Model: 6-Inch Submersible Motor
Power Output: 40 HP (30 kW)
Phase: 3-Phase
Construction: Heavy-Duty Industrial Series
SKU: TM6WL-40HP
Specifications
Motor Diameter: 6 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: Industrial-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 substantial axial loads generated by 6-inch high-head, multi-stage pump stacks.
Key Features
High-Capacity Performance: Engineered for continuous, heavy-duty water extraction, ideal for agricultural irrigation, industrial water supply, and municipal pumping systems.
Robust Construction: The reinforced housing provides superior structural rigidity and vibration dampening, ensuring stability during high-torque startup and sustained operation.
Thermal Management: Optimized liquid-filled internal architecture combined with the high thermal mass of the housing ensures efficient heat dissipation during sustained 30 kW operations.
Seal Protection: Equipped with a high-performance mechanical seal assembly designed to withstand deep-well pressures and abrasive borehole conditions.
Installation and Use Notes
Electrical Infrastructure: A professional 3-phase control panel with a Star-Delta or Soft Starter is mandatory to manage the high startup current and protect the motor from mechanical stress.
Cable Sizing: Given the 30 kW power load, ensure power cables are sized correctly for the specific borehole depth and distance to the control panel to prevent excessive voltage drop.
Cooling and Flow: A minimum flow velocity of 0.15 m/s past the motor casing is critical for heat dissipation. If the borehole diameter is significantly larger than the 6-inch motor, a flow induction shroud is required to ensure forced water circulation.
Handling & Safety: Use professional-grade hoisting equipment and the designated lifting eyes for installation. Secure the motor leads to the column pipe at regular 3-meter intervals to prevent snagging or cable abrasion against the borehole wall.
