ZAVA® Seal-Ring was invented in 1986 by Frans Sramek. The Östrand mill of SCA Pulp was looking for a solution to the typical sealing problems.
”At Last” was the reaction of those who have been plagued by the constant need to change rubber seals on VFA and CCA filters at Pulp plants the word over.
The four hours of unpleasant work was cut to a few minutes. ZAVA® Seal-Rings have been used by Scandinavian Industry since 1986 and now they are used worldwide.
The inventor Frans Sramek is still working with the ZAVA® Seal-Rings together with members of his family. Zuzana, his daughter is the CEO of the company.
