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.
