• Contamination can greatly increase wear – specifi cally from abrasive media from
the surrounding area, such as sand and silicates, e.g. from construction as well as
machining processes in the transfer system (e.g. welding beads, pumice powder,
glass shards, chips, waste parts, etc.). Maintenance intervals should be signifi cantly
shortened under these circumstances.
• Resistance to media and contamination does not mean that functional safety is
guaranteed in every case.
– Liquids that thicken as they evaporate and become highly viscous or adhesive
(sticky) can lead to malfunctions.
– If they get carried onto systems with rollers, media which have a lubricating effect
can lead to a reduction in the drive power that is transmitted via friction.
In such instances, special care must be taken when planning the system, and the
maintenance intervals must be correspondingly shortened.
