High processing capacity

LUMPP XXL mixers are developed for large-scale production, enabling large volumes of liquids or materials to be processed while ensuring homogeneous mixtures in very large tanks.

High level of resistance to difficult conditions

Designed to operate under demanding conditions, LUMPP heavy-duty mixers are able to withstand high temperatures and pressures and corrosive environments. Featuring a speed reducer with a high service factor, this continuous industrial mixing solution guarantees robustness and efficiency.


The guide turret limits the transmission of load from the speed reducer, optimising its longevity.

HASLER Group global support services for LUMPP mixing solutions


Our team of experts in LUMPP heavy-duty industrial mixers offers:  

/ Computational Fluid Dynamics (CFD), a three-dimensional simulation of the agitation of a product in a tank. This method simplifies the process of developing, optimising and validating agitation systems in accordance with the specifications, based on the calculations involved and their interpretation. 

/ On-site services ranging from mixer installation to the commissioning of agitator equipment, maintenance and repair. 

/ Rheology audits and tests to ensure the optimum efficiency of your mixing systems. 

/ Supply of spare parts to guarantee the efficiency of your equipment: agitator shafts, blades and propellers, mechanical seals, geared motors and torque limiters. 

/ Services to modernise/recondition your equipment in order to: 

  • Make your agitation processes more reliable: dealing with material fatigue (mechanical reinforcement, blades, shafts, etc.).
  • Optimise your mixing processes: adapting to new constraints (improving yield, homogenisation, dilution, etc.).
  • Improve the mechanics of your process: avoid equipment breakages (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.).

/ A wide range of training modules to enable the optimum use of your industrial mixers.
