Description

EMG1 Rubber Bellows Seal

The EMG1 is a cartridge-type mechanical seal that utilizes a flexible, rotationally-mounted rubber bellows as both the secondary sealing element and the spring mechanism. This innovative design eliminates traditional coil springs and shaft-mounted O-rings for enhanced reliability.

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 (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

Technical Evolution: Features 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
Application Versatility: Suitable for centrifugal pumps, screw pumps, submersible pumps, and can be configured as a tandem or back-to-back double seal for hazardous media or higher-pressure applications
Selection Imperative: Correct selection of face material combination and elastomer compound for the bellows must be based on exact fluid composition, temperature, pressure, pH, and solids content
