Description

Technetics Group Brush Seals – Designed to increase airflow efficiency in engines and compressors Replacing labyrinth seals with brush seals from Technetics Group can reduce leakage by 5 to 17 times, thus providing significant turbomachinery efficiency and output gains. Brush seals work by absorbing the radial deflections between the shaft and rotor during transient operation. The seal then follows the rotor back to the steady-state operating position to maintain minimum leakage. The brush pack is composed of thousands of finely packed 2.8 to 5.6 mil diameter wire bristles. The bristle material, a cobalt or nickel alloy, is selected to provide an optimal combination of wear properties and oxidation resistance. The backplates and side plates are typically fabricated from stainless steel or nickel alloys. The primary consideration is the thermal expansion and contraction of the case material. Brush seals can be delivered as a single unit or in multiple segments. The bristles can be configured radially inward, radially outward or axially. FEATURES & BENEFITS Benefits: Reduced wear rate means longer life Consistent flow provides predictable performance Higher-pressure operation yields flexibility in design Reduced heat generation ensures a cooler rotor PRODUCT APPLICATIONS Aerospace Industry Industrial Turbines Marine Engines
