PUMP COMPONENTS
Figure 2. ST1/ST1F Pump Components
Figure 2 shows the location of the basic components, for
the ST1 and ST1F submersible pumps.
Listed below is a brief explanation of each component.
1. Power Cord — SJTW, 18AWG, 3C 3.3M (10 ft) with
molded NEMA 5-15 Plug. NEVER use a defective
power cord. See Table 3 for Extension Cord support
data.
2. Rugged Pump Casing — the pump is designed
with an aluminum casing for durability and corrosion
resistance. The casing also provides optimum cooling
for the motor.
3. Pump Adapter Coupler — the polyethylene adapter
provides threaded connection to a common garden
hose with a ¾” female adapter end. Coupler is a male
¾” GHT.
4. Carry Handle — a molded handle is formed with the
top cover, and should be used to transport the pump
and provide an anchoring point to attach a cord.
NEVER carry or place the pump into operation via
the power cord.
5. Power Cord Strain Relief — a molded, and reinforced
strain relief assembly is provided for the power cord.
6. Thermal Overload — (internal) the pump detects
high motor temperatures, and provides automatic
shutdown until the motor cools.
7. Capacitor Start — (internal) a powerful 250V X 12 uF
start capacitor provides immediate motor starts, while
minimizing high start amperage.
8. Powerful Electric Motor — (internal) an a synchronous,
2-pole motor operates on 115 VAC 1- phase, 60Hz
power and delivers 3,450 RPM.
9. Polyethylene Impeller and Clean-out Screen —
(internal) an abrasive resistant open impeller and
easy to access clean-out screen support simple
maintenance actions as necessary.
10. Rugged Float Switch — the ST1F pump employs

ST1/ST1F SUBMERSIBLE PUMP • OPERATION AND PARTS MANUAL — REV. #0 (02/01/21) — PAGE 11
For optimum performance and motor longevity, it is best
to: (1) position the pumps in a vertical, upright position (2)
ensure 115VAC single-phase 60 Hz power is supplied (3)
limit the lengths of extension cords (4) ensure that only
fresh water is being pumped (5) ensure the pumps remain
fully submerged as long as possible (6) NEVER allow the
pumps to run ‘Dry’ and (7) limit the amount of debris and
particles that could enter the units.
The pumps are designed with internal overload protection
if extreme overheating of the motor occurs, but this
feature should not be relied upon as a common means of
operations.
Continual overheating of the motor often caused by
improper electrical power, extreme extension cord lengths
(combined with unsuitable cord gauge), operating ‘DRY’,
continual operations for long extended periods of time and
excessively high fluid temperature operations will shorten
the life of the pumps.
Pumping performance of these pumps (Flow, Head, Velocity
and Pressure) is based upon the application givens that
include: discharge hose or pipe length, friction loss factors,
and general rise/run figures. The pumps provide for
dewatering surfaces down to approximately ¼”.
GENERAL INFORMATION
The Multiquip models ST1 and ST1F are compact, general
utility submersible pumps designed to move fresh water
in many dewatering applications such as: flooded rooms,
fountains and waterfalls, swimming pools and spas, simple
fill-tank requirements, and other low-flow water transfer
operations.
The pumps do not have ON/OFF switches and automatically
begin to operate once the power cord is connected to an
115V electrical source. The model ST1F provides an
integrated mechanical float switch assembly that allows
the pump to start and stop automatically when a prefixed
water level has been reached.
The ST1 and ST1F can discharge a very limited size
and amount of debris, and are not designed to handle
chemicals, salts, or other low pH liquids. The unit’s best
operate with water temperatures below 140° F.
For discharge, the pumps provide a single, common
¾” Garden Hose Thread GHT male coupler. Excessive
discharge hose or pipe lengths will affect flow and head
performance (see Performance Curve Chart in this manual).
NOTICE
DO NOT allow the pumps to run ‘Dry’, or be allowed to
freeze with water still in the unit.

PRE-OPERATION SETUP
1. Avoid using this pump in conditions where mud, grit,
silt, or heavy debris is present. If debris is present, it
is highly recommended to place the pump on a simple
platform to keep the suction inlet free from direct
contact with an undesirable surface.
2. The pump should be installed in a free standing
(upright) position. See Figure 4 and Figure 5.
3. It is highly recommended to tie a rope around the carry
handle for lifting and positioning the pump. DO NOT
use the power cord for lifting the pump.
4. For maximum water flow, the discharge hose/pipe
should be kept as short as possible, with minimum
elevation above the pump.

OPERATION (ST1)
See Figure 6 for standard ST1 Operation Setup.
1. Prepare the pump for the application by securely
threading a ¾” garden hose or ¾” GHT pipe onto the
discharge port.
2. Orient the hose/pipe in manner that limits extreme
bends, kinks, or twists. Ensure the hose/pipe discharge
end is positioned where you desire the flow of water
to travel.
3. Tie a rope or cord (not supplied) around the carry
handle to lower and retrieve the pump from the water
source.
4. Consider using a support platform base (not supplied)
for the pump to sit upon to keep the suction inlet
from directly engaging with any silty, sandy bottom
conditions.
5. Slowly lower the pump to its operating position ensuring
that it remains vertical. Ensure that the pump remains
submerged as long as possible, and do not allow the
pump to run dry for more than a minute.
6. Connect to the pump’s power cord to the proper
electrical source. The pump will automatically operate
as soon as power is connected.
7. Once electrical power is introduced, the water should
flow from the discharge hose/pipe within seconds.
Check to the flow rate to be steady and continuous.
CAUTION
Applying incorrect power (voltage phasing) to the
submersible pump can cause severe damage to the
pump.
Make sure that the correct voltage and phase are
transferred to the pump at all times.
DANGER
NEVER grab or touch a live power
cord. DO NOT stand in water when
connecting the pump’s power cord into
a voltage source.The possibility exists
of electrical shock, electrocution and
possibly death!
Figure 6. Standard ST1 Pump Setup
8. Once the watering/dewatering operation is complete:
