USK Surface Water Pump 1HP JET-100

Key Features and Specifications:

• Power: 1.0 HP (horsepower) or 0.75 KW (kilowatts). This is a significant step up from the 0.5HP and 0.75HP QB models, offering greater flow and head capacity.
• Model Name: JET-100. The “JET” indicates its self-priming jet pump design, which uses a Venturi system to create suction.
• Self-Priming Capability: This is a key distinguishing feature. The pump can automatically draw water and prime itself, eliminating the need for manual filling of the suction line in many cases. This is crucial for applications like drawing water from wells, boreholes, or rainwater tanks.
• Flow Rate: Typically ranges from 50 to 60 liters per minute (L/min) or up to 3,180 liters per hour (L/hr).
• Max Head: Can reach 43 to 45 meters, providing strong pressure for multi-storey buildings or extended irrigation systems.
• Suction Head: Up to 8 or 9 meters, allowing it to draw water from relatively deep sources.
• Inlet/Outlet Size: Usually 1 inch x 1 inch.
• Voltage: 220V-240V, 50Hz (standard for Kenya).
• Motor RPM: Around 2850-3400 RPM.
• Protection: Commonly features IP44 protection (splash-proof) and often includes built-in thermal protection to prevent motor overheating.
• Materials:
  • Pump Body: Often made of robust cast iron for durability and corrosion resistance.
  • Impeller: Typically brass or technopolymer (PPO/Noryl), chosen for efficiency and resistance to corrosion.
  • Motor Housing: Aluminum alloy.
  • Shaft: Carbon steel or stainless steel.
  • Mechanical Seal: Usually ceramic and graphite for reliable sealing.
  • Motor Winding: Copper.
