Impellers and Shafts

Stirring objectives are highly specific to the application, of which the impeller is merely one part.  Adjustments to impeller placement in vessel, stirring speed, use of baffles, and the volume of materials mixed are all factors, which sometimes require empirical knowledge and/or trial and error to get the right combination for stirring success.  

Scott Process engineers have the product knowledge and experience to guide in product selection for a wide range of stirring applications, but the true test is done onsite.   Contact us to discuss your application and to schedule a demonstration.
