Installation and Use:

This high-capacity 20HP openwell submersible pump is built to operate completely underwater, eliminating priming issues and suction lift limitations. Designed for open wells, underground storage tanks, and rivers, its heavy-duty three-phase motor is cooled efficiently by the surrounding water. Ensure the pump rests on a flat, stable foundation or base plate to minimize underwater vibration. Always utilize a suitable starter panel containing phase-failure protection, dry-run protection, and a thermal overload relay to shield the motor windings from electrical damage.
