LUMPP COAXIAL OR COUNTER-ROTATING MIXER : Industrial mixing solution for complex rheology
The LUMPP counter-rotating coaxial agitator is a mixing system providing dual agitation to handle even the most viscous liquids. This high-performance industrial agitation equipment has an impeller positioned at the centre rotating in one direction, and a second impeller against the wall rotating in the opposite direction to the central impeller.
It offers an optimised homogenisation solution for mixing products with a high viscosity or complex rheology (non-Newtonian fluids).

ADVANTAGES OF THE LUMPP COAXIAL COUNTER-ROTATING MIXER
Unrivalled performance for complex processes
Conceived and designed specifically to handle extreme operating conditions such as very high pressures and temperatures, this counter-rotating mixer offers an optimum solution for mixing products with a high viscosity or complex rheology.
Thermal adaptability
The anchor and scrapers promote temperature homogenisation in processes involving heat exchange at the tank wall (double envelope).
Wide field of application
This industrial agitation system can be used for any type of mixing operation, offering a virtually limitless range of technical applications.
Simplified installation and maintenance
A dismantling system that does not require the tank to be emptied can be fitted on request for agitators with a mechanical sealing system.

Description of the LUMPP counter-rotating coaxial mixer
The LUMPP counter-rotating coaxial mixer features a central impeller to achieve rapid mixing by projecting the product towards the walls of the tank. Depending on requirements, these impellers can have a helical screw, dispersion turbines, inclined turbines or pump profile propellers to intensify their effect and facilitate heat exchange.
At the same time, the two- or three-armed anchor provides slow agitation in the opposite direction to the central agitation, counteracting the movement caused by the rapid mixing.
The combined action of these two coaxial impellers rotating in opposite directions ensures that even the most viscous fluids are set in motion and the entire volume is homogenised.
For the most viscous products, or mixtures with a tendency to clog, the anchor is fitted with scrapers to prevent the formation of a film on the walls.
The LUMPP coaxial mixers feature a variety of impellers selected by our experts to suit different industrial processes and applications. They can include anchors, ribbons, scrapers or features specific to polymerisation.

HASLER Group global support services for LUMPP mixing solutions
Our team of experts in LUMPP counter-rotating coaxial mixers offers:
/ Computer simulations using CFD (Computational Fluid Dynamics) to model the agitation of a product in a tank in three dimensions, simplifying the process of developing, optimising and validating agitation systems.
/ Rheology audits and tests to ensure optimum efficiency for your mixing equipment.
/ Services designed to upgrade/recondition equipment in order to:
-
- Make your processes more reliable: dealing with material fatigue (mechanical reinforcement, blades, shafts, etc.)
- Make your processes more efficient: optimise your mixing processes by adapting them to new constraints, improving yield, homogenisation, dilution, chemical reaction etc.
- Improve your anaerobic digestion processes mechanically: dealing with obsolete existing equipment when it breaks down (changing parts: shafts, impellers, seals, supports, junction flanges etc.)
- Provide advice on how to improve the environment: mixture properties (corrosive or abrasive products, etc.); atmosphere (saline, corrosive air, explosive atmosphere etc.)
/ On-site services covering assembly, commissioning of industrial agitation equipment and on-site or remote assistance, from maintenance to repair.
/ Supply of spare parts: agitator shafts, blades and propellers, mechanical seals, geared motors and torque limiters.
/ A wide range of training modules on the use, optimisation and maintenance of your industrial mixers.
