ST-1500 SERIES SUB. PUMP — GENERAL INFORMATION
Introduction
The Multiquip Model ST-1500 series submersible pumps are
designed to pump water and is used for the draining (dewatering) of swimming pools, well casings construction sites,
cofferdams, manholes, transformer vaults and excavations.
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 (ST1503A) or 1.5-inch (ST-1503CUL) 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 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 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.
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 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.
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.
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.
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.
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.
1.
2.
3.
4.
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.
Volute/Impeller – Impellers are constructed of high-chrome
ductile iron to minimizes wear and prolong service life.
Electric Motor – The ST-1503A submersible pump utilizes
a 60 Hz, single-phase, 115 VAC, 0.5 HP electric motor. The
ST-1503CUL submersible pump utilizes a 60 Hz, singlephase, 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.
Discharge Port – Connect a 2-inch (ST-1503A) or 1.5inch (ST-1503CUL) 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 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.
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 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.
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.

ST-1500 SERIES SUB. PUMP — FLOAT SWITCHES
Float Switch Theory
Design Features
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.
Constructed of rigid, durable ABS polymer ultrasonically welded.
The all-steel mercury switch is held by positioning pins. Interior
is filled with cell foam.
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.
■ 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).
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.

ST-1500 SERIES SUB. PUMP — FLOAT SWITCH (PIGGY-BACK)
Float Switch
Single or dual control float switches can be used for the unattended operation of the submersible pump. When using the piggyback power configuration (plug), the ST-1500 series pumps DO NOT require the use of a control box. In this configuration (piggyback), the SW-1 (single float switch) or SW-2 (dual float switch) are required. Figure 6 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
5. DO NOT install cord under hose clamp.
4.
Using a screwdriver, tighten the hose clamp. DO NOT overtighten. Make sure the float cord is not allowed to touch the
excess hose clamp band during operation.
NOTE
Figure 6 shows a single float switch
application. For dual float switch
capability use a Model SW-2 mercury
type float switch.

ST-1500 SERIES SUB. PUMP — FLOAT SWITCH (CONTROL BOX)
Control Box (CB3)
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.

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.
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.
NOTE
Electrical connections to the power
source should only be performed by
a licensed electrician or qualified
personnel.
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. NEVER let the pump 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.

LUBRICATION
To check the oil level of the mechanical seal, perform the
following:
1. Lay the pump (Figure 11) 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.
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.
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.
