Carbon Footprint vs. Handprint of Dynamic Sealing Systems

Abstract

In the future, sustainability and CO2 neutrality requirements will come from both customers and regulatory compliance. Each company should provide the greatest possible transparency regarding its sustainability efforts. In addition to the Footprint, the Handprint has to be considered, which can have a significant positive impact on sustainability during the product’s life span, including its development and production processes. In the case of dynamic seals, the reduction of friction, i.e., the optimization of the tribological system, makes a significant contribution to the Handprint. Based on this insight, a pressure rotary shaft seal has been developed with a specific sealing edge profile that reduces friction and wear, and thus increasing energy efficiency and service life.
