Where reliability, efficiency and long service life matter, magnets do the heavy lifting. We engineer magnetic couplings for sealless pumps and magnetic separation assemblies for process lines — in NdFeB and SmCo built for chemical, food and industrial duty, from prototype to production.
Two application families dominate the inquiries we receive — and both are decided by the magnetic components inside.
Mechanical seals are the number-one failure point in pumps. In chemical, pharmaceutical and food service, a leaking seal means contamination, downtime and safety exposure. A magnetic drive eliminates the seal entirely — but only if the coupling holds its torque for years.
Hot media and aggressive chemicals push standard NdFeB past its limits: irreversible flux loss, coating breakdown, coupling slip. Grade and protection chosen without real margin fail silently in the field.
Tramp metal in food powders, recycling lines and mineral processing damages equipment and fails audits. Separation performance depends on magnet grade, circuit design and how the assembly is built — not just magnet size.
Every unplanned stop costs more than the component that caused it. Industrial buyers need batch-consistent magnets and documented quality — so the coupling or separator validated at commissioning performs the same at year five.
Application-first engineering — we start from your media, temperature and torque, not our catalog.
Send us your pump speed, torque and slip tolerance — we review magnet layout, pole count and air gap on the inner and outer rotor, and recommend a coupling geometry that holds rated torque with margin at your maximum temperature.
NdFeB in high-temperature grades (SH/UH/EH) for standard duty; SmCo 2:17 where heat and corrosion rule out NdFeB. Encapsulation and coating options matched to your media — acids, solvents, CIP cleaning or outdoor exposure.
Ferrite and high-intensity NdFeB assemblies for plates, grates, drums and overband separators — configured to your material flow, particle size and throughput, from mining and recycling to food-grade powder lines.
Flux and dimensional inspection on every production batch, with reports your quality team can archive. What passed your commissioning test is what arrives in every replacement order.
Everything below can be customized to your drawings and specifications.
