ST-1500 SERIES 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 ST-1500 series 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 cast iron ductile type impeller is attached to the output shaft of
a 0.5 HP (ST-1503A) or 0.3 HP (ST-1503CUL) 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 (ST-
1503A) or 1.5-inch (ST-1503CUL) 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 discharge hose (not
supplied) should be connected to the discharge port. 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
or operate in a explosive or flammable environment.
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.
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 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.

ST-1500 SERIES SUB. PUMP —COMPONENTS
Figure 2. Submersible Pump Components
Figures 2 shows the location of the basic components, for the
ST-1500 series submersible pumps. Listed below is a brief
explanation of each component.
5.
AC Power Cable – This unit is supplied with a 25 ft. (7.6
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.
1.
Strainer Base – This strainer base is made of stainless
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.
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.
3.
Volute/Impeller – Impellers are constructed of high-chrome
ductile iron to minimizes wear and prolong service life.
7.
Thermal Overload Protection – This pump is equipped
with a thermal overload protection device that will shutdown
the motor in the event of high operating temperatures.The
motor will automatically restart once the temperature returns
to an acceptable operating temperature.
Electric Motor –The ST-1503A submersible pump utilizes
a 60 Hz, single-phase, 115VAC, 0.5 HP electric motor.The
ST-1503CUL submersible pump utilizes a 60 Hz, single-
phase, 115 VAC, 0.33 HP electric motor. Consult with a
licensed electrician before connecting motor to a power
source. Observe all city and local safety codes.
8.
9.
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.
4.
Discharge Port – Connect a 2-inch (ST-1503A) or 1.5-
inch (ST-1503CUL) hose to this port. Remember to
adequately support the discharge hose to avoid stress on
the pump.
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.

ST-1500 SERIES 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 (closed, 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.

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 and improper impeller
clearance. 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?
