Mining Seals

Due to harsh conditions, mining requires very robust sealing solutions. Resistant to HFA, HFB, HFC fluids or mineral oils. Wipers and guides specially adapted to the sealing system complete the range.

Mining Seals

Mining seals are mostly very robust rod and piston seals made of NBR, HNBR, FKM with fabric reinforcement or PUR, resistant to flame-retardant hydraulic fluids such as HFA, HFB, HFC fluids, water or mineral oils. Wipers, guide elements and O-rings are also included. All components are characterised by their very good suitability in rough operating conditions.

Our customers benefit from our comprehensive technical know-how and many years of experience in sealing applications in this industry. The parts are used for hydraulic components in boring and shield support as well as for pumps and valves.
