A620

New LIGHTNIN Impeller for Transitional Flow Regime - Medium to High Viscosity Fluids

The LIGHTNIN A620 impeller has been designed and tested specifically for improved mixing performance in transitional flow regime blending applications. Certain applications, including smaller vessels and blending non-Newtonian materials, will benefit from the unique advantages of theA620 designs. Common examples include: personal care products, heat transfer applications, polymerizations and asphalt products.


	FEATURES of A620	BENEFITS of A620
	Low blade profile	Can pass into vessels with limited manway openings
	Low power number	Larger D/T with lower torque
	Large impeller diameter to tank diameter ratio	Lower power required for bulk motion, blending and heat transfer applications, especially in high viscosity and/or non-Newtonian fluids
	Reversible Design	Impeller can be run clockwise or counter clockwise for process flexibility
	Separation of inner and outer blades	Lower turbulence, smooth transition, more flow, less power
	More efficient transitional operation	Less power required than open impellers for bulk motion, lower cost than close clearance impellers (anchors/spirals)

Axial flow pattern Better process uniformity in the vessel from top to bottom
