The energy savings are the result of a newly developed filling geometry based on a labyrinth-like structure. The patent-pending application design reduces internal backflow and significantly lowers no load power.
PluraMaze is available in three variants for different requirements: PluraMaze 5.3 for customers with a primary focus on refining results and energy efficiency, PluraMaze 5.6 for a balanced combination of energy efficiency and lifetime, and PluraMaze 6.5 optimized for maximum lifetime. This modular approach allows paper manufacturers to select the ideal type depending on their operational priorities.

The new PluraMaze 5.6 variant optimized for European and Asian OCC pulps enables enhanced fiber treatment and delivers a longer lifetime. PluraMaze can deliver a 70 to 80 percent increase in lifetime compared to Pluralis, Voith’s previous filling generation under comparable operating conditions. This performance directly reduces annual wear-part costs and the frequency of filling changes.
