USK Surface Water Pump 0.75HP-QB-70

The USK Surface Water Pump 0.75HP-QB-70 is a robust and common peripheral water pump, an upgrade in power from the QB-60, designed for increased performance in water transfer applications.

Here’s a detailed overview:

Key Features and Specifications:

• Power: 0.75 HP (horsepower) or 0.55 KW (kilowatts). This increased power compared to the 0.5HP QB-60 means it can handle slightly larger volumes and/or higher pumping heights.
• Model Name: QB-70. “QB” typically denotes a peripheral or vortex pump, well-suited for clean water, providing good pressure for its size.
• Flow Rate: Generally ranges from 30 to 50 liters per minute, sometimes up to 75 L/min depending on the manufacturer and specific model (equivalent to 1800-4500 liters per hour).
• Max Head: Can reach 30 to 50 meters, indicating its ability to pump water to greater vertical distances or provide higher pressure.
• Suction Head: Typically up to 8 meters, which is the maximum vertical distance it can draw water from.
• Inlet/Outlet Size: Usually 1 inch x 1 inch.
• Voltage: 220V-240V, 50Hz (standard for Kenya and many other regions).
• Motor RPM: Around 2850-3400 RPM.
• Protection: Often comes with IP44 protection, meaning it’s protected against solid objects larger than 1mm and against splashing water from any direction.
• Materials:
  • Pump Body: Commonly cast iron, often with a special anti-rust treatment.
  • Impeller: Typically brass, known for its durability and anti-corrosion properties.
  • Motor Housing: Aluminum alloy.
  • Shaft: Carbon steel or stainless steel.
  • Mechanical Seal: Ceramic-Graphite is common.
  • Motor Winding: Copper.
