ST-2005 SERIES SUB. PUMP — GENERAL INFORMATION
Introduction
The Multiquip Model ST-2005 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 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.
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 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.
Control Box Installation Warnings

ST-2005 SERIES SUB. PUMP — COMPONENTS
Figure 2. Submersible Pump Components
Figures 2 shows the location of the basic components, for the
ST-2005 series submersible pumps. Listed below is a brief
explanation of each component.
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.
2. Volute/Impeller – Impellers are constructed of high-chrome
ductile iron to minimizes wear and prolong service life.
3. Electric Motor – All 2005 series submersible pumps
utilizes a 60 Hz, single-phase, 115 VAC, 0.5 HP electric
motor. Consult with a
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 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.
licensed electrician
before
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-2005 SERIES SUB. PUMP — 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 diaphram 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 (close, Figure 4) or
breaks (open, Figure 5) the circuit. Maximum pumping range is

ST-2005 SERIES SUB. PUMP — MAINTENANCE
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.
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.
