USK Jet-100 Surface Pump 1HP

The USK Jet-100 Surface Pump 1HP is a popular and robust choice in Kenya for various water pumping needs, particularly where higher pressure and self-priming capability are desired. As a “Jet” pump, it functions differently from the “QB” (peripheral) series, making it suitable for a broader range of suction conditions, including slightly deeper wells.

Key Specifications and What They Mean:

• USK Jet-100: This model designation indicates it’s a “Jet” type pump. Jet pumps use a venturi system within the pump housing (or in the well for deep well versions) to create a vacuum, allowing them to draw water from greater depths compared to standard centrifugal or peripheral pumps.
• Surface Pump: This means the pump is designed to be installed above ground, drawing water via a suction pipe from a well, tank, or other water source. It is not designed to be submerged in water.
• 1HP (Horsepower): This is a significant power rating for domestic and light commercial applications.
  • In Watts/Kilowatts: 1 HP is equivalent to approximately 750 Watts (0.75 KW). This motor size provides ample power for demanding water transfer and pressure boosting.

Typical Performance Specifications (based on common Jet-100 1HP pumps in Kenya):

• Maximum Head (Height): Often ranges from 45 to 55 meters. This indicates the maximum vertical distance the pump can push water. This is a very good head for multi-story buildings or pushing water over long distances.
• Maximum Suction Lift: A key advantage of jet pumps. While atmospheric pressure limits direct suction to around 9-10 meters for shallow well jet pumps, the Jet-100 (being a shallow well jet pump typically) can effectively draw from 8 to 9 meters depth. Some sources might suggest they are “ideal for deep wells,” but for a standard surface JET-100, this refers to its capability to handle slightly gassier water or fluctuating water levels better than a peripheral pump, rather than truly deep wells (which would require a submersible or a deep well jet pump with an ejector assembly down the well).
• Maximum Flow Rate: Generally ranges from 50 to 60 liters per minute (L/min), or 3,000 to 3,600 liters per hour. This is a robust flow rate suitable for supplying multiple outlets simultaneously or quickly filling large tanks. Jumia lists 3,180 liters per hour (53 L/min) for the USK Jet-100 1HP.
• Inlet/Outlet Size: Commonly 1 inch x 1 inch, fitting standard plumbing connections.
