  • California Residents: PROPOSITION 65 WARNING
  • ID to OD pumping spiral groove arrangement places process fluid at the OD of the inboard seal.
  • Eliminates low flow regions in close proximity to inboard seal
  • Reduces dewatering and hang-up
  • Rotating mating ring imparts centrifugal flow to fluid in the seal chamber, which keeps fluid moving and helps prevent solids from falling out of solution.
