WMG1 Elastomer bellow mechanical seal replaced MG1
WMG1 is the most common rubber bellows mechanical seals allow for fast and easy installation. it is also be used as multiple seal in tandem mechanical seals in two sets arrangement. Mechanical Seal WMG1 is widely used in Chemical standard pumps, screw pumps, slurry pumps and Petroleum chemical industry.
Protection of seal face during installation due to special bellows design
Insensitive to shaft deflections due to large axial movement ability
Universal application opportunities
Important material certifications available
High flexibility due to wide offer on materials
Suitable for low-end sterile applications
Special design for hot water pumps (RMG12) available
Dimension adaptions and additional seats available
