• Separation seal
Storage and Protection of Dry Gas Seals
• Dry storage place
• Prevention from radiation, heat, steam and ozone
• No use of corrosion protection agents
• Re-qualification of seal cartridge before installation
• Protection of spare gaskets from heat sources
Basic Installation Pre-Requisites
• Follow plant safety regulations
• Secure mixer or agitator shaft
• Remove coupling and/or drive
• Remove existing seal assembly
• Remove burrs and sharp edges
• Check shaft and vessel flange requirements
• Check assembly drawing
