Our PROGRESSOR®-series stands for long durability. The best example is the PROGRESSOR® 2  with its new geometry. Its the advanced version of the classical 2L6 stator.

When we think of rubber in connection with automobiles we immediately think about its application as tires. However, beyond this component known to everybody numerous other rubber parts, rubber-metal and rubber-plastic connections are used in a variety of modules in an automobile. They make it possible that modern automobiles are able to set standards with regard to safety, efficiency, comfort, and reliability.

On the basis of these relevant characteristics of the flexible rubber material, pure rubber parts, such as rubber-metal and rubber-plastic elements are used in a number of applications.

For transformer weights from 0.5 t up to 2.5 t distributed among 4 bearing block parts. Without the use of elastic elements between the castors and the underground the vibrations which arise during the operation of a transformer are induced into the adjacent structures. This structure-borne sound is not only unpleasant but it also damages the structure. Vibrastop transformer bearings cannot avoid the vibration of the trafo but they substantially reduce the transfer to the surrounding. The decoupling effect is based on the greatest difference between the own frequency of the smoothly placed transformer and the excitation frequency which arises from the operation of the transformer.

For transformer weights from 2.5 t up to 12 t distributed among 4 bearing block parts. Without the use of elastic elements between the castors and the underground the vibrations which arise during the operation of a transformer are induced into the adjacent structures. This structure-borne sound is not only unpleasant but it also damages the structure. Vibrastop transformer bearings cannot avoid the vibration of the trafo but they substantially reduce the transfer to the surrounding. The decoupling effect is based on the greatest difference between the own frequency of the smoothly placed transformer and the excitation frequency which arises from the operation of the transformer.

For transformer weights from 12 t up to 25 t distributed among 4 bearing block parts. The stronger the deflection, the smaller the own frequency. However, in order to ensure a long life of the transformer a construction-related maximum of spring deflection should not be exceeded, for that reason a graded product range is available.

For transformer weights from 25 t up to 32 t distributed among 4 bearing block parts. The stronger the deflection, the smaller the own frequency. However, in order to ensure a long life of the transformer a construction-related maximum of spring deflection should not be exceeded, for that reason a graded product range is available.

Already in 1930 Professor René Moineau filed a patent application: the progressive cavity pump. Since then the pump technology has become indispensable.

In drilling technology the principle of progressive cavity pumps is used in the opposite way. Here the drilling material is transported through the stator and drives the drill head. The strain on the material is enormous: the most difficult conditions of use with partly high temperatures and aggressive material. The EVEN WALL® technology from Kächele offers great advantages in the drilling technology: with the same performance the shape permits a shorter construction form. More flexibility and small drilling radiuses are thus feasible.
