Heidolph Overhead Stirrer Visco Jet Crack Impeller- 120mm (Stainless Steel)
Particularly in the case of applications with very viscous media such as pastes and gels, a very reliable stirring process in the entire vessel without air entry is important. This is what the innovative stirring system VISCO JET® offers!
The particular shape of the blades triggers an intrinsically dynamic flow, which shortens the process times with significantly better mixing results compared to conventional impellers. An all-rounder for aqueous and highly viscous substances. You can find out more about this here.
The VISCO JET® Crack 120 is ideal for vessels with the following characteristics:
- ideal vessel diameter: 200- 300 mm
- ideal ground clearance: 36 mm
- ideal filling level: 200- 300 mm
- ideal volume: 6,300 - 21,200 ml
The VISCO JET® Crack 120 is made of stainless steel
A stirrer shaft with a diameter of 10 mm is included in the scope of delivery.
Patented Operating Principle
The VISCO JET® stirring system works on the basis of the so-called cone principle. The dynamic pressure at the displacer inlet and an accelerated flow inside the displacer generate turbulence (so-called nozzle effect). These turbulences collide during the circular movement of the stirring tool and lead to the revolutionary stirring movement. The cone pieces were built in a sophisticated angular ratio, so that they complement each other optimally in terms of flow behavior and thus an additional stirring effect is achieved.
Ideal Speed Ranges
The circumferential speed for the VISCO JET® stirring tool is between 0.5 and 2 m/sec. With low-viscosity media, 0.5 m/sec. is sufficient, with high-viscosity media a speed of 2 m/sec. is more likely to be required. So that you can use our VISCO JET® stirring tool in the best possible way, we will give you the speeds achieved. You can vary in these range. If the medium is highly viscous, the speed can be increased by about 10 -15%.
Blades diameter: 120 mm
Speed range at approx. 0.5 m/sec.: 120 rpm
Speed range at approx. 2 m/sec.: 500 rpm
You can also make sure of the ideal speed of your stirring tool by ensuring that there is only a minimal formation of thrombi on the surface of the medium that no air is drawn in. At a low speed, the medium can even be degassed.
Foam formation is also avoided at the speeds indicated above.
