USK Submersible Water Pump 0.75HP 4SDM310

The “USK Submersible Water Pump 0.75HP 4SDM310” is a very specific model, and the inclusion of “4SDM310” is helpful as it often refers to the pump’s series and design, indicating its well diameter and number of impellers or stages.

Based on search results, the 4SDM310 series typically means a 4-inch diameter pump.

Here’s a detailed breakdown of this specific model:

Key Features and Specifications (USK 0.75HP 4SDM310 Submersible Water Pump):

• Pump Type: Submersible Borehole Pump. Designed to be fully immersed in a well or borehole.
• Horsepower (HP): 0.75 HP.
  • Wattage: 0.55 kW.
• Model Series: 4SDM310.
  • “4” generally indicates it’s designed for a 4-inch (or larger) borehole casing.
  • “SDM” often refers to a multi-stage deep well submersible pump.
  • “310” likely indicates the number of impellers/stages or a specific head/flow curve for this power.
• Performance:
  • Maximum Head (Vertical Lift): The key specification for this model is 56 meters. Some listings also show a similar model with a 62-meter head. This is the maximum height the pump can push water from its submerged position.
  • Flow Rate: Ranges from 20 liters/min (L/min) at higher heads to 69 liters/min (L/min) at lower heads. This translates to roughly 1.2 to 4.14 cubic meters per hour (m³/h). The flow rate decreases as the head increases.
• Construction:
  • Stainless Steel Construction: Explicitly mentioned in descriptions for the 4SDM310, enhancing durability and corrosion resistance in submerged conditions. This includes the body and possibly some internal components.
  • Impellers: Often “sand-crushing impellers” (likely engineered plastic or stainless steel) designed for durability, even with some sand content in the water.
  • Motor Windings: Generally 100% copper coil windings for efficiency and longevity.
• Voltage: Single-phase 220V-240V AC (50Hz), compatible with standard Kenyan household electricity.
• Control Box: Comes with an external control box for starting and motor protection.
• Cable: Includes a pre-attached electrical cable, typically suitable for the pump’s maximum head (e.g., 50 meters or more).
