GENUINE FLOW-MECH ENGINEERING

Highly flexible elastomeric core designed to absorb axial shaft movement

Mechanical Seals

Rubber Bellow Seal

This type seal is generally used in sewage applications, waste water pumps, & fuel injection pumps.


Material Specifications

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

Core Structural Advantages

High Misalignment Tolerance

The flexible elastomeric rubber bellow naturally absorbs axial play, shaft run-out, and angular misalignment, ensuring the seal faces stay securely closed during operation.

Shaft Protection Core

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.

Non-Clogging Construction

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.

Target Applications

This specific Rubber Bellow architecture is heavily relied upon across utility and medium-duty fluid handling systems:

  • Municipal & Industrial Sewage Applications
  • Heavy-duty Waste Water Pumps
  • Compact Fuel Injection Pumps
  • Effluent treatment & fluid processing lines
  • Commercial domestic water pump systems

Handling Viscous Fluids or Clogging Media?

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.
