Anchor & Sweep

Model U044SW


Achieve enhanced process results with the addition of silicone sweep blades to our popular U044 anchor impeller. The impeller with sweep is effective for low speed, high viscosity mixing up to 38,000 mPas. The tangential flow 102 x 102 mm (4 x 4 in) anchor blade is welded to an 9.5 mm (⅜ in) diameter shaft, all electropolished 316L stainless steel. Sweep accessory blades slide over the anchor arms, enabling the combination to scrape sides of a standard 4 L beaker as it stirs. Sweep material silicone SCX 0570 is compliant with FDA 21 CFR 177.2600.  A vessel clamp is required when using this impeller. Due to the torque required for effective stirring, we recommend using only with the Caframo overhead stirrer models BDC1850 and BDC3030.
