ST2037, 47, 47B, 38P, 40T SUB. PUMP — GENERAL INFORMATION

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.

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.

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 located
on top of the pump. 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.

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
measurement threads.

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.

PAGE 10 — ST2037,47, 47B, 38P, 40T SUB. PUMPS — OPERATION AND PARTS MANUAL — REV. #3 (06/15/10)

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.

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.

2. Volute/Impeller – Impellers are constructed of Nitorile
Rubber to minimizes wear and prolong service life.

3. Electric Motor – These submersible pumps utilize a 60
Hz, single-phase, 115 VAC, 1 HP electric motor. Consult

licensed electrician

with 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.

before connecting motor to a

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 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 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.

9. 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.

ST2040T

5. 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.

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 electromechanical 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 (close, Figure 4) or

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.

CLEAN-UP AND MAINTENANCE

Pump Shut-Down/Clean-up

1. Remove the power from the pump by turning off the circuit
breaker or switch that provides power to the pump. Remem­ber to make sure that hands are dry (not wet), and feet are not
standing in water when removing disconnecting power from
the pump.

2. Using the lifting rope, lift the pump up from its current position.
Remove the discharge hose from the discharge port on the
pump.

3. Remove all power cables and float switches from the control
box. Place cables and float switches in a suitable container
where they will not get damaged.

4. If the pump was used to pump mud, grit or silt, flush vigorously
with clean water.

5. Remove the pump from the water. Wipe off any mud or debris
that might have attached itself to the pump.

6. Store pump in a clean dry place away from dirt and debris.

LUBRICATION

To check the oil level of the mechanical seal perform the
following:

DISASSEMBLY

Refer to Figure 11 for location of parts to be removed.

For Model ST2037, ST2047, ST2047B and ST2038P:

1. Position pump upside down.

2. Remove strainer.

3. Remove casing.

4. Remove the pump impeller.

5. Remove the liner.

6. Remove the oil plug and packing.

OIL CHECK

1. Check pump oil at oil cavity plug (Figure 11). Check every 300
hours and change hydraulic oil every 6 months (1,000 hours)
or as needed.

2. While checking the hydraulic oil level, also check the
condition of the hydraulic oil in the seal cavity. Discolored
milky oil indicates a failure of the water seal. If this occurs,
replace water seal.

3. 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 mechanical seal oil capacity.

IMPELLER

For Model ST2040T:

1. Position pump upside down.

2. Remove casing.

3. Remove the pump impeller.

4. Remove the oil plug and packing.
