Improving Balancing Processes
Posted by Angelica Pajkovic | 11 March 2019
The goal of balancing is to align mass center with geometric center. Unbalance occurs when the mass center axis is not aligned with the geometric axis.

The seal is the key: Prerequisites, requirements and intrinsically safe solutions
Posted by Deirdre Morgan | 11 July 2017
The functional principle of centrifugal pumps is based on hydraulics with an impeller and casing, as well as a seal and bearing unit. The task of the sealing system is to seal off the rotating shaft against the surrounding environment. Depending on the type of application, various sealing systems are in use for centrifugal pumps. The influence of the type of seal on the performance of the pump should not be underestimated.
