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.

Wiper 1A1

Wiper with flush housing end, snap fit. The wiper 1A1 is universally applicable and particularly suitable for applications in which a flush housing end is tobe achieved. Depending on profile width and diameter, snapfit in closed and undercut housings is possible. Other materials are available for very high or very low operating temperatures (see PDF Catalogue or contact our application engineers). Snap fit is dependent on the profile width and diameter in the case of the materials POM, PA and PE. Also available in special sizes at short notice from current production.
