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
4.Discharge Port – Connect a
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
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.
