USK 3SDM214 Submersible Water Pump 0.5HP

The USK 3SDM214 Submersible Water Pump 0.5HP is a specialized submersible pump, distinct from the more common 4-inch (4SDM) models. The key differentiator here is the “3” in “3SDM,” indicating its narrower diameter.

Key Specifications and What They Mean:

• USK 3SDM214:

  • “3”: This is the most important part. It indicates the diameter of the pump in inches, meaning it’s designed for narrower boreholes or wells, specifically those with a minimum casing diameter of 3 inches (approximately 75mm or 80mm). This is crucial, as many boreholes are 4 inches or wider, but some older or specialized wells might be narrower.
  • “SDM”: Denotes a Submersible Deep Well Multi-stage pump. This design uses multiple impellers in series to generate high head (pressure) necessary for pumping water from significant depths.
  • “2”: Often indicates a nominal flow rate, potentially 2 cubic meters per hour (2m³/h) or around 33 liters per minute, at a specific head.
  • “14”: This number typically signifies the number of impellers (14 stages) within the pump. A higher number of impellers directly contributes to the pump’s ability to generate more head and overcome greater vertical distances, especially important for a pump with a smaller diameter.

• Submersible Water Pump: The entire pump and motor unit are designed to be fully immersed in the water within the well or borehole during operation.

  • Key Advantages: No priming required, quiet operation, highly efficient for deep lifts (pushes water up), less prone to cavitation, and overcomes suction lift limitations.

• 0.5HP (Horsepower): This indicates the motor’s power output.

  • In Watts/Kilowatts: 0.5 HP is equivalent to approximately 370 Watts (0.37 KW). For a submersible pump, especially one with 14 stages, even 0.5HP can achieve impressive depths.
