Silence is Powerful.

Stop waking up the neighbors with a noisy surface pump. The KSB Opal 15i is designed to live underwater, inside your sump, doing the heavy lifting silently and efficiently. Engineered with German technology and built in India, this 1.5 HP openwell submersible pump is the gold standard for multi-story homes and agricultural irrigation.

Unlike standard pumps that struggle with low voltage, the Opal 15i features a robust motor design that keeps running smoothly even when the power grid fluctuates (160V - 260V), ensuring your overhead tank fills up every morning without fail.

Why the Opal 15i is the Smart Choice?

  • No Priming Headaches: Since it sits submerged in water, it is always primed and ready. No more pouring mugs of water to get the suction started.
  • Voltage Warrior: Designed for Indian power conditions, it handles voltage drops down to 160V without stalling or overheating.
  • Built for Durability: Features a water-cooled, rewindable motor and a stainless steel motor body that resists corrosion and rust.
  • High Head Capacity: Capable of pushing water up to 125 feet (38 meters), making it perfect for 3-4 story buildings or long-distance irrigation.
  • Maintenance Friendly: The water-lubricated bearings and replaceable wear parts mean lower service costs over the pump's lifetime.

👨🔧 Engineer Rao’s Verdict
"The Opal 15i is my go-to recommendation for customers who have a sump tank but hate the noise of a monoblock. It’s a workhorse. The 1.5HP motor is powerful enough to fill a 1000L tank on the 3rd floor in under 20 minutes. Just remember—this is an Openwell submersible; it goes inside your open tank/sump, not inside a 6-inch borewell pipe. Pair it with a good control panel for maximum life."
