Model: 6-Inch Submersible Motor
Power Output: 20 HP (15 kW)
Phase: 3-Phase Construction: Stainless Steel (SS) Housing with V-Type Sand Shield (V-SS)
SKU: ACSONS-MOTOR-6IN-20HP-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 heavy-duty cycles)
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 high down-thrust loads of 20 HP 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 protective barrier that prevents sediment accumulation around the shaft seal, essential for 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.
High-Torque Performance: Precision-engineered windings and liquid-filled cooling ensure the motor maintains steady output and efficient operation at its 20 HP rating.
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: Regularly inspect the V-SS area during pump maintenance cycles to ensure it remains clear of debris and is functioning as designed.
Electrical Protection: A professional 3-phase control panel with Star-Delta or Soft Starter is mandatory for a 20 HP unit. Ensure that overload protection and phase-monitoring relays are accurately calibrated to the motor’s specific Full Load Amperage (FLA).
Cooling and Flow: Maintaining a minimum flow velocity of 0.15 m/s past the motor casing is mandatory. If the borehole is significantly larger than the 6-inch motor body, a flow induction shroud must be installed to force cooling water over the stainless steel casing.
Handling & Safety: Given the weight of this 20 HP unit, use only the designated lifting eyes with certified industrial lifting equipment. Secure the power cable to the column pipe at frequent intervals to prevent borehole wall abrasion.
