Key Features
- inch dynamic elastomer backing layer engineered to support primary wetted diaphragms.
- Absorbs intense mechanical flexion stresses to significantly extend fluid-side component lifespans.
- Superior kinetic shape memory ensures the layer stays dimensionally stable over millions of cycles.
- Acts as a vital secondary boundary to protect the air motor section if a leak develops on the wet side.
- Sized to exact dimensional tolerances for a uniform, tightly balanced compression perimeter lock.
