ST2037, 47, 47B, 38P, 40T SUB. PUMP GENERAL INFORMATION  
If the pump was used to pump water containing mud, silt, use  
clean water to flush out the pump after each use.  
Introduction  
The Multiquip Model ST2037, ST2047, ST2047B, ST2038P, and  
ST2040T submersible pumps are designed to pump water and  
is used for the draining (de-watering) of swimming pools, well  
casings construction sites, cofferdams, manholes, transformer  
vaults and excavations.  
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 Nitorile rubber over steel impeller is attached to the output  
shaft of a 1HP 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  
located at the top of the pump which accepts a 2-inch hose.  
A pump fully submerged pump 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.  
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.  
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 located  
on top of the pump.The discharge hose should be adequately  
supported to avoid stress on the pump.  
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.  
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.  
Control Box Installation Warnings  
DANGER  
When installing the CB3 control box, the  
possibility exists of electrical shock,  
electrocution and possibly death! NEVER have  
untrained personnel perform the installation.  
ALWAYS have qualified service personnel (licensed  
electrician) perform the installation.  
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  
WARNING  
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.  
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.  
DO NOT install the pump directly into an area where there is a  
heavy buildup 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.  
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.

Figure 2. Submersible Pump Components  
Figures 2 shows the location of the basic components, for the  
ST2037, ST2047, ST2047B, ST2038P, and ST2040T  
submersible pumps. Listed below is a brief explanation of each  
component.  
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.  
1.  
Strainer Base This strainer base is made of electrocating  
steel which is resistant to hardware corrosion. DO NOT  
pump large objects or debris with this pump.This pump is  
for pumping water only.For de-watering purposes, always  
place the strainer base on a platform.  
7.  
Thermal Overload Protection – This pump is equipped  
with a 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.  
2.  
3.  
Volute/Impeller – Impellers are constructed of Nitorile  
Rubber to minimizes wear and prolong service life.  
8.  
9.  
Mechanical Seal Oil – 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.  
Electric Motor – These submersible pumps utilize a 60  
Hz, single-phase, 115 VAC, 1 HP electric motor. Consult  
with a licensed electrician before connecting motor to a  
power source. Observe all city and local safety codes.  
Mechanical Seal Oil 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.  
4.  
5.  
Discharge Port – Connect a 2-inch hose to this port.  
Remember to adequately support the discharge hose to  
avoid stress on the pump.  
AC Power Cable – This unit is supplied with a 25 ft. (7.6  
meters) or 50 ft. (15.2 meters) 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.

ST2037, 47, 47B, 38P, 40T SUB. PUMP FLOAT SWITCHES  
Design Features  
Float Switch Theory  
Constructed of rigid, durable ABS polymer ultrasonically welded.  
The all-steel mercury switch is held by positioning pins. Interior  
is filled with cell foam.  
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 electromechanical switches most often relied upon in the  
past.  
Suitable for most liquid environments.  
Hermetically sealed.  
Thick-walled non-corrosive PVC plastic enclosure.  
Pressure tested to 60 ft. (18.2 meters).  
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 (close, Figure 4) or  
breaks (open Figure 5) the circuit. Maximum pumping range is  
120 degrees. See Figure 3 below.  
Mercury switch reliability, proven to 500,000 cycles.  
Standard SJO, 16-gauge, 2 conductor cord (20 ft./6.09 m).  
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.UseTable 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.

For special remote pumping applications of the submersible pump, a control box (Model CB3) 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).Shown below (Figure 7) is a wiring layout of  
the CB3 control box. See page 22 for a wiring diagram of the control box.

ST2037, 47, 47B, 38P, 40T SUB. PUMP TROUBLESHOOTING  
Practically all breakdowns can be prevented by proper handling and maintenance inspections, but in the event of a  
breakdown, useTable 8 (PumpTroubleshooting) as a basic guideline for troubleshooting the pump. If the problem cannot be  
remedied, contact Multiquip's service department.  
TABLE 8. PUMP TROUBLESHOOTING  
SYMPTOM  
POSSIBLE PROBLEM  
SOLUTION  
Check that proper voltage (115 VAC, 60 Hz, single-phase ) is being  
supplied to the pump. Also check that there is an adequate amount  
of current (amps) to run the pump. Check power source circuit  
breaker.  
Incorrect voltage/amps?  
If using float switches check wiring, inspect power cord.  
Replace fuse, check cause of blown fuse.  
Check electrical connections?  
Blown power fuse?  
Pump Fails To Start  
Disconnect power cord and check for clogging. Unclog pump. Check  
overload protection device.  
Impeller locked?  
Use multimeter to check motor insulation. Insulation resistance must  
be approximately 15 megaohms. If resistance is low, disassemble  
pump motor and bake windings to dry them.  
Wet motor windings?  
Defective motor and pump  
bearings?  
Check for excessive bearing wear, if worn replace bearings. Replace  
motor if defective.  
Twisted or restricted discharge  
hose?  
Lay hose flat un-kinked. Remove clog from hose line.  
Clean strainer.  
Clogged pump strainer?  
Pump Fails to Deliver Full  
Output  
Use a voltmeter to check voltage while pump is energized. Voltage  
must be within 10%. Check power source (no load and load). If an  
extension cord is used, make sure it has adequate current-carrying  
capacity for the required length.See Table 4.  
Low voltage?  
Impeller worn?  
Replace impeller.  
Replace water seal.  
Tighten securely.  
Defective water seal?  
Loose Oil Fill Plug?
