- Avanceret cykelstidesign
It adopts advanced cyclical model of high pressure entrance and high pressure exit circulation ( see the arrow’s trance in section drawing). More suitable for vaporized mediums.

- Særlig selvbalancerende ydeevne af aksial kraft
There will be one stationary balancing plate between impeller hub and support disc if the diameter of impeller equals to or is larger than 250mm, this new design can make the axial force autobalance by adjusting the radial and axial gaps.

-Perfekt fleksibel forbindelsesstruktur
It adopts inserted structure for siliding bearing and thrust button. The tolerance rings are used for radial connection. Also tolerance rings are filled between in shaft and shaft sleeve to mitigate the pressure which shaft imposes on the shaft sleeve becuse of heat expansion.

-Containment shell
The stamped arc bottom of the containment shell improves the rigidity of the containment shell, and alleviates the stress concentration on the bottom of containment shell and then protects it from being damaged.
