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

„ 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.

CauTion
This control box should only be installed or serviced by
a licensed electrician or qualified personnel.
ConTrol box mounTing
Mount the control box in an upright vertical position. Make
sure the control box is securely fastened to a flat surface,
that is free of dust, dirt, moisture or any elements that
may contaminate or erode the electronic components of
the control box.
ConneCTing dual FloaT SWiTCH (SW-1Wop)
To ConTrol box
1. Remove the float switch input connector housing, then
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.
Table 5. Float Switch Connections
If you cannot determine what your pump's power
requirements are, look at the vendor supplied identification
name tag attached to the pump or contact Multiquip's
Service/Technical Assistance department.

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.
ConneCTing aC poWerToTHe pump
5. If water is not flowing from the discharge hose or not
flowing freely after a few minutes, remove the power
from the pump and check the system for leaks.
1. AC power is transferred to the pump via a contactor.
The coil of the contactor is energized or de-energized
by the opening and closing of the float switch contacts.
The power cord should have three wires. Each wire
is color coded. The colors are WHITE, BLACK and
GREEN.
6. To stop the pump from pumping, place the operation
switch in the OFF position.

1. Make sure the clearance between the impeller and
the friction disk is approximately .012 - .020 inches
(.304 - .508 mm.)
2. Remove oil fill plug.
3. Visually inspect oil plug hole to verify that oil cavity
is full enough to cover seal spring. Check every 300
hours. Change hydraulic oil every 6 months (1,000
hours) or as needed.
2. If impeller is defective or badly worn, replace impeller
immediately.
4. While checking the hydraulic oil level, also check the
condition of the hydraulic oil in the seal cavity.Block the
opening with a finger and roll pump to one side to drain
oil into a small transparent container. If oil is cloudy or
has water in it, drain oil from pump cavity and replace
hydraulic oil. Check the seal for wear damage.
