Stirrer Heads

This novel stirring system has been conceived to mix low viscosity fluids as well as highly viscous media at slow speeds. Its special design creates inherent dynamic currents to produce perfectly homogeneous mixing results in very little time. Additional components like baffles, bottom bearings, etc. are not needed.

Advantages at a glance:

• suitable for low to highly viscous fluids
• stirs media containing solids and fibres without any difficulty
• gentle, low-shear stirring, due to slow stirring speed
• constant product temperature, with no heating effect
• short mixing times as the entire contents of the container are agitated
• no air addition, no foaming
• no baffles required
• low gear wear due to balanced forces
• minimal power consumption thanks to low speeds and short operation times
• easy cleaning
• material no. 1.4404

• a single stirring zone, near to the container base, ensures easy mixing of settled residues, e.g. in flow-through mixing containers
• no baffles required, thus no additional sources of ignition

The folding blades of this 2-blade centrifugal stirring rotor open with increasing speed, allowing use with narrow-neck vessels. The stirring effect it provides is similar to a standard diagonal blade stirring rotor. Recommended for medium to high speed operations.

The dissolver stirring rotor creates a radial flow with high turbulence. The mixture is drawn from top to bottom. High shear forces are created at the dissolver disk, which provides effective particle reduction. Recommended for medium to high speed operations.

The worldwide patented VISCO JET^® Mixing System is the result of the so-called cone-principle. Turbulent flows are created at the taper end by acceleration, displacement and retardation. These flows advance through the stirred medium and result in the new dynamic mixing motion.

• One system for literally all mixing tasks for low to high viscosity media
• Patented cone-principle creates even at low speeds a turbulent flow which is unique to the VISCO JET^®
• Even with high-viscosity media and gels which naturally do not mix by using common impellers you will observe an immediate flow through the entire beaker
• This technology allows for de-gassing of gels while preventing air intake and foaming
• Reduce process times significantly while performing the best mixing result ever

Generates axial flow. For drawing the material to be mixed from above. For circulating and handling low to medium viscous liquids. Recommended for medium speed operations.
