The CDSA™ cartridge double mechanical seal forms the basis of the engineered sealing system. The standard seal unit is 316 Stainless Steel with Carbon, Tungsten Carbide and Silicon Carbide faces, available with Viton®, Aflas®, EPR and Kalrez® elastomers. This fundamental design is changed through modular component options to suit the requirements of the specific application.




 1.   Self-aligning stationary seal-faces with radial contacting pin drive which minimizes damage in stop / start applications and viscous fluids

2.    Bi-metal CDSA™ option also includes Exotic Alloy wetted components at minimum price premium for use with corrosive chemicals


  3.  Hydraulically balanced seal-face technology for reduced power consumption


 4.   Non-shaft-fretting sleeve elastomer and positive set screw shaft drive


  5.  Independant seal face design to enhance safe containment of process fluid in the event of damage to any individual sealing element


 6.   Multiple spring seal face loading


 7.   Sizes available from 1.000" to 5.000" (24mm - 125mm) in standard and ANSI Plus gland formats larger sizes up to 12.000" (300mm) available on request
