GENERAL INFORMATION  
Elevation  
APPLICATION  
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.  
The QP4TZ Trash Pump is designed to be used for dewatering  
applications. Both the suction and discharge ports on the QP4TZ  
trash pump use a 4-inch diameter opening, which allows the  
pump to pump at a rate of approximately 526 gallons/minute  
(gpm) or 2,000 liters/minute (lpm).  
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 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.  
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 3 shows suction  
lift at various elevations.

Trash pumps derive their name from their ability to handle a  
greater amount of debris and solids than standard centrifugal  
pumps.This pump 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.

Table 4 shows percentage drops in performance as elevation

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 COMPONENTS  
Figure 2 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.

entering the fuel system. Remove wing-nut on side of air  
filter cover to gain access to filter element.  
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.  
4. Speed Control Lever – This lever is connected to the  
throttle control which is located on the side of the engine  
compartment cover. Use this lever to control engine speed.  
5. Dip Stick – Remove dipstick to determine if the engine oil  
level is low. If low, add oil as specified.

SETUP (PUMP)  
Before Starting  
Suction and discharge hoses are  
available from Multiquip. Contact  
your nearest dealer for more  
information.  
NOTE  
1. Read safety instructions at the  
beginning of manual.  
2. Place pump as near to water as  
possible on a firm and flat level  
surface.  
5. The discharge hose is usually a collapsible (thin-walled)  
hose, however if a thin-walled discharge hose is not avail-  
able, a rigid suction hose can be substituted in its place.  
3. Toprimepump,removefillcap(Figure2)andfillpumpcasing  
with water.If the pump casing is not filled with water before  
starting, it will not begin pumping.  
6. Make sure the suction strainer (Figure 2) 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  
Pump casing must be filled with water before using pump.  
Otherwise pump will not be able to begin pumping.  
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.  
WARNING  
DO NOT open fill cap if pump is hot! Water inside may be  
under pressure.  
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.  
4. Checkforleaksbetweenpumpandengine.Ifwaterisleaking  
between the pump and engine housing, the seal inside the  
pumpmaybewornordamaged.Continued operationofthe  
pumpisnot recommended.Furtherusageofthe pumpunder  
theseconditionsmaycauseseverewaterdamagetoengine.  
Hoses and Clamps  
1. Check that all hoses are securely attached to the pump.  
Make certain suction hose (Figure 2) does not have any air  
leakage.Tighten hose clamps and couplings as required.  
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. Itisrecommendedthat 2 clampsbeusedwhensecuringthe  
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 2) 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.

MAINTENANCE (PUMP)  
Pump Vacuum Test  
Adjusting Impeller Clearance  
1. If it is necessary to replace impeller or volute, be sure  
clearance between impeller and volute is adjusted correctly.  
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.  
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.  
To perform the pump vacuum test do the following:  
1. Remove the pump fill cap (Figure 2), and fill the pump with  
water.  
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.  
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 13, 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.  
Remember as the impeller wears  
down, additional shims may be required to maintain the  
clearance between the impeller and insert.  
*4. Place the Pump VacuumTester (P/N 7000030) over the  
pump suction (inlet) opening (Figure 13) 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 reset 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 2)  
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.  
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  
6. 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.  
when cleaning around the impeller to prevent being cut.

PREPARATION FOR LONG -TERM STORAGE  
Pump Storage  
z
Pull the recoil starter grip slowly. STOP when it feels  
tight. This closes the intake and exhaust valves  
(compression position), and helps prevents rust from  
forming.  
For storage of the pump for over 30 days, the following is  
required:  
z
z
z
Drain the fuel tank completely.  
z
z
Wipe any oil or dirt that may have accumulated on the  
engine.  
Remove the drain plug from the pump and drain out any  
water left in the housing.  
Run the engine for about 3 minutes and then stop.  
Stop the engine. Drain the engine crankcase oil while  
the engine is still warm. Fill engine crankcase with fresh  
oil.  
z
Remove the pump cover and clean the inside of pump  
housing. Coat the inside of pump housing with a light  
film of oil to reduce corrosion. A spray can of oil works  
well for this application.  
z
Pull the recoil starter grip (Figure 17) 2 or 3 times. DO  
NOT start the engine.  
z
z
z
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.
