Choose the right stirring shaft for your application

Choose the right stirring shaft for your application
Overhead stirrers require stirring shaft for precise working. Choosing the correct stirring shaft is an important step to obtain the best stirring performance. 

It is important to evaluate the characteristics and the effects on the fluid of the stirring shaft, together with the volume and viscosity: 
  • Desired type of flow: Axial, Tangential, Radial; 
  • Speed range of your application 
Contact a VELP Specialist that will guide you to choose the correct shaft for your sample and application!
