Non-Contact Magnetic Coupling
Magnetic couplings offer a non-contact transfer of torque. They are typically used in pumps for seal-less applications; keeping corrosive, toxic, or flammable liquids from escaping into the atmosphere.
Non-Contact Magnetic
Sealed Power Transmission for Demanding Environments
Product Definition
Non-contact magnetic coupling is a torque-transfer device that uses permanent magnets or electromagnetic fields to transmit rotational motion without physical contact. It eliminates the need for mechanical seals, enabling leak-free and maintenance-free operation in critical applications.
How It Works
Dual Rotors: Consists of an inner rotor (driven by motor) and an *outer rotor* (connected to load), separated by an air gap or containment barrier.
Magnetic Interaction: Magnetic fields between rotors create synchronized rotation, transmitting torque across the gap (up to 500 Nm).
Containment: Hermetically isolates fluids, gases, or vacuum environments (e.g., pumps, reactors)
Key Advantages
Zero Leakage – Ideal for handling toxic, corrosive, or high-purity media (chemical, pharmaceutical).
Wear-Free Operation – No friction losses, extending service life by 5-10x vs. mechanical seals
Overload Protection – Slip at torque limits prevents equipment damage
Customizable – Adjustable air gap (1–50 mm), torque capacity, and materials (SS316, Hastelloy, PTFE).
Industry Applications
Chemical Processing: Seal-less pumps for acids, solvents.
Semiconductor Manufacturing: Vacuum chamber drives with zero particle generation.
Food & Beverage: Hygienic mixers avoiding lubrication contamination.
Renewable Energy: Corrosion-resistant wind turbine pitch control.
Why Choose Magnetic Couplings?
Reduce Downtime: Eliminate seal replacement costs.
Energy Savings: No friction = lower power consumption.
Compliance: Meet API 685, ISO 2858, and EHEDG standards.
