Model: 10-Inch Submersible Motor
Power Output: 200 HP (150 kW)
Phase: 3-Phase
Construction: Heavy-Duty Industrial Series
SKU: TM10WL
Specifications
Motor Diameter: 10 Inches (Standard NEMA/Industrial mounting)
Voltage: 380-415 V / 50 Hz
Insulation Class: Class F (Designed for high-thermal stress and continuous operation)
Protection Rating: IP 68 (Full submersible protection)
Housing Material: High-grade Cast Iron (CI) or Stainless Steel (SS) variant (depending on specific well chemistry) with reinforced anti-corrosive 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 axial loads generated by large-diameter, high-head, multi-stage pump stacks.
Key Features
High-Capacity Industrial Duty: Engineered for 24/7 continuous water extraction, suitable for large-scale mining operations, municipal water supply, or high-volume industrial cooling.
Extreme Load Management: The robust bearing architecture is designed for the high-torque startups and sustained, high-load operation required for a 200 HP system.
Optimized Thermal Management: The high thermal mass of the housing, combined with high-capacity liquid-filled internals, ensures stable operating temperatures even under extreme work cycles.
Structural Integrity: Massive construction provides the necessary vibration dampening and structural rigidity for deep-borehole performance.
Installation and Use Notes
Electrical Infrastructure: A professional 3-phase control panel with a Soft Starter or Variable Frequency Drive (VFD) is strictly mandatory to manage high starting current and protect the motor against mechanical shock.
Cable and Voltage: Given the 150 kW load, ensure power cables are sized according to the total run length to prevent voltage drop and excessive heating.
Cooling and Flow: Maintaining a minimum flow velocity of 0.2 m/s past the motor casing is critical for heat dissipation. A flow induction shroud is required to ensure forced water movement.
Handling & Safety: At this weight class, use certified industrial hoisting equipment and lifting beams. Secure all power leads to the column pipe at regular, frequent intervals to prevent cable damage and snagging against the borehole wall.
