Microtact designs, sells, manufactures, and services a complete line of impellers for high speed pumps, compressors, high shear mixers, static mixers, and heat exchangers. If there were only one conveying or mixing job to do, only one impeller would be required. However, there is a very wide range of problems in conveying and agitation, and the best impeller for one application may not be the best impeller for another.
