Double Balanced Cartridge Design
   Double balanced for high pressure pump applications.
   The cartridge design makes installation and handling
   much easier and allows sealing in a dry or lubricated
   medium.

Heat Shrunk Rotary Face
  Our patented face attachment design increases seal life.
  Uniformity of installed face in the holder reduces
  possibility of face separation, shattering, or cracking.

Conforms to API 610 and 682
   Made to North American ANSI Pump Sizes.
   Manufactured to the highest quality standards.
   Conforms to most North American Pump Designs.

Internal & External Pumping Ring
   The internal pumping ring design maximizes lubrication
   and seal face cooling, while the external pumping ring
   maximizes flow in convection applications as well as
   removing high consistency process away from the
   sealing faces.

Applications
   Convection pumping
   High Consistency Pumping when flush contamination is
   not desirable
