GENERAL INFORMATION
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
WARNING
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.

Figure 2. Submersible Pump Components
Figure 2 shows the location of the basic components for
the ST2010 series submersible pumps. Listed below is a
brief description of each component.
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.
2. Volute/Impeller — Volute is constructed of cast iron
and impeller is made of cast ductile iron to minimize
wear and prolong service life.
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.
4. Discharge Port — Connect a 2-inch hose to this port.
Remember to adequately support the discharge hose
to avoid stress on the pump.
5. AC Power Cable — This unit is supplied with an AC
power cable. Always check the cable for signs of wear.
NEVER use a defective power cable. Replace the cable
immediately if the cable is worn or defective.
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.
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.
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
damage to the pump.
9. Mechanical Oil Seal Plug — Remove this plug to
check and add hydraulic oil (Shell 32 or equivalent)
to the oil cavity. This oil protects the mechanical seal.
Oil cavity should be full enough to cover seal spring.

FLOAT SWITCHES
FLOAT SWITCH THEORY
Mercury monitoring is a mercury-switch actuated, liquid-
level control that has proven to be more economical
and longer lasting than other types of liquid-level control
systems, easily replacing and improving upon diaphragm
switches, air bubble systems and electro-mechanical
switches most often relied upon in the past.
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 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.
DESIGN FEATURES
Constructed of rigid, durable ABS polymer ultrasonically
welded. The all-steel mercury switch is held by positioning
pins. Interior is filled with cell foam.
Suitable for most liquid environments.
Hermetically sealed.
Thick-walled non-corrosive PVC plastic enclosure.
Pressure tested to 60 ft. (18.2 meters).
Mercury switch reliability, proven to 500,000 cycles.
Standard SJO, 16-gauge, 2 conductor cord (20 ft./6.09 m).

FLOAT SWITCH (PIGGY-BACK)
FLOAT SWITCH
Single or dual control float switches (Figure 6) can be used
for the unattended operation of the submersible pump.
When using the piggy-back power configuration (plug),
the ST-2010 series pumps DO NOT require the use of a
control box. In this configuration (piggy-back), the SW-1
(single float switch) or SW-2 (dual float switch) are required.
The illustration below is an example of a single float switch
application.
Mounting The Float Switch
1. Determine the required cord tether length as shown in
Figure 6 and Table 3.
2. Place the cord into the clamp as shown in Figure 6
3. Secure the clamp to the discharge hose as shown in
Figure 6. DO NOT install cord under hose clamp.
4. Using a screwdriver, tighten the hose clamp. DO NOT
over- tighten. Make sure the float cord is not allowed
to touch the excess hose clamp band during operation.
NOTICE
Figure 6 shows a single float switch application. For
dual float switch capability use a Model SW-2 mercury
type float switch.
Figure 6. Single Float Switch Application Diagram
PAGE 14 —ST2010 SERIES SUBMERSIBLE PUMP • OPERATION AND PARTS MANUAL — REV. #3 (12/07/12)
FLOAT SWITCH (CONTROL BOX)
CONTROL BOX
For special remote pumping applications of the submersible
pump, a control box (Model CB3 - for ST2010, ST2010A,
ST2010CUL, and ST2010TCUL and Model CB6 - for
ST2010B) may be required. This water-resistant control box
provides watertight housing and glands to prevent water
from leaking into the box, and a float switch interface. When
using the CB3 control box, only the SW-1WOP float switch
(2) can be used (no plug, bare wires).

OPERATION
HOSE CONNECTIONS
Connect a 2-inch hose to the discharge port on the pump
as shown in Figure 9. Make sure that the hose is attached
correctly to the discharge port.
PUMP POWER CONNECTIONS
(PIGGY-BACK CORD ONLY)
1. Make sure the circuit breaker supplying power to the
pump is in the OFF position.
2. Connect the float switch or switches to the AC power
receptacle as shown in Figure 6.
ATTACHING LIFTING ROPE
1. Attach a suitable lifting cable (rope) to the carrying
handle (Figure 9) on the pump and lower the pump
into place. For applications where there is an excessive
amount of mud, grit or silt, the use of a support platform
is desirable. When pumping water from swimming pool
type applications where there is little or no debris, the
support platform is not required.
Figure 9. Submersible Pump Upright
(Correct Position)
2. Make sure the pump is always placed in an upright
position, not tilted (Figure 10). Never position the pump
directly on a soft, loose bottom. Remember to attain
maximum pumping capacity and prevent excessive
wear, position the pump so it will not burrow itself into
sand or clay.
Figure 10. Submersible Pump Tilted
(Incorrect Position)
3. If all of the pump's electrical requirements have been
met, place the circuit breaker or power ON/OFF switch
in the ON position.

CONTROL BOX INSTALLATION
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.
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.
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.
DANGER
The ST2010 Series submersible
pumps are designed to work with a
control box. The control box contains
the necessary electronics (float
switch connections) to operate
the pump. Remember the control
box contains hazardous voltages.
Disconnect all sources of power
before installing or servicing. There exists the possibility
of electrocution, electric shock or burn, which can cause
severe bodily harm or even death!
CAUTION
This control box should only be installed or serviced by
a licensed electrician or qualified personnel.
CAUTION
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.
POWER CORD REQUIREMENTS
When routing the 115 VAC/230V, 60 Hz, single-phase power
via a power cord to the control box, always use the correct
wire size. Please refer to Table 4 below (Cord Length/Wire
Size) to determine the correct wire size. Incorrect wire size
can adversely affect the performance of the pump.
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.
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.

CONNECTING AC POWER TO THE CONTROL BOX
1. The AC power cord (input) should have three wires.
Each wire is color coded. The colors are WHITE,
BLACK and GREEN.
2. Remove the AC input connector housing from the
control box, then route the power cord through the
cable gland on the control box.
3. Connect the AC power cord to the contactor as shown
in Figure 7 and Table 6.
4. Tighten the connector housing to ensure a tight fit
between the power 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.
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.
CONNECTING AC POWER TO THE PUMP
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.

NOTICE
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.
CONTROL BOX INSTALLATION
2. Remove the pump AC input connector housing from
the control box, then route the power cord through the
cable gland on the control box.
3. Connect the pump power cord to the contactor as
shown in Figure 7 and Table 7.
TURNING ON THE 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.
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.
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.
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.
6. To stop the pump from pumping, place the operation
switch in the OFF position.

MAINTENANCE
LUBRICATION
To check the oil level of the mechanical seal perform the
following:
1. Lay the pump (Figure 12) on its side with the oil plug
facing upwards.
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.
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.
5. If oil level is low, fill with SAE 10 weight non-detergent
hydraulic oil (i.e. Shell Turbo 32 or equivalent). Fill oil
cavity 75% to 85% full (allow air space for expansion).
See Table 1 for pump oil cavity capacity.
IMPELLER
1. Make sure the clearance between the impeller and
the friction disk is approximately .012 - .020 inches
(.304 - .508 mm.)
2. If impeller is defective or badly worn, replace impeller
immediately.
