USK Surface Water Pump JET-100 1HP

The “USK Surface Pump JET-100 1HP” is a very common and popular type of self-priming jet pump designed for boosting water pressure and transferring water, particularly from shallow wells or reservoirs where air might be present in the suction line. The “JET-100” refers to its model series, and “1HP” indicates its motor power.

Here’s a detailed breakdown of its specifications and common applications:

• USK JET-100: This model name signifies a “jet pump” which is a type of centrifugal pump with an additional ejector system. This system allows the pump to self-prime, meaning it can draw water up even if there’s air in the suction pipe, and it’s generally good at handling some air or gas mixed with the water. “JET-100” is a standard designation for a 1HP jet pump across various manufacturers.
• Surface Water Pump: This means the pump is designed to be installed above the water source. It draws water up through a suction pipe.
• 1HP (Horsepower): This is the motor’s power output.
  • In Watts: 1 HP is equivalent to approximately 750 Watts (0.75 kW). This is a robust power level for domestic and light commercial water pumping needs, offering significantly better performance than 0.5HP or 0.75HP peripheral pumps.USK Surface Water Pump JET-100 1HP

Typical Performance Specifications (based on USK JET-100 1HP and similar models):

• Maximum Head (Height): A 1HP jet pump typically offers a high head (pressure). You can expect a maximum head of around 45 to 52 meters. This makes it highly effective for boosting pressure to multiple taps, pushing water to elevated tanks in multi-story buildings, or for more demanding irrigation.
• Maximum Suction Lift: Jet pumps generally have a good suction lift capability, often around 9 meters. They are particularly well-suited for drawing water from shallow wells.
• Maximum Flow Rate: The flow rate will be considerably higher than smaller peripheral pumps. For a 1HP JET-100, expect a flow rate of approximately 3,180 liters per hour (53 L/min) or even up to 3.5 cubic meters per hour (3500 L/hr) as per some specifications. This is a strong flow rate for household supply and medium-sized irrigation.
• Inlet/Outlet Size: Commonly 1 inch x 1 inch, suitable for standard plumbing connections.
• Voltage: Single-phase 220V-240V AC (50Hz), compatible with standard household electrical systems in Kenya.
• Impeller Material: Often brass or bronze for durability and corrosion resistance.
• Motor Winding: Typically 100% copper winding for efficiency and longevity.
• Construction: Often features a cast iron pump body for durability and thermal protection for safety (IP44 rated motor is common).

Common Applications:

• Boosting Water Pressure: Excellent for increasing water pressure in residential homes, apartments, and small commercial buildings, especially where municipal supply is inadequate.
• Water Supply from Shallow Wells/Boreholes: Ideal for drawing water from wells, cisterns, or boreholes up to 9 meters deep.
