Anchor Mixers feature a mixing impeller that follows the counters of the mixing tank to sweep the tank walls and direct it to the centre of the tank. On it's own an anchor mixers will provide gentle mixing in high viscisoity applications. However typically the Anchor mixer would be combined with another mixer either on the same axis or offset to provide complete agitation of the fluid in the vessel.
Anchor mixers are suitable for fluid viscositys from 5000cps to 100,000cps
