Features and Benefits
• Rugged construction throughout makes BRC seals the toughest and most reliable metal bellows mechanical seals for difficult refinery pump services.
• Bellows diaphragm thicknesses start at 0.010 in. (0.25 mm)on small sizes and extend to 0.012 in. (0.30 mm) for the industry’s strongest bellows, capable of long-term chemicalexposure and low-stress performance.
• Alloy 718 bellows and end adapters satisfy NACE MR0103 and have the highest resistance to stress-cracking corrosion in sulfuric-laced environments at high temperature.
• Mounted in a flexible graphite ring to avoid shrink-fit distortions, the silicon carbide rotating face sustains a stable, flat sealing surface for reliable, low-leakage performance.
• Seal face combinations of carbon against silicon carbide or carbide against carbide are matched with the service conditions from heavy hydrocarbons to light products including some solids.
• Configurable with rotating or stationary bellows, BRC seals include a steam purge baffle under the stationary components to eliminate coking and prolong clean operation.
