Phase: 3-Phase
Construction: Cast Iron (CI) Housing with V-Type Sand Shield (V-CI)
SKU: ACSONS-MOTOR-9IN-125HP-3PH-CI-VCI
Specifications
Motor Diameter: 9 Inches (Standard NEMA/Industrial mounting)
Voltage: 380-415 V / 50 Hz
Insulation Class: Class F (High-thermal capacity for extreme industrial loads)
Protection Rating: IP 68 (Full submersible protection)
Housing Material: Industrial-Grade Cast Iron (CI) with multi-stage anti-corrosive epoxy coating
Shaft Material: High-tensile, hardened stainless steel
Bearing System: Extra-heavy-duty, self-aligning Kingsbury-type axial thrust bearings, specifically engineered to manage the extreme downward thrust loads generated by large-diameter, high-head, multi-stage pump stacks.
Sand Protection: Integrated V-CI (V-Type Sand Shield) system, engineered to deflect abrasive particles and provide a robust barrier for the mechanical seal assembly in high-sediment borehole environments.
Key Features
Heavy-Industrial Reliability: Engineered for continuous, 24/7 high-capacity water extraction in major municipal, mining, or large-scale agricultural infrastructure projects.
Structural Stability: The massive cast iron housing offers exceptional structural rigidity and vibration dampening, ensuring stability during the high-torque startups and sustained operation required for 125 HP.
Advanced Sand Management (V-CI): This high-performance shield design is vital for preventing sediment buildup around the motor-pump interface, significantly reducing wear in deep, abrasive wells.
Thermal Management: The high thermal mass of the cast iron body, integrated with a high-capacity internal liquid-filled system, ensures superior heat dissipation during heavy-duty operation.
Installation and Use Notes
Electrical Infrastructure: A professional 3-phase control panel with Soft Starter or Variable Frequency Drive (VFD) is mandatory to manage the significant starting current and prevent mechanical shock. Ensure cable sizing is strictly calculated to account for total run length and prevent excessive voltage drop.
Environmental Compatibility: Best suited for neutral, non-corrosive water environments. In highly saline or aggressive water conditions, the Stainless Steel (V-SS) series is recommended.
Cooling and Flow: Maintaining a minimum flow velocity of 0.2 m/s (due to the larger motor diameter) past the casing is critical. A flow induction shroud is strictly required in most installations to guarantee adequate heat exchange.
Handling & Safety: Given the substantial weight of a 125 HP assembly, use professional-grade hoisting equipment and certified lifting beams. Secure all power leads to the column pipe at regular 2-meter intervals to prevent snagging or cable damage during installation.
