Anchor impellers

Anchor Impellers



Low Clearance Impellers

  • The anchor impeller and the helical impeller are the two commonly used close clearance impellers.
  • The diameter of the close clearance impellers is typically 90 – 95 percent  of the inside diameter of the vessel.
  • The shear near the vessel wall reduces the build up of stagnant material and promotes treat transfer.
  • The anchor impeller is a radial flow impeller
  • Helical impeller provides axial discharge of material by producing strong top to bottom motion
  • Anchor blades may be used in combination with other types of impellers
