Indirect-driven dynamic mixers

The indirect-driven mixer is equipped with an electric motor-driven gearbox.

Verdermix VFG - VKG - VWM Series

Shaft speeds between 15 and 300 rpm 

These types of mixers are an excellent choice when mixable products require blending with great care and intensity. A perfect combination of shaft speed and mixing blade size is of the utmost importance in processes of this nature. 

Options: bearing lantern, sealing lantern with a mechanical seal, lip seal or stuffing box, chemical resistant coating. 

Gearboxes options: Parallel shaft gearbox (VFG), Helical bevel gearbox (VKG), worm gearbox (VWM)

Verdermix VPM Series

Shaft speeds between 250 and 750 rpm 

This type of mixer is driven through a helical gear unit. When the optimum tip speed can’t be achieved with the above mentioned mixers, the Verdermix VMP is the right choice for the transition between direct driven and our standard indirect driven agitators.

Applications

Specific Application of Static Mixers

• Neutralisation in waste water plants
• Coagulation in waste water plants
• Homogenisation of low viscous fluids
• Waste water treatment
• Confectionery industry for continuous operation at high speeds in hot and viscous cocoa mixtures
• Mixing fluids of higher viscocities
• Heavy duty applications
• Flocculation treatment
• Reactor vessels
• Homogenisation of solids in liquids

Neutralisation of waste water

In many wastewater treatment plants the water is neutralised by adding caustics and/or acids. By using high speed agitators, eg VNF or VSM, this process will be completed effectively and efficiently. Because the shaft coupling is oitted, type VSM can easily be protected from chemical attack by using non-ferrous-lining or chemical resistant coating over the shaft and mixing elements. The motor bearings can be protected by a non-metallic flange in combination with a sealing ring.

Optimisation surface contact area in flocculants

In flocculation tanks, it is desirable to optimize the surface contact area of flocs and the particles in the threated liquid. However, the floc must not be damaged due to high tip speed. Type Verdermix VFG is ideal for such applications.

Blending of different media in large tanks

Verdermix can easily adjust its direct or indirect driven agitators to side entry mixers. You do not need a heavy mixer with a long mixing shaft with this design. The side entry mixer is mounted sideways on the tank wall. A sealing lantern with mechanical seal is of course needed to prevent any leakage.
