QP-301TH — 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 QP-301TH Trash Pump is designed to be used for de-  
watering applications. Both the suction and discharge ports on  
the QP-301TH trash pump use a 3-inch diameter opening, which  
allows the pump to pump at a rate of approximately 416 gallons/  
minute (gpm) or 1,575 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.  
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.  
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.  
Power Plant

a built-in oil alarm engine shut-down feature. In the event the oil  
level is low the engine will automatically shut-down.

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.  
Table 4 shows percentage drops in performance as elevation  
increases.

Elevations  
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

the water as possible.

Pump Support  
The pump should always be placed on solid stationary ground  
in 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.

QP-301TH — PUMP COMPONENTS  
Figure 2 shows a typical application using the QP-301TH Centrifugal 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 (38 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 2. QP-301TH Pump Application  
1. Pump The model QP-301TH is a 3-inch trash pump 6. Suction Port – Connect a 3-inch inlet hose to this port.  
used in general de-watering applications. Typical  
dewatering applications consist of manholes, septic tanks,  
fast and slow seepage ditch water, silt water, mud water  
and muck water.  
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. 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.  
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. Drain Plug – Remove this plug to drain water from the  
pump.  
3. Discharge Port – Connect a 3-inch discharge hose to this

port.  
clean-out area.  
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.  
11. Locking Knobs– Turn both knobs clockwise to secure  
clean-out cover, turn counter-clockwise to release cover.  
12. 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.  
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.
