DST Magnet Drive Couplings

DST is a specialist manufacturer of permanent magnet drive couplings for gear pumps, rotary piston, centrifugal and liquid ring pumps, as well as agitators, stirrers and mixers.

Benefits
DST hermetically sealed drives combine the advantages of a maintenance free, "failure-proof" sealing system with a torque transmission coupling that doesn't wear. If the maximum torque is exceeded, the coupling will break transmission, protecting it from overloading.

This Ensures:

• the safety of personnel and the environment when handling hazardous chemicals
• the integrity of sealing when compressing gasses or pumping vacuums,
• the risk of contamination is minimised in sensitive pharmaceutical, biological and food processes,
• and is ideal in fit-and-forget situations where the risk or cost of equipment leaking in service is unacceptable

Principle Applications

• Pump Manufacturers
  Manufacturers are increasingly out-sourcing mag drive production to DST due to their attractive pricing for standard items and special designs
• OEMs and end-users
  Mag drives for new projects
• Agitator, Mixer and Stirrer Manufacturers
  mag drives offer considerable advantages by providing gas tight hermetic seals for both top and bottom mounted stirrers and mixers therefore avoiding contamination
• Ceramic bearings
  DST provide complete ceramic bearing cartridges comprising radial and axial bearings used extensively in centrifugal pumps.
• Special coatings
  Chemical industries often pump highly aggressive or sensitive media. The wetted rotor in our mag drives can be encapsulated in stainless steel or hastelloy, or coated in PP, PFA or PVDF. Likewise canisters can be similarly coated or made from hastelloy, special plastics or ceramic.
• Seal cartridge replacement
  Most shaft seals and seal cartridges can be replaced with a mag drive eliminating seal wear and maintenance costs, seal failure and leakage and lost production time.
• Individual solutions
  DST uses CAD techniques to offer individual solutions for our customers. We can fabricate special components to your specifications at very competitive prices.
