AIM AND APPLICATION FIELD

The following table lists the more common fluids (media) and suitable seal materials respectively. In selecting the seal the operating limits and constructional information for the relevant design should be taken into account. For technical or other economic reasons, other type of mechanical seals with different materials from the ones indicated in these tables, can be supplied (contact BT-Burgmann S.p.A.).

2.

TABLE OF MATERIALS

The simbology of the seal materials used in these tables follows the European Norm EN 12756:2000.
