Figure 2. Submersible Pump Components

Figure 2 shows the location of the basic components, for the 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.Mechanical Seal – 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.

3.Electric Motor – These pumps use either a 230 VAC or 460 VAC, 3Ø, 60 Hz electric motor. Reference Table 1. for the electric motor for your model pump. Consult with a licensed electrician before connecting motor to a power source. Observe all city and local safety codes.

4.Nameplate – Provides vital electrical pump information. Always read this tag before applying power to the pump.

5.Discharge Port – Connect a 4-inch hose to this port (NPT 4" threads). Remember to adequately support the discharge hose to avoid stress on the pump.

6.Lifting Handle – Attach a suitable lifting device to this handle capable of lifting about 200 lbs. (91 kg) NEVER lift the pump by its power cord.

7.AC Power Cable – These pumps are supplied with a 33 ft. (10 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.

8.Power Cable Clamp – Attaches power cable to pump to prevent movement.

9.Impeller – Impellers are constructed of chrome steel to minimize wear and prolong service life.

10.Mechanical Seal Oil Plug – Remove this plug to check and add ISO VG32 lubrication oil, Mobile DTE 24, turbine oil 90 or equivalent to the oil chamber. This oil protects the mechanical seal. Oil chamber should be full enough to cover seal spring.

11.Discharge Port – Connect a 6-inch hose to this port (NPT 6" threads). Remember to adequately support the discharge hose to avoid stress on the pump.

12.Eye Bolts – Attach a suitable lifting device to this handle capable of lifting about 300 lbs. (136 kg). 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.
