Mixer & Agitator Sealing Solutions
Industrial agitators, chemical mixers, and blenders feature long, cantilevered shafts operating under significant radial runout and variable batch viscosities. Specialized sealing systems are required to prevent product contamination and hazardous vapor emissions.
Key Engineering Considerations for Agitator Sealing
Mixer shaft dynamics present unique sealing challenges compared to conventional centrifugal pumps:
Shaft Deflection & Runout
Long hanging shafts experience lateral movement. Robust bearing support and cartridge seal designs are essential to absorb runout without face chipping.
Vessel Pressure & Vacuum
Reactors frequently cycle between deep vacuum and positive internal pressure during chemical synthesis batches.
Dry-Running Capability
Top-entry mixers often require dry-running barrier seals or specialized support systems to prevent contamination during batch fluid level fluctuations.
