Model: 6-Inch Submersible Motor
Power Output: 15 HP (11 kW)
Phase: 3-Phase
Construction: Water-Filled / Oil-Filled (Cooling variant) SKU: ACSONS-MOTOR-6IN-15HP-3PH-SSJKT
Specifications
Motor Diameter: 6 Inches (Standard NEMA mounting)
Voltage: 380-415 V / 50 Hz
Insulation Class: Class F (Engineered for high-temperature stability in deep-well environments)
Protection Rating: IP 68 (Certified for continuous deep-well submersion)
Housing Material: High-grade, corrosion-resistant stainless steel (AISI 304/316)
Shaft Material: High-strength, stress-relieved stainless steel
Bearing System: Heavy-duty, self-aligning Kingsbury-type thrust bearings to support high axial down-thrust loads from heavy multi-stage pump ends.
Cooling System: Optimized internal fluid circulation for heat dissipation during heavy-duty cycles.
Key Features
High-Torque Performance: Designed for a smooth, reliable startup, minimizing mechanical stress on the pump assembly.
Robust Sealing: Equipped with advanced multi-stage mechanical seals to prevent water contamination of the internal windings.
Durability: Built to withstand the harsh conditions of deep boreholes, including sand resistance and varying groundwater chemical compositions.
Precision Engineering: Standardized interface ensures a perfect, leak-free seal when coupled with 6-inch pump ends.
Installation and Use Notes
Electrical Connection (~SSJKT): This unit includes a Professional Submersible Splice/Jointing Kit. The resin-filling process is critical: ensure the joint is entirely free of air pockets to prevent moisture ingress. Use only the provided kit to maintain the motor's IP 68 integrity.
Control Panel Requirements: A 3-phase control panel with Star-Delta or Soft Starter is highly recommended for a 15 HP motor to prevent peak current spikes and mechanical shock to the system. Thermal overload protection is non-negotiable.
Cooling and Flow: To prevent overheating, ensure a minimum flow velocity of 0.15 m/s past the motor casing. If installing in a wide-diameter well, a flow induction shroud must be used to force water across the motor body.
Cable Integrity: Never use the power cable for lifting or lowering. Use a certified, high-strength safety rope or steel cable. Ensure the cable is secured to the piping at regular intervals to prevent damage during installation.
