Merkel Grafolan consists of graphite yarn which is created through an energy-intensive thermal transformation process. It features high chemical resistance and temperature stability. An added lubricant ensures good running-in behaviour at all speeds. Merkel Grafolan is used in many areas of chemistry-in pumps, agitators, and paddle dryers-as well as in feed water pumps for energy production. Compression-moulded rings from Merkel Grafolan 6576 (without additional lubricant) are supplied.
Production advantages
- High temperature resistant
- Also seals for slight shaft deflection
- Good heat dissipation.
