USK Surface Water Pump 0.5HP QB-60

Key Specifications and What They Mean:

• USK QB-60: This is the model designation. “QB-60” typically refers to a peripheral or regenerative pump with a brass impeller. These pumps are known for their ability to generate relatively high head (pressure) at a lower flow rate compared to centrifugal pumps of similar horsepower.
• Surface Water Pump: This indicates that the pump is designed to be placed above the water source. It draws water up through a suction pipe. It is NOT a submersible pump (which goes directly into the water).
• 0.5HP (Horsepower): This is the motor’s power output. In Watts, 0.5 HP is approximately 370 Watts (0.37 KW). This signifies a small to medium-sized motor, well-suited for household needs.

Typical Performance Specifications (based on common QB-60 0.5HP pumps):

• Maximum Head (Vertical Lift): Typically around 28 to 40 meters. This is the maximum vertical distance the pump can push water upwards. A common specification cited for the USK QB-60 is 28 meters.
• Maximum Suction Lift: Usually around 8 meters. This is the maximum vertical distance the pump can draw water up from the source to the pump’s inlet. For optimal performance and to avoid cavitation, it’s always best to keep the suction lift as short as possible.
• Maximum Flow Rate: Around 27 to 35 liters per minute (L/min), or roughly 1,620 to 2,100 liters per hour. This is a moderate flow rate, suitable for supplying water to a single household or for small garden irrigation.
• Inlet/Outlet Size: Commonly 1 inch x 1 inch. This is a standard size for household plumbing connections.
• Voltage: Single-phase 220V/230V AC (50Hz), making it compatible with standard household electrical outlets in Kenya.
• Motor Speed: Around 2850 RPM.
