Headquarters: Putnam, Connecticut, USA
Established: 1984
Main Products: Co-Axial Magnetic Couplings, Disc Magnetic Couplings, Custom High-Temperature Magnetic Couplings, Magnetic Drive Pump and Mixer Couplings
Company Overview: Magnetic Technologies Ltd. is a U.S.-based designer and manufacturer of magnetic brakes, clutches, and couplings, with its magnetic coupling technology specifically developed for non-contact torque transmission in magnetic drive pumps and mixers. The company's coupling designs can transmit torque through air or a non-magnetic containment barrier, allowing the driven side to remain isolated from the motor side and helping eliminate rotating seals in applications involving corrosive, toxic, or flammable liquids. Its co-axial coupling design provides a self-centering configuration with very low axial force, while its disc coupling design offers adjustable air gaps and is available for applications requiring different torque characteristics. Magnetic Technologies also states that its couplings can accommodate angular and parallel misalignment, operate at temperatures up to 140°C in standard designs, and can be customized for higher-temperature applications. For U.S. chemical-processing and industrial equipment buyers, this combination of domestic manufacturing, custom design capability, and application-specific magnetic torque transmission makes the company relevant when a magnetic coupling must be designed around the actual pump, mixer, containment barrier, and process environment rather than selected only by shaft size.
Company Advantages: Its U.S. design and manufacturing capability can simplify technical communication for American OEMs that need a custom magnetic coupling or application-specific engineering support. The company's focus on non-contact torque transmission is particularly relevant to buyers trying to reduce rotating-seal problems and maintenance in chemical and process equipment.
Suitable Customers: Chemical processing companies, pump OEMs, mixer manufacturers, process-equipment manufacturers, industrial machinery companies, and engineering teams requiring custom magnetic coupling solutions.
Headquarters: Kent, Washington, USA
Main Products: Inline SmartCOUPLING, Belt-Pulley SmartCOUPLING, Inline Adjustable Speed Drive, Belt-Pulley Adjustable Speed Drive
Company Overview: Flux Drive takes a different approach to magnetic coupling technology by concentrating on soft-torque transmission, cushioned starting, vibration reduction, energy savings, and adjustable-speed operation for rotating equipment. Its SmartCOUPLING products transfer torque across an air gap using magnetic induction and are offered in both inline and belt-pulley configurations, while its Adjustable Speed Drive product line is designed for applications requiring variable process speed. Flux Drive states that its technology can be used with pumps, fans, blowers, conveyors, compressors, and other rotating equipment, and its magnetic separation means the motor and load are torsionally disconnected without a physical connection between the two sides. This makes Flux Drive particularly interesting to U.S. industrial operators who are not primarily looking for a sealless pump coupling but instead need to address startup loads, vibration, motor loading, energy consumption, misalignment, or speed-control problems. Its products are also positioned for environments where poor power quality, lightning, moisture, or corrosive conditions can create problems for electronic variable-frequency drives.
Company Advantages: Flux Drive gives U.S. industrial users an alternative to conventional flexible couplings and certain electronic speed-control approaches when soft-start, vibration isolation, and energy reduction are priorities. Its inline and belt-pulley configurations also make it easier to consider magnetic torque transmission when replacing an existing rotating-equipment drive arrangement.
Suitable Customers: Wastewater plants, pump operators, industrial manufacturers, mining operations, marine facilities, manufacturing plants, fan and blower operators, conveyor operators, and companies managing high-inertia rotating equipment.
Headquarters: Morgan Hill, California, USA

Suitable Customers: Industrial OEMs, motion-control companies, medical equipment manufacturers, aerospace companies, motor manufacturers, pump manufacturers, engineering firms, and customers requiring custom magnetic assemblies.
A magnetic coupling transfers torque across a magnetic field without requiring the motor shaft to pass directly through the containment barrier. This makes it possible to isolate the process fluid from the drive side and eliminate the rotating mechanical seal as a primary leakage path. Magnetic Technologies specifically describes its couplings for magnetic-drive pumps and mixers handling corrosive, toxic, or flammable liquids, while FZMAG identifies chemical, oil and gas, refining, and pharmaceutical applications for its magnetic coupling products.
Non-contact transmission does not mean that alignment can be ignored. Excessive radial or angular displacement can reduce the effective magnetic gap, cause components to contact, change transmitted torque, or increase mechanical loading elsewhere in the equipment. Magnetic Technologies specifically publishes angular and parallel misalignment information for its coupling designs, while Flux Drive emphasizes misalignment correction as one of the benefits of its air-gap technology. U.S. buyers should therefore ask the manufacturer for the allowable angular, radial, and axial limits for the exact coupling configuration rather than assuming that all magnetic couplings tolerate the same amount of misalignment.
Many permanent-magnet magnetic couplings have a maximum transmissible torque. If the required torque exceeds that level, the magnetic connection can decouple or slip depending on the design. This is why selecting a coupling only according to the motor's horsepower can be risky. The manufacturer should evaluate continuous torque, startup torque, transient loads, possible pump seizure, viscosity changes, and other abnormal conditions before final sizing. For industrial applications, request both the rated operating torque and the overload or slip characteristics.
They can be particularly useful when a rotating or linear motion needs to pass through a vacuum boundary without using a conventional mechanical shaft penetration. QT Magnetic Solutions specifically identifies magnetic torque coupling and motion in vacuum as an engineering solution and provides material selection, mechanical design, FEA, fabrication, and assembly services. For semiconductor applications, buyers should additionally discuss cleanliness, outgassing, materials, particle generation, vacuum level, temperature, and the required testing or documentation before selecting a coupling.
Yes, custom development can be appropriate when the existing shaft geometry, installation envelope, torque requirement, or containment arrangement does not match a standard coupling. FZMAG, for example, provides custom inner and outer rotor engineering and states that its assemblies can be developed around customer drawings and application requirements. Magnetic Technologies also explicitly offers custom magnetic coupling designs. For a replacement project, provide the original coupling drawing, shaft dimensions, torque requirement, RPM, material information, and photographs if available.
