Product Overview:
Our Double Mechanical Seals provide an extra layer of protection for your most demanding pumping applications. By using two sets of sealing faces (inner and outer), these seals ensure that hazardous, toxic, or expensive fluids never escape into the atmosphere. They are the gold standard for safety and environmental compliance in high-risk industrial processes.
Key Features & Benefits:Enhanced Safety: If the primary seal fails, the secondary seal takes over, preventing catastrophic leaks and environmental contamination.
Buffer/Barrier Fluid System: Designed to work with a seal support system (API Plan 52 or 53) that cools and lubricates the faces, significantly extending seal life.
Handles Aggressive Media: Ideal for fluids that are toxic, abrasive, explosive, or prone to polymerization.
Vacuum Protection: Capable of maintaining a seal even under vacuum conditions where single seals often fail.
Available in Cartridge Design: We offer "Double Cartridge" versions for easy installation and perfect face alignment every time.
