Precise working with an overhead stirrer depends on the right choice of the stirrer tool. When choosing a stirrer tool you have to consider its different characteristics and their effects: For example, the flow which the tool causes in the medium, the tool´s adequate field of application depending on the speed range, and the execution of the tool according to the viscosity it is destined for

Application examples:

  • Gassing of liquids < 500 mPa s: Radial Flow Impeller
  • Homogenizing and suspensing in liquids < 500 mPa s:
    Propeller-Type or Blade Impeller
  • Medium with a viscosity > 500 mPa s:
    Anchor-Type Impeller, Blade Impeller BR 13, VISCO JET®
  • Stirring, of gel: VISCO JET®

Please ensure that for radial flow, blade, half-moon and VISCO JET® impeller the beaker size and position of your impeller complies with the guidelines below to achieve superior mixing results

Position of the stirring tool

  • In center
  • Distance to the bottom (h3/d2): 0.3
  • Diameter vessel (h1/d1): 1
  • VISCO JET® Ø ratio (d2/d1): 0,4 - 0,6


Circumferential speed

  • 3 - 15 m/sec: Radial Flow Impeller
  • 2 - 5 m/sec: VISCO JET®, Blade and Anchor-Type Impellers

The all-rounder for thick and thin

• Reduce your process times significantly while performing the best mixing results ever

• One system for literally all mixing tasks for low to high-viscosity media

• The turbulent flow which is created by a special cone principle even at low speeds is unique to the VISCO JET®

• Even with high-viscosity media and gels which naturally do not mix when common impellers are used you will observe an immediate flow through the entire beaker

• This technology allows for de-gassing of gels while preventing air intake and foaming


Application examples

The only impeller world wide capable of completely mixing larger quantities of high-viscosity liquids and gels Fields of use:

Beverage production, dairy products, food, sugar & candy production, chemistry/petro chemistry, ceramics, water treatment, cosmetics, colorant/paint production and paper manufacture, etc.

Principle of functionality

The VISCO JET® Mixing System from VISCO JET Rührsysteme GmbH 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
