Black Manual Round Rubber DMG1 Mechanical Seal, For Industrial, Packaging Type : Packet

Advantages

• 100 % compatible with MG1
• Small outer diameter of bellows support (dbmin) enables direct retaining ring support, or smaller spacer rings
• Optimal alignment characteristic through self-cleaning of disk/shaft
• Improved centering across entire pressure operating range
• No torsion on bellows
• Shaft protection over entire seal length
• Protection of seal face during installation due to special bellows design
• Insensitive to shaft deflections due to large axial movement ability
• Suitable for low-end sterile applications
• Dimension adaptions and additional seats available
