Revolutionizing Bulk Powder Handling: How SEPCO’s Solutions Raise Industry Standards

By: SEPCO

Sealing systems for handling powders and bulk solids pose unique challenges, largely due to the abrasive nature and physical characteristics of these materials. Coupled with the fact that mechanical seals and packing require a barrier fluid or flush water, respectively, to reach optimal performance, an even greater challenge is presented. Barrier fluid and flush water are both incompatible with sealing dry powders. Using air as a sealing method overcomes these challenges. Here’s how SEPCO, with its innovative air seal technology (SEPCO SAS), tackles the difficulties in bulk material handling:

Difficulties of Sealing Powder and Bulk Solids

  1. Abrasive Nature: Many bulk materials are highly abrasive, causing rapid wear and tear on traditional mechanical seals.
  2. Particle Ingress: Fine and coarse particles can enter seal mechanisms, damaging seal faces and other internal components, which leads to leaks and operational failures.
  3. Material Build-up: Powders and bulk materials can accumulate around seal areas, leading to clogging and impaired seal functionality.
  4. Temperature and Chemical Exposure: High temperatures and exposure to chemicals can degrade seal materials unless they are specifically designed to withstand such conditions.
  5. Maintenance and Downtime: Traditional seals often require frequent maintenance and replacement due to the harsh operational conditions, leading to increased downtime and higher operational costs.

SEPCO’s Benefits and Solutions

SEPCO SAS Air Seals: These are non-contact seals that use a thin film of air to build a back pressure andcreate an effective seal, preventing direct contact between the seal components and the abrasive material. Here’s how they help:

  • Non-Abrasive Contact: By creating a barrier of air, the EXP air seals prevent abrasive materials from making direct contact with the seal faces, significantly reducing wear and tear.
  • Prevention of Particle Ingress: The air barrier effectively prevents particles from entering critical mechanical components, safeguarding against damage and extending the lifespan of machinery.
  • Handling Temperature Fluctuations: Air seals can operate effectively across a range of temperatures without the risk of thermal degradation that can affect traditional seals.
  • Reduced Maintenance Needs: Since there is no direct contact or wear, air seals typically require less maintenance, which reduces downtime and operational costs.
  • Versatility: SEPCO’s air seals can be used in a variety of applications, handling different particle sizes and material types effectively. These applications include, but are not limited to, mixers, blenders, agitators, screw conveyors, hoppers, and rotary air locks.
  • Increased Bearing Life: Powders have a tendency to migrate once they’ve leaked from the vessel. This can lead to ingress into bearings of the vessel itself or adjacent equipment, causing premature bearing failure.
  • Product Loss and Housekeeping: Effectively sealing equipment with air seals will drastically reduce product loss and housekeeping.

Additional SEPCO Services and Products:

  • Customized Seal Materials: SEPCO offers seals made from materials engineered to resist abrasion and chemical attack, suitable for the specific needs of powder and bulk solids handling.
  • Comprehensive Seal Support Systems: Includes auxiliary systems like purge and barrier fluids to manage and mitigate the challenges posed by particulate materials.
  • Training and Technical Support: SEPCO provides training for facility personnel on the correct installation and maintenance of seals, as well as ongoing technical support to ensure optimal seal performance.
  • Innovative Design Solutions: Besides air seals, SEPCO offers a range of sealing solutions that can be custom-engineered to meet specific operational requirements, ensuring higher efficiency and reliability.

By utilizing the non-contact technology of air seals and other specialized sealing solutions, SEPCO effectively addresses the unique challenges posed by the handling of powders and bulk solids. This approach not only enhances operational efficiency but also increases overall plant reliability and safety.
