Description

EMG1 Rubber Bellows Seal


In essence, it is a cartridge-type mechanical seal that utilizes a flexible, rotationally-mounted rubber bellows as both the secondary sealing element and the spring mechanism, eliminating traditional coil springs and shaft-mounted O-rings.


Aspect Description
Core Design Rotating elastomer bellows design; optimized geometry for improved self-alignment and reduced stick-slip; full-length shaft protection sleeve.
Primary Advantages Full interchangeability with MG1 series; tolerant of shaft deflection; protected sealing faces during installation; robust performance in demanding services.
Typical Face Materials Antimony/Resin-Impregnated Carbon, Silicon Carbide (eSiC-Q7), Tungsten Carbide.
Bellows/Elastomer Materials NBR (Nitrile), EPDM, FKM (FPM/Viton®). Material selection is critical for fluid compatibility.
Metal Parts Stainless Steel (e.g., AISI 304, 316), Hastelloy.
Recommended Applications Industries: Chemical, Petrochemical, Pharmaceutical, Sugar, Pulp & Paper, Water & Wastewater, Food & Beverage.
Media: Water, wastewater, slurries (solids ≤ 5%), chemicals, oils, emulsions.

Key Technical Details & Recommendations

  1. Technical Evolution: The eMG1 features an optimized bellows geometry for better shaft follow-up and a proprietary PEEK-PTFE disc on the bellows foot, which acts as a self-cleaning and centering device against the shaft, enhancing reliability.

  2. Application Versatility: Beyond standard centrifugal pumps, it is suitable for screw pumps, submersible pumps, and can be configured as a tandem or back-to-back double seal for hazardous media or higher-pressure applications.

  3. Selection Imperative: Correct selection is paramount. The choice of face material combination and, crucially, the elastomer compound for the bellows must be made based on the exact fluid composition, temperature, pressure, pH, and solids content. Always consult the manufacturer's chemical resistance and temperature rating charts.
