USK Submersible Water Pump 0.5HP-3SDM214

The USK Submersible Water Pump 0.5HP-3SDM214 is a specific model designed for deep well applications, notable for its 3-inch diameter, making it suitable for narrower boreholes where a standard 4-inch pump might not fit.

Here’s a detailed breakdown of its features and typical specifications:

Key Features and Specifications:

• Power: 0.5 HP (horsepower) or 0.37 kW (kilowatts). This provides a good balance for domestic water supply and small-scale irrigation from wells.
• Model Name Breakdown:
  • 3SDM: This indicates a 3-inch (diameter) submersible multi-stage pump. This is crucial as it means it can be installed in boreholes with a minimum internal diameter of 3 inches (approximately 75mm). Most submersible pumps are 4-inch, so a 3-inch model is designed for narrower wells. The “multi-stage” design uses multiple impellers to build pressure and achieve higher head.
  • 2/14 (or 214): The “2” typically refers to a specific flow rate series (e.g., around 2 m³/h or 33 L/min at optimal efficiency), and the “14” indicates the number of impellers or stages within the pump. More stages generally result in a higher maximum head.
• Submersible Design: The entire pump (motor and pump end) is designed to be fully submerged in the water source.
  • Silent Operation: The water dampens noise, making it very quiet.
  • No Priming Needed: It’s always primed as it operates within the water.
  • Efficient Motor Cooling: The surrounding water cools the motor, preventing overheating, which is vital for continuous operation in deep wells.
• Max Head (Maximum Delivery): For a 0.5HP 3SDM214, the maximum head is typically around 80 to 90 meters (approximately 260-295 feet). This high head capacity for a 0.5HP pump is a direct result of having 14 stages, enabling it to lift water from significant depths.
• Rated Flow Rate: The flow rate will vary with the head. At its optimal efficiency point, it might deliver around 20-40 liters per minute (L/min), or 1.2 to 2.4 cubic meters per hour (m³/h). The flow decreases as the head increases.
