Highly flexible elastomeric core designed to absorb axial shaft movement
This type seal is generally used in sewage applications, waste water pumps, & fuel injection pumps.
| Seal Faces | Sic / Carbon Vs Ceramic / Sic |
|---|---|
| Secondary Seals | Viton / EPDM |
| Metal Parts MOC | SS-304, SS-316, SS-316L |
| Design Profile | Elastomeric Bellow / Single Coil Spring Protection |
The flexible elastomeric rubber bellow naturally absorbs axial play, shaft run-out, and angular misalignment, ensuring the seal faces stay securely closed during operation.
Because the elastomeric bellow tightens down securely onto the shaft without sliding dynamic parts, it completely eliminates shaft scoring and fretting wear underneath the seal area.
The open spring layout combined with a smooth rubber profile resists particle build-up, making it perfect for handling fluids with suspended solids or stringy particles.
This specific Rubber Bellow architecture is heavily relied upon across utility and medium-duty fluid handling systems:
Rubber bellows require proper elastomer pairing (Viton vs EPDM) depending on chemical exposure and fluid temperatures. Contact our technical team today to select the correct composition for your application.
