SKU: ACSONS-MOTOR-6IN-15HP-3PH-CI-VCI
Specifications
Motor Diameter: 6 Inches (Standard NEMA mounting)
Voltage: 380-415 V / 50 Hz
Insulation Class: Class F (Engineered for high-temperature stability)
Protection Rating: IP 68 (Submersible)
Housing Material: Industrial-Grade Cast Iron (CI) with epoxy anti-corrosive coating
Shaft Material: Hardened Stainless Steel
Bearing System: Heavy-duty, self-aligning axial thrust bearings to manage high down-thrust loads from heavy multi-stage pump ends.
Sand Protection: Integrated V-CI (V-Type Sand Shield) system, designed to deflect abrasive particles and protect the mechanical seals in sediment-prone borehole environments.
Key Features
Durable Cast Iron Construction: The robust Cast Iron (CI) housing provides exceptional structural stability and resistance to external physical stress in rough borehole conditions.
V-Type Sand Shield (V-CI): This specialized shield prevents sand/silt buildup around the seal area, significantly increasing the reliability and lifespan of the motor in harsh, sandy water.
Heat Dissipation: Cast iron offers excellent thermal mass, which, combined with the internal liquid-filled design, ensures consistent performance during prolonged, heavy-duty operation.
Standardized Mounting: The 6-inch NEMA-standard interface ensures a precise and secure fit with various pump ends.
Installation and Use Notes
Corrosion Protection: While the CI housing is treated with anti-corrosive epoxy, it is intended for use in environments where the water chemistry is compatible with cast iron. In highly acidic or extremely saline water, stainless steel (SS) variants are recommended.
Electrical Protection: A professional 3-phase control panel with Star-Delta or Soft Starter is strongly recommended for a 15 HP motor to manage starting torque and current spikes. Thermal overload and phase-imbalance protection are essential.
Cooling and Flow: A minimum flow velocity of 0.15 m/s past the motor casing is required. Use a flow induction shroud if the borehole diameter is large to ensure the water flows along the casing for optimal heat exchange.
Handling: Use professional lifting equipment and the motor’s built-in lifting eyes. Secure the motor lead to the column pipe every 3 meters to prevent damage during descent.
