Impeller for shear-sensitive mixes
24 Feb 2005
The Sentinel impeller from Mixing Solutions has been recently developed to mix highly shear-sensitive materials.
Suitable for new installations or retrofitting to any existing mixer drive, the impeller features wide, large diameter blades that promote high flow and uniform distribution of shear.
Adaptable to vessels with limited flange size and manway access, and said to be particularly suitable for pharmaceutical and special batch mixing applications, the impellers are available in fully-welded or bolted designs, with different materials, coatings and surface finishes.
Ready to ship immediately for standard applications, and rapidly produced in non-standard designs, they can be readily adapted for any special mixing configuration to meet process requirements. They also operate with varying liquid levels.
The units were designed for low-shear applications where fluid motion is required to suspend solids, blend fluids or disperse gas without the risk of product damage from bubble breaking. With minimum horizontal hold-up surfaces and broad low-angle vertical projections, the impellers also suit cleaning-in-place systems.
The impeller design has already been proven in applications such as polymer production and processing, crystallisation, filter feed fermentation and biological growth processes.
