ST-1500 SERIES SUB. PUMP — COMPONENTS

Figure 2. Submersible Pump Components

Figures 2 shows the location of the basic components, for the ST-1500 series 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. DO NOT pump large objects or debris with this pump.This pump is for pumping water only. For de-watering purposes, always place the strainer base on a platform.

2.Volute/Impeller – Impellers are constructed of high-chrome ductile iron to minimizes wear and prolong service life.

3.Electric Motor – The ST-1503A submersible pump utilizes a 60 Hz, single-phase, 115 VAC, 0.5 HP electric motor.The ST-1503CUL submersible pump utilizes a 60 Hz, single- phase, 115 VAC, 0.33 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 2-inch (ST-1503A) or 1.5- inch (ST-1503CUL) hose to this port. Remember to adequately support the discharge hose to avoid stress on the pump.

5.AC Power Cable – This unit is supplied with a 25 ft. (7.6 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.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 ultimately the cord will become dislodged from the pump.

7.Thermal Overload Protection – This pump is equipped with a thermal overload protection device that will shutdown the motor in the event of high operating temperatures.The motor will automatically restart once the temperature returns to an acceptable operating temperature.

8.Mechanical Oil 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.

9.Mechanical Oil Seal 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.
