FEATURES:

  • Incorporated pumping ring improves the movement – and the cooling effect – of the barrier fluid during operation

  • Tandem design maintains product and barrier fluid on O.D. of both seals for increased safety and heat dissipation

  • A tangential connection maximizes the flow of barrier fluid

  • Can be operated in pressurized or non-pressurized state configurations

  • Springs are located out of the product

  • Double balanced inboard face allows for reverse pressures in upset conditions

  • Easy to install cartridge design

  • Fits ANSI standard and big bore pumps

  • Metric sizes are available
