Mining Minerals & Materials

Safety is the highest priority when it comes to working underground. This puts the greatest possible quality demands on mining machinery, products and service providers. At the same time, operating efficiency plays a key role in this industry as well. So it is essential to bring three factors into harmony: cost minimization and the simultaneous maximization of productivity and safety.

Sand, mud, water and fallen rocks are just a few of the challenges facing seals in mining operations. In addition, there are peak pressures of up to 250 MPa, which require a special sealing element design. High extrusion resistance is especially in demand. Parts of the seal should not extrude into the clearance gap between the equiptment elements.

Extending the operations intervals between overhauls and repair downtimes is crucial, since overhauls and repair downtimes cost indirect loss of profit.
