EA100

Versatile Mechanical Seal

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: o 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.
