Advantages

  • Ideal for use in ANSI process pumps
  • Universal applicable for packings conversions, retrofits or original equipment
  • Seal for standardizations
  • No dimensional modification of the seal chamber necessary, small radial installation height
  • No damage of the shaft by dynamically loaded O-Ring
  • Extended service life
  • Installation faults are avoided, cost-effective
  • No damage caused by dirt entered during assembly
  • Straightforward and easy installation due to pre-assembled unit (reduced down-times)
