Helical Ribbon impellers are designed especially for axial movement of the liquid.
While the basic construction is with single helical ribbon, these Helical Ribbon impellers are usually designed with an additional inner helix used to pump in the opposite direction, which is very helpful for the mixing of high viscosity materials. Wall scrapers can be mounted on the impeller blades to improve heat transfer and homogeneity in sticky products.
Helical Ribbon impellers are suitable for very high viscosity up to 25,000,000 cPs.
For high viscosity mixing applications, Helical Ribbon impellers are commonly applied such as in the production of paints, polymer, creams, lotions, and pastes.
