USK 4SDM310 Submersible Water Pump 0.75HP

The USK 4SDM310 Submersible Water Pump 0.75HP is a mid-range submersible pump designed for deeper boreholes or wells, offering increased performance compared to the 0.5HP model. The “4SDM310” model number gives precise insights into its design and capabilities.

Key Specifications and What They Mean:

• USK 4SDM310:

  • “4”: This indicates the diameter of the pump in inches, meaning it’s designed for boreholes or wells with a minimum casing diameter of 4 inches (approx. 100mm). This is a very common size for domestic, small-scale agricultural, and light industrial boreholes.
  • “SDM”: Denotes a Submersible Deep Well Multi-stage pump. Multi-stage pumps have multiple impellers in series, enabling them to generate very high head (pressure) for pumping water from significant depths.
  • “3”: Often indicates the nominal flow rate, likely 3 cubic meters per hour (3m³/h), or 50 liters per minute, at a specific head.
  • “10”: This is critical. It typically indicates the number of impellers (10 stages) within the pump. More impellers mean the pump can generate higher head (push water higher) for a given motor size.

• Submersible Water Pump: The entire pump and motor assembly are designed to be fully immersed in the water during operation.

  • Advantages (reiterated): No priming needed, quiet operation, very efficient for deep water sources as it pushes rather than pulls, less prone to cavitation, and no suction lift limitations.

• 0.75HP (Horsepower): This indicates the motor’s power output.

  • In Watts/Kilowatts: 0.75 HP is equivalent to approximately 550 Watts (0.55 KW). This power level,
