the water as possible.
3. To prime pump, remove fill cap (Figure 3) and fill pump
casing with water. If the pump casing is not filled with
water before starting, it will not begin pumping.
NOTICE
Pump casing must be filled with water before using
pump. Otherwise pump will not be able to begin
pumping.
WARNING
DO NOT open fill cap if pump is hot! Water inside may be
under pressure.
4. Check for leaks between pump and engine. If water
is leaking between the pump and engine housing,
the seal inside the pump may be worn or damaged.
Continued operation of the pump is not recommended.
Further usage of the pump under these conditions may
cause severe water damage to engine.
HOSES AND CLAMPS
1. Check that all hoses are securely attached to the pump.
Make certain suction hose (Figure 3) does not have
any air leakage. Tighten hose clamps and couplings
as required.
6. The discharge hose is usually a collapsible (thinwalled) hose, however if a thin-walled discharge hose
is not available, a rigid suction hose can be substituted
in its place.
7. Make sure the suction strainer (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 into the
pump.
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.
CAUTION
DO NOT pump flammable fluids, corrosive chemicals
or fluids containing toxic substances. These fluids can
create potentially dangerous health and environmental
hazards. Contact local authorities for assistance.
CAUTION
This pump uses a water-cooled mechanical seal
to prevent water from seeping into the engine. The
passage of water through the pump casing lubricates
the seal and prevents it from overheating. NEVER
operate the pump without water in the casing as this
will cause damage to the mechanical seal.
2. It is recommended that 2 clamps be used when
securing the suction hose to the inlet side (suction)
of the pump.
3. Remember suction hoses must be rigid enough not to
collapse when the pump is in operation.
4. Check that the discharge hose (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.
5.
NOTICE
Suction and discharge hoses are available from
Multiquip. Contact your nearest dealer for more
information.

MAINTENANCE
PUMP VACUUM TEST
To perform the pump vacuum test do the following:
NOTICE
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.
1. Remove the pump fill cap (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 11, 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 (Figure 11) 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, reset 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
8. To test the flapper valve, shut down 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.
ADJUSTING IMPELLER CLEARANCE
1. If it is necessary to replace impeller or volute, be sure
clearance between impeller and volute is adjusted
correctly.
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. Remove spark plug
to make it easier 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 wears 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.
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. Loo se n the t wo l o c ki ng h an d kno bs ( t u r n
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.
CAUTION
The impeller may develop sharp edges. Use extreme
care when cleaning around the impeller to prevent
being cut.

DO NOT drive so fast that the trailer begins to sway
due to speed.
Allow plenty of room for passing. A rule of thumb is that
the passing distance with a trailer is 4 times the passing
distance without the trailer.
Use the engine and transmission as a brake. Do not
ride the brakes, as they can overheat and become
ineffective.

DRIVING CONDITIONS
When towing a trailer, you will have decreased acceleration,
for the use of your trailer. Again, be sure your hitch and tow
The breakaway switch is connected to the tow vehicle.
Use of a hitch with a load rating less than the load rating
the load rating of the trailer can result in loss of control,
increased stopping distance, and increased turning radius
(which means you must make wider turns to keep from
hitting curbs, vehicles, and anything else that is on the
inside corner). In addition, you will need a longer distance
to pass, due to slower acceleration and increased length.
Be alert for slippery conditions. You are more likely to be
affected by slippery road surfaces when driving a tow
vehicle with a trailer, than driving a tow vehicle without
a trailer.
Check rearview mirrors frequently to observe the trailer
and traffi c.
NEVER drive faster than what is safe.
WARNING
Driving too fast for severe road conditions can result in
loss of control and cause death or serious injury.
Decrease your speed as road, weather, and lighting
conditions deteriorate.
Always check for local trailer tow speed limits in your
area.
WARNING
Do not transport people on the trailer. The transport of
people puts their lives at risk and may be illegal.

TRAILER SAFETY GUIDELINES
vehicle are rated for the Gross Vehicle Weight Rating of
your trailer.
WARNING
Proper selection and condition of the coupler and hitch
are essential to safely towing your trailer. A loss of
coupling may result in death or serious injury.
• Be sure the hitch load rating is equal to or greater
than the load rating of the coupler.
• Be sure the hitch size matches the coupler size.
• Observe the hitch for wear, corrosion and cracks
before coupling. Replace worn, corroded or cracked
hitch components before coupling the trailer to the
tow vehicle.
• Be sure the hitch components are tight before
coupling the trailer to the tow vehicle.
WARNING
An improperly coupled trailer can result in death or
serious injury.
DO NOT move the trailer until:
• The coupler is secured and locked to hitch.
• The safety chains are secured to the tow vehicle.
• The trailer jack(s) are fully retracted.
DO NOT tow the trailer on the road until:
• Tires and wheels are checked.
• The trailer brakes are checked.
Follow all of the safety precautions and instructions in
this manual to ensure safety of persons, equipment, and
satisfactory life of the trailer. Always use an adequate tow
vehicle and hitch. If the vehicle or hitch is not properly
selected and matched to the Gross Vehicle Weight Rating
(GVWR) of your trailer, you can cause an accident that
could lead to death or serious injury.
If you already have a tow vehicle, know your vehicle tow
rating and make certain the trailer’s rated capacity is less
than or equal to the tow vehicle’s rated towing capacity. If
you already have (or plan to buy) a trailer, make certain
that the tow rating of the tow vehicle is equal to or greater
than that of the trailer.

