Figure 2. Submersible Pump Components

Figure 2 shows the location of the basic components, for the ST-4125D and ST-6125D 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. For dewatering purposes, always place the strainer base on a platform.

2.Volute/Impeller – Impellers are constructed of cast ductile iron to minimize wear and prolong service life.

3.Electric Motor – The ST-4125D pump utilizes a 60 Hz, three-phase, 230/460 VAC, 10 HP electric motor and the ST-6125D pump utilizes a 60 Hz, three-phase, 230/ 460 VAC, 15 HP electric motor. Consult with a licensed electrician before connecting motor to a power source. Observe all city and local safety codes.

4.Discharge Port – Connect a 4-inch hose (ST-4125D) or 6-inch hose (ST-6125D) to this port. Remember to adequately support the discharge hose to avoid stress on the pump.

5. AC Power Cable – These pumps are supplied with a 50 ft. (15.2 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.

6.Eye Bolts – Always lift the submersible pump by the eye bolts using a chain and lifting device capable of lifting about 400 lbs. NEVER lift the pump by its power cord! 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.Mechanical Seal Oil – 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.

8.Mechanical Seal Oil 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.
