Figure 3. Submersible Pump Components
Figures 3 shows the location of the basic components, for
the ST3020B1/BCUL submersible pump. Listed below is
a brief explanation of each component.
1. AC Power Cable – This unit is supplied with a 50-ft.
(approximately 15 meters) AC power cable with a
NEMA L6-20P grounding-type plug. Always check
the cable for signs of wear. use a defective
power cable.
2. – Always carry the submersible pump
by its handle. carry the pump by its power cord.
Carrying or lifting the pump by the power cord will cause
undue stress on the cord and can ultimately dislodge
the cord from the pump.
3. – Connect a 3-inch hose to this port.
Remember to adequately support the discharge hose
to avoid stress on the pump.
4. – 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.
5. Mechanical Seal – The hydraulic oil in the pump cavity
is designed to provide cooling for the pump seal. This
allows the pump to run dry for a limited period of time.
6. – Remove this plug to check
and add lubrication oil (ISO VG32 grade) to the oil
cavity. This oil protects the mechanical seal. Oil cavity
should be full enough to cover seal spring.
7. Strainer Base – This strainer base is made of electro-
coated steel which is resistant to hardware corrosion.
pump large objects or debris with this pump.
This pump is for pumping water only. For dewatering
purposes, always place the strainer base on a platform.
8. – Impellers are constructed of ductile
iron to minimize wear and prolong service life.
9. Electric Motor – These submersible pumps utilize a
60 Hz, single-phase, 230 VAC, 2 HP electric motor.
Consult with a licensed electrician before connecting
motor to a power source and control boxes. Observe
all city and local safety codes.
