STOWT-20H — 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 STOW Model T-20H Trash Pump is designed to be used  
for de-watering applications. Both the suction and discharge  
ports on theT-20H pump use a 2-inch diameter opening, which  
allows the pump to pump at a rate of approximately 158 gallons/  
minute (gpm) or 598 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  
only 18 feet rather than the 25 feet at sea level. Table 3 shows  
suction lift at various elevations.  
Power Plant

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.

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.

STOWT-20H — PUMP COMPONENTS  
Figure 2 shows a typical application using the STOW T-20H 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 inch (25 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.

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 2-inch discharge hose to this

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.

STOWT-20H — 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  
CAUTION :  
DO NOT attempt to start the engine unless  
the pump has previously been primed with  
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.  
water. Severe pump damage will occur if  
pump has not been primed.  
To perform the pump vacuum test do the following:  
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.  
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.  
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 wear  
3. As shown in Figure 17 (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.  
down, additional shims may be required to maintain the  
clearance between the impeller and insert.  
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.  
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  
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 reseat vacuum tester.  
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 counter-  
clockwise) and remove clean-out cover.  
25 in. Hg (inches of mercury)  
translates into 25 feet of lift at sea  
level.  
3. Clean and remove dirt, debris from pump casing.Inspect  
impeller and volute for wear. Replace any damaged or  
worn parts.  
7. If the vacuum tester gauge indicates a reading CAUTION :  
below -20 in. Hg, it can then be assumed that the pump  
is not functioning correctly, and corrective action needs  
to be taken.  
The impeller may develop sharp edges.  
Use extreme care when cleaning around  
the impeller to prevent being cut.  
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.
