USK Surface Water Pump 0.75HP

The USK 0.75HP Surface Water Pump is a step up in power from the 0.5HP model, offering increased performance for domestic water supply and light commercial applications. USK is known for providing budget-friendly and functional water pumps in the Kenyan market.

Here’s a detailed overview of its features, typical applications, where to buy it in Nairobi, and price expectations:

Key Features and Specifications (Typical for USK 0.75HP Surface Water Pumps):

• Pump Type: Surface Water Pump (Peripheral Pump or Booster Pump). It sits above the water source and draws water up via suction. It’s not a submersible pump.
• Horsepower (HP): 0.75 HP.
  • Wattage: This translates to approximately 550 to 560 Watts (0.55-0.56 KW).
  • This is a good mid-range power for typical household and small-scale needs, providing better pressure and flow than a 0.5HP pump.
• Performance (General Estimates):
  • Maximum Head (Height): Significantly higher than 0.5HP, typically ranging from 35 to 48 meters. This allows it to push water to higher overhead tanks or provide better pressure for multi-story homes.
  • Maximum Suction Lift: Remains consistent with smaller surface pumps, usually around 8 meters. Optimal performance requires keeping the suction lift as short as possible.
  • Maximum Flow Rate: Increased from 0.5HP, often around 35 to 45 liters per minute (L/min), or roughly 2,100 to 2,700 liters per hour. This is sufficient for supplying water to several outlets or for more demanding garden irrigation.
• Construction:
  • Commonly features a brass impeller for durability and resistance to corrosion from clean water.
  • Often advertised with 100% copper coil motor windings for improved electrical efficiency, reduced heat generation, and longer motor lifespan compared to aluminum windings.
  • Pump body usually made of cast iron for robustness.
• Inlet/Outlet Size: Typically 1 inch x 1 inch, fitting standard plumbing connections.
• Voltage: Single-phase 220V/230V AC (50Hz), compatible with standard household electrical systems in Kenya.
• Common Model Designation: For peripheral pumps, the 0.75HP model is often referred to as “QB-70” by various manufacturers, and USK would likely have a model under this designation. Some models might be “JET” series if they are self-priming jet pumps (which also offer better suction performance).
