USK Surface Water Pump 0.75HP QB-70

Key Specifications and What They Mean:

• USK QB-70: This is the model designation. Like the QB-60, the “QB” series typically refers to peripheral or regenerative pumps, which are known for producing higher pressure (head) relative to their flow rate.
• Surface Water Pump: This means it’s designed to operate above the water source, drawing water up via a suction pipe. It is not designed to be submerged.
• 0.75HP (Horsepower): This is the motor’s power output. 0.75 HP converts to approximately 550 Watts (0.55 KW). This increased power over the 0.5HP QB-60 allows for greater flow and/or head.

Typical Performance Specifications (based on common QB-70 0.75HP pumps):

• Maximum Head (Vertical Lift): Typically around 40 to 50 meters. This is a significant increase from the QB-60, allowing it to push water to higher floors or over longer distances. A common specification cited for the QB-70 is 40 to 50 meters.
• Maximum Suction Lift: Usually remains around 8 meters. While the pump can push higher, its ability to draw water up from the source is limited by atmospheric pressure. Always keep the suction lift as short as possible for optimal performance.
• Maximum Flow Rate: Around 35 to 45 liters per minute (L/min), or roughly 2,100 to 2,700 liters per hour. This offers a noticeable increase in water delivery compared to the 0.5HP model.
• Inlet/Outlet Size: Commonly 1 inch x 1 inch. This is a standard size for household plumbing.
• Voltage: Single-phase 220V/230V AC (50Hz), compatible with standard household electrical outlets in Kenya.
• Motor Speed: Around 2850 RPM.
• Construction:
  • Pump Body: Often cast iron.
  • Impeller: Typically brass, with peripheral vanes.
  • Motor Shaft: Often stainless steel.
  • Mechanical Seal: Ceramic-graphite.
  • Protection: IP44 (splash-proof).

Common Applications:

• Larger Households: Ideal for providing water to multi-story homes or those with multiple bathrooms where higher pressure is desired.
• Medium-Sized Garden Irrigation: Can handle sprinklers or drip irrigation for larger gardens than the QB-60.
• Boosting Municipal Water Pressure: More effective at boosting low pressure for consistent supply.
• Water Transfer: Efficiently moving larger volumes of clean water between storage tanks.
• Small Farms/Greenhouses: Suitable for limited irrigation needs.
