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.
