QP-402H — GENERAL INFORMATION  
APPLICATION  
Elevation  
The QP204H Centrifugal Pump is designed to handle all types  
of clear water applications. It is ideal for residential use such as  
dewatering basements and swimming pools. Both the suction  
and discharge ports on the QP-402H pump use a 4-inch diameter  
opening, which allows the pump to pump at a rate of  
approximately 425 gallons/minute (gpm) or 1,615 liters/minute  
(lpm).  
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.  
Centrifugal 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.

Standard Centrifugal Pump  
Table 4 shows percentage drops in performance as elevation  
increases.  
Standard centrifugal pumps provide an economical choice for  
general purpose dewatering. These types of pumps should only  
be used in clear water applications (agricultural, industrial,  
residential) as they have a limited solid handling capability of  
only 10% by volume.

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  
ground, on 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.

1. Pump –The model QP-402H is a 4-inch centrifugal pump  
used in general de-watering applications. Typical  
dewatering applications consist of dewatering basements  
and swimming pools.  
6. Suction Port – Connect a 4-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.  
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.  
8. Drain Plug – Remove this plug to drain water from the  
pump.  
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.  
9. 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.  
3. Discharge Port – Connect a 4-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 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.

INITIAL SERVICING  
6. Choke Lever – Used in the starting of a cold engine, or in  
cold weather conditions. The choke enriches the fuel  
mixture.  
The engine (Figure 4) must be checked for proper lubrication and  
filled with fuel prior to operation. Refer to the manufacturers engine  
manual for instructions and details of operation and servicing.The  
engine shown above is a HONDA engine, operation for other  
types of engines may vary somewhat.  
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.  
1. Fuel Filler Cap – Remove this cap to add unleaded  
gasoline to the fuel tank. Make sure cap is tightened  
securely. DO NOT over fill.  
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.  
CAUTION - Fueling The Engine  
Adding fuel to the tank should be done only when  
the engine is stopped and has had an  
opportunity to cool down. In the event of a fuel  
spill, DO NOT attempt to start the engine until  
the fuel residue has been completely wiped up,  
and the area surrounding the engine is dry.  
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

QP-402H — PRE-SETUP (PUMP)  
Pre-Setup (Pump)  
Suction and discharge hoses are  
1. Read safety instructions at the  
beginning of manual.  
NOTE  
available from Multiquip. Contact  
your nearest dealer for more  
information.  
2. Place pump as near to water as  
possible,onafirmflat,levelsurface.  
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  
Pump casing must be filled with water before using pump.  
Otherwise pump will not be able to begin pumping.  
CAUTION - Strainer  
WARNING - High Pressure  
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.  
DO NOT open fill cap if pump is hot!  
Water inside may be under pressure.  
The possibility exists of scalding,  
resulting in severe bodily harm.  
CAUTION - Flammable Fluids-Chemicals  
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.  
CAUTION - Mechanical Seal  
Hoses and Clamps  
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.  
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.  
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.

QP-402H — MAINTENANCE (PUMP)  
Pump Vacuum Test  
CAUTION - Pump Priming  
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.  
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.  
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.  
To perform the pump vacuum test do the following:  
1. Remove the pump fill cap (Figure 2), 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 (next page), 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 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.  
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.  
25 in. Hg (inches of mercury)  
translates into 25 feet of lift at sea  
level.
