Product Description
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.
•It's designed for minimum damage risk — the rugged construction for all applications prevents failure and provides long and trouble-free service.
•Double seal with multi spring structure, Sliding O-ring design has a large axial displacement.
•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.
APPLICABLE CHAMBERS TYPE
