Chemineer”s Clean Sweep impeller provides top-to-bottom motion with global movement at tank walls, even when center-mounted on a cylindrical vessel without the use of internal baffles. The blades are designed to produce thorough mixing throughout the entire vessel, yielding a homogenous mix and providing good off-bottom suspension of many materials. The impeller technology, containing two slightly downward-curved blades vertically mounted to the impeller hub, prevents buildup on horizontal surfaces, allowing components to be easily cleaned. The impeller is a good fit for low-shear, high-purity sanitary mixing applications and accommodates mixing at low liquid levels. All-welded, constructed, or removable designs are available.
