general infOrMatiOn  
This pump must always be positioned on a platform in an  
upright position.never operate the pump by a suspended  
rope.To prevent large solids from entering the pump, install  
a wire mesh screen or similar barrier around the pump.  
inTroduCTion  
The Multiquip Model ST-2010 submersible pump is  
designed to pump water and is used for the draining (de-  
watering) of well casings construction sites, cofferdams,  
manholes, transformer vaults and excavations. The ST-  
2010TCUL is designed for heavily debris-laden water and  
the 2-inch discharge port can handle solids up to one inch  
in diameter.  
If the pump was used to pump water containing mud, silt,  
use clean water to flush out the pump after each use.  
do noT allow the pump to run dry, as this will damage the  
pump. During maintenance, dry running is permissible but  
only for a few seconds.  
A cast ductile iron type impeller is attached to the output  
shaft of a 1 HP electric motor which provides adequate  
power for general purpose pumping. This submersible  
pump is supplied complete with an electric power cable,  
and a discharge port which accepts a 2-inch hose.  
never lift the pump by its electrical power cord. alWaYS  
lift the pump by its carrying handle or attach a rope to the  
carrying handle.  
A pump fully submerged in liquid will not freeze, unless  
the liquid freezes. do noT allow a partially submerged  
pump to freeze. The expansion of water freezing in the  
volute may crack the pump, causing expensive repairs. If  
there is any danger of the pump being subjected to freezing  
temperatures, Lift the pump from water and allow it to drain  
thoroughly.  
This pump is ideal for portability because of its light  
weight and carrying handle. For reliability and long life, a  
mechanical seal provides shaft sealing, with an oil chamber  
separating the pump section from the motor.  
The pump when in use, should be installed as free standing  
(upright position) on its strainer base. A 2-inch discharge  
hose (not supplied) should be connected to the discharge  
port.The discharge hose should be adequately supported  
to avoid stress on the pump.  
If the pump jams or the pump rotor locks for any reason,  
disconnect the pump from the power source immediately.  
Allowing the pump motor to cycle ON and OFF under an  
overload condition can burn out the motor.  
For maximum water flow, the discharge hose should be  
kept as short as possible, and with minimum elevation  
above the pump. Remember as the length and/or height  
of the discharge hose is increased, the flow of water will  
be reduced. Also any reduction in the hose size, and any  
fittings such as valves or outlet nozzles, will restrict the  
water flow.  
When replacement of nuts and bolts is required, use only  
recommended parts as referenced in the parts section of  
this manual.This pump uses metric threads. do noT use  
English measurement threads.  
Warning  
To avoid back-siphonage when the pump is switched off,  
ensure that the end of the discharge hose is installed above  
the water level at the final discharge point.  
Explosion or Fire Hazard exists if this  
pump is used with flammable liquids. do  
noT use this pump with flammable liquids.  
do noT install this pump in hazardous  
locations as defined by the National  
Electrical Code, ANSI/NFPA 70.  
When the pump is switched off, the water remaining in the  
hose will run back through the pump. This can be avoided  
by placing a non-return valve in the hose nearest the pump.  
never use this submersible pump to pump flammable  
liquids or operate in a explosive or flammable environment.  
Failure to follow the above referenced precautions could  
result in serious injury or death! Replace pump cord  
immediately if cord becomes damaged or severed. This  
pump must be installed in accordance with National Electric  
Code ANSI/NFPA 70 so as to prevent moisture from  
entering or accumulating with the boxes, conduit bodies  
fittings, float housing or cable.  
Avoid using this pump in conditions where mud, grit, silt  
or other debris are present.These conditions could cause  
blockage and cause excessive pump wear.  
do noT install the pump directly into an area where there  
is a heavy build-up of mud, grit, silt or debris.If this condition  
is present, install the pump on a platform before operating.

