High-performance disperser and deflaker discs with optional QST (Quartz Surface Treatment) for superior contaminant dispersion and stickies reduction.
Parason manufactures precision-engineered discs for all types of dispersers and deflakers. Available in full circle and segmental designs, these discs are built for high-temperature dispersion and deflaking applications with superior wear resistance and consistent performance.
Each disc is manufactured using special alloy casting and CNC machining to ensure uniform tooth geometry, precise gap control, and extended service life across all operating conditions.

Disperser discs often face initial issues like vibration, noise, load hunting, and unstable performance during the break-in period.
To overcome such problems Parason has developed advanced Quartz Surface Treatment (QST).
