Key Features

• Robust Cast Iron Build: Offers high structural rigidity and excellent heat dissipation, making it ideal for standard borehole conditions where durability is required.

• Efficiency: Designed for reliable, long-term performance in 3-phase power environments.

• Submersible Design: Fully sealed IP 68 construction prevents water ingress under high-pressure, deep-well applications.

• Standardized Interface: Compatible with standard 4-inch pump ends using NEMA mounting dimensions for easy assembly and replacement.

Installation and Use Notes

• Electrical Protection: A professional 3-phase control panel with thermal overload protection and single-phasing monitoring is mandatory to prevent motor burnout.

• Cooling Requirements: A minimum flow velocity of 0.08 m/s past the motor casing is required for effective cooling. A flow induction shroud must be installed in wells where natural water flow is restricted.

• Handling: Always use the motor’s lifting eyes for installation. Never suspend or support the motor assembly by the electrical power cable.

• Cable Splicing: Use only professional-grade, resin-encapsulated submersible kits to ensure a watertight seal at the power lead connection.
