Advantages

The EA100 is the specialist for low duty applications and 

one of our historic and bestselling seals in this sector. The 

seal is easy to handle and quick to install. An incorporated 

garter spring assures a good grip of the bellows on the 

shaft and enhances satisfactory sealing performance. With 

the ability of the bellows to stretch and tighten, the EA100 

is insensitive to shaft movements. 

The seal design is available in 3 types, each with a 

different impeller connection: EA102 is with a collar. 

EA103 is without a collar. EA104 provides a different coil 

spring installation. More information on EA103 and EA104 

is available on request.
