USK Surface Water Pump 1HP Stainless Head JETS-100

Key Features and What They Mean (USK JETS-100 1HP Stainless Head):

• Model: JETS-100. The “JET” indicates it’s a self-priming jet pump, meaning it’s capable of drawing water from a certain depth without needing manual priming every time it starts (as long as the suction line remains full). The “S” signifies Stainless Steel.
• 1HP (Horsepower): This is the motor’s power, equivalent to 0.75 kW. It’s a strong motor for domestic and light commercial applications.
• Stainless Steel Head/Pump Body: This is the key upgrade. The pump body (and often other internal components like the impeller) are made of stainless steel (often AISI 304 grade).
  • Benefits of Stainless Steel:
    • Superior Corrosion Resistance: Highly resistant to rust, oxidation, and corrosion from chlorinated water, slightly acidic/alkaline water, and general environmental factors. This is a significant advantage over cast iron.
    • Enhanced Durability & Longevity: Stainless steel is a stronger and more robust material, less prone to wear, chipping, or pitting, leading to a longer operational life for the pump.
    • Hygiene & Food Grade Compatibility: Its non-porous, smooth surface makes it less likely to harbor bacteria or mineral buildup, making it suitable for potable (drinking) water applications. Some listings explicitly state “food grade certified.”
• Typical Performance (similar to JET-100):
  • Max Head (Vertical Lift): Expect around 45 to 55 meters. This means it can generate good pressure for multi-story buildings or long-distance water transfer.
  • Max Suction Lift: Around 9 meters. Jet pumps are more efficient at operating closer to their maximum suction lift compared to peripheral pumps.
  • Max Flow Rate: Around 50 to 60 liters per minute (L/min), which is 3,000 to 3,600 liters per hour. This is a good flow rate for a busy household or small irrigation needs.
  • Inlet/Outlet Size: Typically 1 inch x 1 inch.
  • Voltage: Single-phase 220V/230V AC (50Hz).
  • Impeller: Often brass, Noryl (engineered plastic), or sometimes stainless steel for a fully stainless wet end.
  • Motor: Continuous rated duty, often with 100% copper windings and thermal overload protection.
  • IP Rating: IP44 or IP54 (splash-proof)
