USK 4SDM313 Submersible Water Pump 1HP

The USK 4SDM310 Submersible Water Pump 1HP is a powerful and popular option for various water supply needs from deep sources in Kenya. This model significantly increases the pumping capability over the 0.5HP and 0.75HP versions, making it suitable for deeper boreholes and higher flow requirements.

Here’s a comprehensive overview:

Key Specifications and What They Mean:

• USK 4SDM310:

  • “4”: Indicates the diameter of the pump in inches, meaning it’s designed to fit into boreholes or wells with a minimum casing diameter of 4 inches (approximately 100mm). This is the standard size for many domestic and agricultural boreholes.
  • “SDM”: Stands for Submersible Deep Well Multi-stage pump. The multi-stage design means it has several impellers stacked in series, enabling it to achieve very high head (pressure) to push water from significant depths.
  • “3”: Often relates to a nominal flow rate, potentially 3 cubic meters per hour (3m³/h) or 50 liters per minute, at a specific operating point.
  • “10”: This is crucial. It typically denotes the number of impellers (10 stages) within the pump. A higher number of impellers directly correlates to the pump’s ability to generate more head and overcome greater vertical distances.

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

  • Key Advantages:
    • No priming required: Operates directly within the water.
    • Quiet operation: Water muffles motor noise.
    • Highly efficient for deep lifts: Pushes water up rather than pulling, which is more energy-efficient for high heads.
    • Less prone to cavitation: Water pressure helps prevent air pockets.
    • Overcomes suction lift limitations: Can pump from depths far beyond what surface pumps can manage.

• 1HP (Horsepower): This indicates the motor’s power output.

  • In Watts/Kilowatts: 1 HP is equivalent to approximately 750 Watts (0.75 KW). This power, combined with the multi-stage (10 impeller) design, allows for impressive depth and flow capabilities.
