Insulation Class: Class B (Standard thermal insulation)
Protection Rating: IP 68 (Full submersible protection)
Cooling/Lubrication: Oil-filled design using high-dielectric, non-toxic food-grade mineral oil for optimal cooling and bearing lubrication.
Shaft Material: Hardened stainless steel.
Bearing System: Industrial-grade radial and thrust bearings designed for reliable single-phase performance.
Key Features
Oil-Filled Advantage: Provides excellent heat dissipation and protects internal components from corrosion and water ingress, ensuring a longer service life in standard domestic or light-agricultural wells.
Single-Phase Reliability: Engineered for standard residential electrical grids, making it easy to install without 3-phase power infrastructure.
Pressure Equalization: Features a built-in diaphragm to equalize internal pressure with the well environment, preventing seal failure.
Standardized Interface: Compatible with industry-standard 4-inch NEMA pump ends.
Installation and Use Notes
Electrical Control: Must be used with a compatible Control Box containing the necessary start and run capacitors for single-phase torque requirements.
Cooling Requirement: A minimum flow velocity of 0.08 m/s past the motor casing is necessary to ensure adequate heat dissipation. A flow induction shroud is recommended if the borehole diameter is significantly larger than the motor.
Handling: Use only the motor's dedicated lifting eyes. Never support the pump-motor assembly by the power cable, as this can damage the cable entry seal.
Cable Connection: Ensure all cable splices are completed using a professional-grade, resin-encapsulated submersible kit to maintain the IP 68 rating.
