The SMA model features a patented flow channel design. During cleaning, the flow channels force cleaning fluid through the bearing area, providing very effective and repeatable cleaning results. SMA generates very low shear forces, which makes it ideal for applications with shear sensitive products, such as mammalian cell cultures.
SMO is an open design that exposes all surfaces to the cleaning solution just by means of directing flow from a spray ball to the impeller head. It is not necessary to submerge it during cleaning.
