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. NEVER use a defective power cable.

2.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 can ultimately dislodge the cord from the pump.

3.Discharge Port – Connect a 3-inch hose to this port. Remember to adequately support the discharge hose to avoid stress on the pump.

4.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.

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.Mechanical Seal Oil Plug – 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. DO NOT 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.Volute/Impeller – 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.
