GENERAL INFORMATION
DESCRIPTION
The QP2E 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 pump use a
2-inch diameter opening, which allows the pump to pump
at a rate of approximately 158 gallons/minute (gpm) or 600
liters/minute (lpm).
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.
ENGINE
This centrifugal pump is powered by an air-cooled 4-cycle,
single cylinder Robin EX130D51111 gasoline engine.
STANDARD CENTRIFUGAL PUMP
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.
SUCTION LIFT
This pump 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.
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 3
shows suction lift at various elevations.
Table 4 shows percentage drops in performance as
elevation increases.

PUMP COMPONENTS
Figure 2 shows a typical application using the QP2E
centrifugal pump. Please note that this pump is intended
for the removal of clean water.
QP2E Pump ApplicationFigure 2.
Pump1. — A 2-inch centrifugal pump used in general de-
watering applications. Typical dewatering applications
consist of dewatering basements and swimming
pools.
Fill Cap2. — 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.
Discharge Port3. — Connect a 2-inch discharge hose
to this port.
Worm Clamp4. — 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.
Discharge Hose5. — 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.
Suction Port6. — Connect a 2-inch inlet hose to this
port. Use two worm clamps to secure the hose.
Suction Hose7. — 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.
Drain Plug8. — Remove this plug to drain water from
the pump.
Strainer9. — 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.

associated with a loose component.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.
OPERATION
Once the engine has started, move the engine throttle1.
lever quickly to the fast position to begin pumping. 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.
STOPPING THE ENGINE
Place the throttle lever (Figure 9) in slow position, and1.
listen for the engine speed to decrease.
Place the Engine ON/OFF switch (Figure 7) in the2.
"OFF" position.
Place the fuel valve lever (Figure 6) in the "3. OFF"
position.
WARNING
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.
CAUTION

MAINTENANCE
PUMP VACUUM TEST
To perform the pump vacuum test do the following:
Remove the pump fill cap (Figure 2), and fill the pump1.
with water.
Start the engine as outlined in the initial start-up2.
section, and wait for the pump to begin pumping.
As shown in Figure 11, place a water hose inside3.
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.
Place the Pump Vacuum Tester (P/N 7000030) over4.
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.
Check and make sure that there are no air leaks5.
between the vacuum tester and the inlet port on the
pump. If air leaks are present reset vacuum tester.
Run the pump for a few minutes while monitoring the6.
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.
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.
NOTICE
25 in. Hg (inches of mercury) translates into 25 feet of
lift at sea level.
If the vacuum tester gauge indicates a reading below7.
-20 in. Hg, it can then be assumed that the pump is
not functioning correctly, and corrective action needs
to be taken.
To test the flapper valve, shut down the engine. The8.
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.
