ChemShear
ChemShear Impellers are made in 4 different styles. Style 1 has the widest blades and style 4 the narrowest blades. Various processes require different ratios of shear and pumping. The wider blades pump more, and the narrower blades have the higher level of shear. They work well in applications which require moderately high shear but also some level of pumping. Many high shear devices are very low in pumping capability and require an auxiliary impeller to provide turnover. ChemShear impellers often overcome the need for an auxiliary pumping impeller. ChemShear impellers have been used in microencapsulation processes producing particles in the 2 micron range.
