Description

Wave Spring Mechanical Seal is a high performance sealing solution that uses a wave spring to provide constant and uniform face loading.

The wave spring offers excellent resistance to clogging, reduced wear, and is more compact than conventional multi coil spring designs.

It is widely used in high speed pumps, high temperature services, and applications where space is limited and reliability is critical.
