Model: 6-Inch Submersible Motor
Power Output: 25 HP (18.5 kW)
Phase: 3-Phase
Construction: Stainless Steel (SS) Housing with V-Type Sand Shield (V-SS)
SKU: ACSONS-MOTOR-6IN-25HP-3PH-SS-VSS
Specifications
Motor Diameter: 6 Inches (Standard NEMA mounting)
Voltage: 380-415 V / 50 Hz
Insulation Class: Class F (High-thermal capacity for sustained industrial loads)
Protection Rating: IP 68 (Full submersible protection)
Housing Material: AISI 304 High-Grade Stainless Steel
Shaft Material: Hardened Stainless Steel for maximum torsion resistance
Bearing System: Upgraded, heavy-duty axial thrust bearings engineered to manage the significant down-thrust loads of 25 HP multi-stage pump assemblies.
Sand Protection: Integrated V-SS (V-Type Sand Shield) system, designed to effectively deflect abrasives and protect the primary mechanical seals from wear in sandy or silt-laden boreholes.
Key Features
Advanced Sand Defense: The "V-SS" configuration creates a durable, protective barrier that prevents sediment accumulation around the shaft seal, significantly extending motor life in challenging, deep-well environments.
Corrosion-Resistant SS Body: Constructed entirely from high-grade stainless steel, this motor is built to withstand aggressive groundwater chemistries and long-term submersion without compromising structural integrity.
High-Performance Output: Precision-wound internal components and liquid-filled cooling ensure the motor maintains steady, efficient output at its 25 HP rating, even during extended run-times.
Structural Integrity: Robust NEMA-standard interface ensures a secure, leak-proof coupling with compatible 6-inch high-performance pump ends.
Installation and Use Notes
Sand Shield Maintenance: During routine pump servicing, inspect the V-SS area to ensure it remains clear of debris and continues to function as the primary abrasive barrier for the motor.
Electrical Protection: A professional 3-phase control panel with Star-Delta or Soft Starter is mandatory for a 25 HP unit. Ensure that thermal overload and phase-monitoring relays are strictly calibrated to the motor’s Full Load Amperage (FLA) to prevent winding damage.
Cooling and Flow: Maintaining a minimum flow velocity of 0.15 m/s past the motor casing is mandatory for heat dissipation. If the borehole diameter is significantly larger than the 6-inch motor body, a flow induction shroud must be installed.
Handling & Safety: Given the substantial weight of this 25 HP unit, use only the designated lifting eyes with certified industrial crane or winching equipment. Secure the power cable to the column pipe at frequent intervals (every 3 meters) to prevent borehole wall abrasion.
