V-AN pumps are used all over the world. The self-regulating centrifugal pumps master even the most difficult pumping tasks. What is new is the innovative sealing principle: Lip seals replace the conventional double mechanical seal. Dry running is possible for several hours. Certified by TÃœV, the V-AN with its innovative seal is "technically leakproof" under the statutory requirements of Germany's Technical Instructions on Air Quality Control (TA Luft).
