The Low viscosity and flow-controlled applications provides a combination of performance characteristics and high flow efficiency not available from other types of axial flow impellers

The Low viscosity and flow-controlled applications can produce the same flow and process results at a lower power than other axial flow impellers thus reducing operating and capital costs.

The Gas/ liquid applications with uppumping characteristics with up-pumping axial flow is the most recent development for gas/liquid applications. The Gas/ liquid applications with uppumping characteristics can be used for coalescing and non-coalescing systems and allows better.

• Mass Transfer
• Heat Transfer
• Shorter Mixing Times

Designed specifically for dependable draft tube service, theDraft-tube circulators. has a true airfoil shape and provides high flow, even in unstable process conditions, whilst minimising power requirements. A specific family of impellers (unique to Lightnin) based upon theDraft-tube circulators.design is available for use in draft tubes. Processes include alumina, gold, uranium and potash.

The traditional impeller for larger volume applications. Largely superceded by the Low/medium viscosity, flowcontrolled applications, it still has a specific role in applications where a degree of fluid shear is beneficial to the overall process result.

The Axial flow impeller for gas/ liquid applications is capable of dispersing gas and controlling flow patterns at significantly higher gas rates than other axial flow impellers. Compared to conventional Rushton type radial flow turbines, the Axial flow impeller for gas/ liquid applications can provide up to 30% greater mass transfer at equal torque and power consumption. Good axial flow patterns from the Axial flow impeller for gas/ liquid applications give good solids suspension and significantly reduce power requirements.

The Axial flow impeller for side entry applications is designed for the arduous requirements of pulp and paper applications. It is also used in other side entry applications such as oil storage and FGD (Flue Gas Desulphurisation). It is an axial flow impeller with a minimal radial flow component, unlike other conventional side entry mixer impellers.

The High flow impeller for higher viscosity applications. is designed to operate in higher viscosity fluids. The effectiveness of many high efficiency impeller systems which are designed to operate in the turbulent flow regime is impaired as the viscosity of the fluid increases and the Reynolds Number decreases. This is not the case with the High flow impeller for higher viscosity applications. The unique design of the impeller reduces both capital and operating costs. Blend times are also reduced compared to other open impellers used at low Reynolds numbers.

The High shear mixing and gasliquid Applications rushton turbine is the traditional impeller for gas - liquid mass transfer controlled systems. It is also used where higher shear is needed. The High shear mixing and gasliquid applications shown above has similar characteristics to the High shear mixing and gasliquid applications but gives:

• A higher power input in the gassed condition (reduced K factor effect)
• Lower power in the ungassed condition

The High shear, typically used for difficult to disperse pigments provides high shear rates. It is generally used in conjunction with a high flow impeller in applications involving a combination of blending and a need for physical change created by fluid shear
