2850 Double Seals designed for VOITH MS series pressure screen

TECHNICAL FEATURES

•Double-balanced, which makes the construction fully independent of pressure changes in both process and barrier fluid.

•Design is unaffected by pressure changes.Two sets of multi spring structures on the inner and outer sides of the double seal provide more stable spring loads for the two pairs of friction pairs, without affecting each other.

•It's designed for minimum damage risk — the rugged construction for all applications prevents failure and provides long and trouble-free service.

•Larger buffer chamber flushing space, bidirectional flow design, more significant cooling effect.

•Easy installation and low maintenance costs. Ultimate reliability for screen sealing requirements.

•It is recommended to use GLD (plan 54) for seal water control.