never use a defective power cable.Replace the cable  
immediately if the cable is worn or defective.  
1. Strainer base — Made of chrome-plated steel which  
is resistant to hardware corrosion. do noT pump  
large objects or debris with this pump. This pump is  
for pumping water only.Always place the strainer base  
on a platform.  
6. Carrying Handle — Always carry the submersible  
pump by its handle. never carry the pump by its  
power cord. Carrying or lifting the pump by the power  
cord will cause undue stress on the cord and ultimately  
the cord will become dislodged from the pump.  
2. volute/impeller — Volute is constructed of cast iron  
and impeller is made of cast ductile iron to minimize  
wear and prolong service life.  
7. Thermal overload protection — This pump is  
equipped with thermal overload protection device that  
will shut down the motor in the event of high operating  
temperatures.The motor will automatically restart once  
the temperature returns to an acceptable operating  
temperature.  
3. electric motor — All ST2010 series submersible  
pumps utilize a 60 Hz, single-phase, 1.0 HP electric  
motor. The ST2010, ST2010A, ST2010CUL and  
S-2010TCUL operate at 115 VAC while the ST2010B  
operates at 230VAC.Consult with a licensed electrician  
before connecting motor to a power source. Observe  
all city and local safety codes.  
8. mechanical oil Seal — This oil-filled seal provides  
lubrication when running the pump dry. never run  
the pump dry. Running the pump dry will cause severe

Mercury switch reliability, proven to 500,000 cycles.  
Standard SJO, 16-gauge, 2 conductor cord (20 ft./6.09 m).  
HoW iT WorkS  
There is a tilt-sensitive mercury switch hermetically sealed  
within each float. As the liquid level (water) rises or falls,  
the float changes its angle until the mercury switch makes  
(closed, Figure 4) or breaks (open, Figure 5) the circuit.  
Maximum pumping range is 120 degrees. See Figure 3  
below.  
Figure 4. Float Switch (Closed)  
Figure 3. Pumping Range (Float Switch)  
pumping range  
The pumping range of the pump is determined by the float  
switch tether cord. Use Table 3 as guide line to determine  
your required pumping range. Pumping ranges are based  
on non-turbulent conditions. Range may vary due to water  
temperature and cord shape. Please note as the tether  
length increases, so does the variance of the pumping  
range.

route the float switch wires through the cable gland on  
the control box. Attach the wires of the float switch to  
the terminal block as indicated by Table 5, Figure 7  
and Figure 8.  
Single-pHaSe poWer inSTallaTion (inpuT)  
The ST2010, ST2010A, ST2010CUL, and ST2010TCUL  
submersible pumps require 115 V, 60 Hz, single-phase  
power for normal operation.The ST2010B requires 230 V,  
60 Hz, single-phase power.

Applying incorrect power (voltage phasing) to the  
submersible pump can cause severe damage to the  
pump. Please make sure that the correct voltage and  
phase are transferred to the pump at all times.  
2. Tighten the connector housing to ensure a tight fit  
between the cord and the connector body. This will  
prevent the cable from pulling out of the terminal block  
and also prevent moisture from entering the control box.  
3. Determine the length of the float switch wires, then  
secure float switch wires to pump discharge hose.See  
Figure 3 and Table 3 to determine the pumping range.

Turning onTHe pump  
1. If all of the pump's electrical requirements have been  
met, place the circuit breaker or power ON/OFF switch  
in the ON position.  
NOTICE  
2. The CB3 control box has an operation switch located  
on the front cover. This switch has 3 positions; AUTO,  
MANUAL and OFF. The AUTO position allows the  
pump to run in an unattended mode. The MANUAL  
position will let the pump run without the float switches  
controlling the pump. When in the manual mode, be  
careful not to let the pump run dry. Severe damage to  
the pump may occur if it is allowed to run dry.  
It is recommended that the power being supplied to the  
control box always be connected to a circuit breaker  
or a quick disconnect switch.This safety feature allows  
for quick removal of power from the control box in the  
event of an emergency.  
5. Connect the other end of the AC power cord to the  
voltage source. Remember to provide a means of  
disconnecting the power from the control box (circuit  
breaker or quick disconnect switch).Also make sure to  
provide a good earth ground to the control box.  
3. Place the operation switch in the AUTO position. The  
AC power indicator lamp should be lit (ON).  
4. Wait a few seconds and water should begin to flow  
from the discharge hose.