TRAILER SAFETY GUIDELINES
Be sure that the brakes and all of the lights on your trailer
are functioning properly before towing your trailer. Check
the trailer taillights by turning on your tow vehicle headlights.
Check the trailer brake lights by having someone step on
the tow vehicle brake pedal while you look at trailer lights.
Do the same thing to check the turn signal lights. See Trailer
Wiring Diagram section in this manual.
Standard mirrors usually do not provide adequate visibility
for viewing traffi c to the sides and rear of a towed trailer.
You must provide mirrors that allow you to safely observe
approaching traffi c.
WARNING
Improper electrical connection between the tow vehicle
and the trailer will result in inoperable lights and can
lead to collision.
Before each tow, check that the tail lights, brake lights
and turn signals work.
TRAILER TOWING TIPS
Driving a vehicle with a trailer in tow is vastly different
from driving the same vehicle without a trailer in tow.
Acceleration, maneuverability and braking are all diminished
with a trailer in tow.
It takes longer to get up to speed, you need more room to
turn and pass, and more distance to stop when towing a
trailer. You will need to spend time adjusting to the different
feel and maneuverability of the tow vehicle with a loaded
trailer.
Because of the signifi cant differences in all aspects of
maneuverability when towing a trailer, the hazards and risks
of injury are also much greater than when driving without
a trailer. You are responsible for keeping your vehicle and
trailer in control, and for all the damage that is caused if
you lose control of your vehicle and trailer.
responds. Next, make some right and left hand turns.
Watch in your side mirrors to see how the trailer follows
the tow vehicle. Turning with a trailer attached requires
more room.
Stop the rig a few times from speeds no greater than

As you did when learning to drive an automobile, fi nd
an open area with little or no traffi c for your fi rst practice
trailering. Of course, before you start towing the trailer, you
must follow all of the instructions for inspection, testing,
loading and coupling. Also, before you start towing, adjust
the mirrors so you can see the trailer as well as the area
to the rear of it.

The trailer VIN Tag contains the following critical safety
information for the use of your trailer.
GAWR: The maximum gross weight that an axle cansupport.
It is the lowest of axle, wheel, or tire rating.
Usually, the tire or wheel rating is lower than the axle rating,
and determines GAWR.
GVWR: The maximum allowable gross weight of the trailer
and its contents. The gross weight of the trailer includes
the weight of the trailer and all of the items within it. GVWR
is sometimes referred to as GTWR (Gross Trailer Weight
Rating), or MGTW (Maximum Gross Trailer Weight). GVWR,
GTWR and MGTW are all the same rating.
The sum total of the GAWR for all trailer axles may be less
than the GVWR for the trailer, because some of the trailer
load is to be carried by the tow vehicle, rather than by the
trailer axle(s). The total weight of the cargo and trailer must
not exceed the GVWR, and the load on an axle must not
exceed its GAWR.
PSIC: The tire pressure (psi) measured when cold.
VIN: The Vehicle Identifi cation Number.
EMPTY WEIGHT: Some information that comes with the
trailer (such as the Manufacturer’s Statement of Origin)
is not a reliable source for “empty” or “net” weight. The
shipping documents list average or standard weights and
your trailer may be equipped with options.
and install the proper hitch on your tow vehicle.
SUSPENSION SYSTEM
Sway bars, shock absorbers, heavy duty springs, heavy
duty tires and other suspension components may be
required to suffi ciently tow the trailer and pump.
SIDE VIEW MIRRORS
The size of the trailer that is being towed and your state
some states prohibit extended mirrors on a tow vehicle,
except while a trailer is actually being towed. In this
situation, detachable extended mirrors are necessary.
Check with your dealer or the appropriate state agency
for mirror requirements.
HEAVY DUTY FLASHER

ELECTRICAL CONNECTOR
An Electrical Connector connects the lights on the trailer
to the lights on the towing vehicle.
It is wise to carry these warning devices even if you are
vehicle lights.
