USK Submersible Water Pump 1HP 3SDM227

The “USK Submersible Water Pump 1HP 3SDM227” is a very specific and powerful model of a submersible pump, primarily designed for deep borehole applications. The model code provides crucial details about its construction and performance.

Here’s a breakdown of what each part of the name signifies:

• USK: The brand of the pump. USK is known for producing a range of water pumps, often aiming for a balance of functionality and affordability.
• Submersible Water Pump: This means the pump is designed to be fully immersed in the water source (e.g., inside a borehole, deep well, or large reservoir). Operating underwater, it pushes water upwards, eliminating priming issues and benefiting from water-cooling for the motor.
• 1HP (Horsepower): The motor’s power output. 1 HP is equivalent to approximately 750 Watts (0.75 kW). This is a robust power rating for submersible pumps, making it suitable for significant water lifting and supply needs in residential, small-scale commercial, or agricultural settings.
• 3SDM227: This is the critical model code that provides specific details about the pump’s design:
  • 3: Refers to the diameter of the pump in inches. This means the pump is designed to fit into a 3-inch diameter borehole casing or larger. This is a common size for narrower boreholes where space is limited.
  • SDM: Indicates the type of pump and motor. “SDM” commonly stands for Stainless Steel Deep Well Motor, implying that both the motor casing and the pump’s hydraulic parts (casing) are constructed from stainless steel. This material provides excellent corrosion resistance and durability, which is essential for long-term use in submerged environments. It also signifies that it’s a multi-stage centrifugal pump, utilizing a series of impellers to build pressure and lift water from great depths.
  • 2: This number typically represents the approximate flow rate in cubic meters per hour (m3/h) at a specific head, or it might refer to the series number for flow characteristics.
  • 27: Refers to the number of impellers (stages) in the pump. A higher number of impellers allows the pump to generate significantly more pressure (head) from the same motor size. 27 impellers for a 1HP pump is a very high number, indicating its capability for extremely deep wells.
