Propeller

These are most common mixed flow (axial & radial) impeller. It is recommended for mixing of two or more low viscous liquid together. It provides effective liquid mixing solution. Mostly available in three blade version. Due to low manufacturing cost of this impeller it gives best economical solution to customer with less manufacturing time.

Hydrofoil

These are most efficient axial flow impeller. It is recommended for blending, solid suspension, heat transfer etc. It provides maximum flow at minimum power. Mostly available in three blade version. But different number & width of blade are also common in special applications. This is also called as fabricated propeller.

Pitch blade Turbine

These are axial flow impellers with a considerable amount of radial flow. It produces suction when placed near the liquid surface. Hence used for blending of immiscible liquids, solid incorporation etc. It is also a preferred choice for applications where the viscosity change during the process is large. These are mostly available in four blade @ 45 degree. But different no of blade with various angles are also used depending on application.

Counter Flow

Flow generated by impellers tip is opposite to the bulk flow produced by the central part. In many case where the slurry fluidity reduces due to high solid concentration. Tip of the impeller provides momentum to the fluid near vessel wall. These are mainly used for slurry with high solid concentration. It efficiently operates at much higher impeller to tank diameter ratio and have higher flow capacity than conventional impellers.

In many application, flow regime is not same throughout the process. It changes from turbulent to transition and even laminar flow in many application. This is most efficient impeller system in such application. It has capability to mix Newtonian as well as Non-Newtonian fluids.

Smith Turbine Impeller

Mostly used for gas dispersion application. Curve blade (Concave, parabolic etc.) disc can handle 2 to 6 times more gas than flat blade disk turbine. Power drop between gassed and un-gassed condition is very less than conventional flat blade disk impellers. Hence it is preferred choice for gas dispersion applications viz. Fermentation, Hydrogenation, Oxidation, Carbonization, Ethylation etc.

Single/Double Helical Ribbon Agitators

Helical ribbon impellers are designed especially axial and overall movement of the liquids. Such an impeller can be designed with an additional inner helix or auger used to pumping in the opposite direction. This is needed for the mixing of high viscosity materials. These impellers can also have one or two start helix. The quality of the final mixed product in these applications are very critical. Wall scrapers can be mounted on the impeller blades to improve heat transfer and homogeneity in sticky products.

Shear blade Impeller

Disperser disk provides large amount of shear and mostly used for liquid-liquid dispersion, powder dissolution or de-agglomeration etc. Commonly in this type of impeller application shaft is directly coupled with Motor to achieving the high RPM to generate effective shear between liquid.

Ruston Blade Impeller

The Rushton turbine is mainly used because of its extensive centrifugal effect for the dispersion of gas/liquid. This dispersion fosters the gas/liquid exchange for processes such as aerobic fermentation. It can also be found in special applications such as stripping type processes.

Anchor Type Impeller

Anchors/Gate type impellers are close-clearance impellers that fit the contour of the vessel. These impeller provide adequate mixing under the laminar flow conditions encountered in high viscosity applications for heat transfer. There are many applications that other type of impellers are integrated with the anchor. These impellers sweep the whole wall surface of the vessel and agitate most of the fluid batch through physical contact. Anchor impellers are used for liquid viscosities between 5,000 and 50,000 cP. When reaction/mixing homogeneity is required, other type of impellers are recommended.

Customized Impeller

We are also Provide Customized impeller design which depends on process requirement. We Dosimix Technologies consistently works on research & development of the Agitator Impeller design using Practical exercises, Computerized Flow simulation & analysis software to improve the blade efficiency for improvement of mixing efficiency with least cost & time.
