Anchor/Gate type impellers are close-clearance impeller. This impeller provides adequate mixing under the laminar flow conditions encountered viscosity applications for heat transfer. These are many applications that other type of impellers is integrated with the anchor.This impeller sweeps the whole wall surface of the vessel and agitates most of the fluid batch through physical contact. Anchor impellers are used for liquid viscosities between 5,000 and 50,000 cP. When reaction /mixing homogeneity is required, other type of impellers are recommended.
