Johan Fondelius Flygt

CHALLENGE :: In the pumping world, engineers have long accepted the fact that any time there is a dynamic seal — a seal between two moving parts — there will also be leakage. But Johan Fondelius was determined to prove this rule wrong.

SOLUTION :: In 2003, using a patented sealing system that directs the leakage upstream away from the dry side of the seal to the wet side, Johan designed a “zero-leakage pump seal.” The seal itself acts as a micropump capable of reversing the flow of leaking liquid. Our pumps are living longer thanks to Johan’s refusal to accept leaks as an unalterable fact of life.
