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.

Figure 2. ST1/ST1F Pump Components
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
a mechanical type float switch comprised of a heavy
polyethylene jacket, molded power cord with strain
relief, and is internally connected to the motor for
automatic service.
