Sintex a/s is a specialist in the production of permanent magnetic couplings in corrosion-resistant materials. We have always focused on providing maintenance-free solutions with unique advantages – both compared to mechanical solutions and other magnetic solutions.

Our couplings are used within, for example, the pump industry, the pharmaceutical industry, the chemical industry, the biotechnical industry and the food industry – usually with application in:

The magnets can be fully enclosed in stainless steel to protect them against all external factors, and the coupling can operate directly as a wet runner in liquids, if wanted.

It is possible to place a separation can between the two rotating drives to isolate two different medias, for instance, to keep liquid on one side and air on the other side. Sintex provides a unique can with a thickness equal to just four sheets of paper, thus allowing for a high energy efficiency while maintaining high strength.

Sintex magnetic couplings provide a wide range of advantages both compared to mechanical solutions as well as other magnetic solutions. Figure 2 summarizes the main advantages.

Permanent magnetic couplings have also been found to permit higher assembly tolerances compared to mechanical solutions.

Unlike traditional solutions, magnetic couplings can accommodate considerable differences in eccentricity between the shafts. This results in greater flexibility in the radial and axial alignment of the system, and the load reduction on the bearing system.

Sintex’ innovation department provides consultancy services in connection with product development. We are very interested in open cooperation to optimize the product, material know-how, processes and production, thus enabling our customers to lead the way within new technologies and manufacturing processes in their core business areas.
