English term or phrase: “actively lift” the faces of wet seals
Applying Spiral Groove Technology to Pumps
By the 1980s, John Crane engineers started working with these faces on mechanical seals for pumps, applying that same game-changing innovation to **“actively lift” the faces of wet seals**.
The results were impressive, and the potential for improving pump performance in key process industries was promising.
John Crane engineers kept working and launched the T8000 Dynamic Lift Up-stream Pumping seal in 1989.
Now—almost three decades later—John Crane remains the only seal company to offer this innovation for pumps.
Three Decades Prove Value
Today, John Crane customers who have applied Dynamic Lift Up-stream Pumping face technology have experienced seal life improvements from just two to three months up to five years in some instances.
Plus, with the right seal support system and piping plan, reliability issues due to poor water quality are virtually eliminated.
With hundreds of installations in the last few decades, John Crane is the best—and only—expert in applying the concept of active lift to mechanical seals for pumps.
How Does it Work?
Mechanical seals require a narrow gap between faces to allow a lubricating film to work; the gap must also be optimized to eliminate leakage.
The lubricating film thickness is measured in microns.
Debris in process fluids can create deposits, damage faces and cause hang-up.
Ultimately, seal life is shortened, and the MTBR of the pump is not acceptable.
The basic concept of John Crane’s solution is that the conventional seal is replaced by a low-volume, high-pressure “pump”—the Dynamic Lift Up-stream Pumping seal.

"активно промывать" пару трения в работающем в жидкости уплотнении
Explanation:
Конечно, никакого подъема колец в их конструкции нет, просто между кольцами пары трения поднимается (изнутри наружу) буферная жидкость. Можно перевести lift как "промывать" (как я предложил), а можно "поднимать/подавать буферную жидкость" (в паре трения)
