Verdermix dynamic mixers, stirring and mixing fluids

The Verdermix agitator consists of a drive (motor), a shaft (available from 500 – 1800 mm) and a mixing element. The energy of the drive is transferred into the fluid by means of the mixing element located at the end of the mixer shaft. The fluid is being whirled by the energy produced through the motor. Whirling is necessary for suspending, dispersing and gassing the medium. The shape of the mixing element(s), the position in the tank and the shaft speed create the end result.

Models

VNF: The VNF dynamic mixer model has shaft speeds between 750 and 1800 rpm. The electric motors, which are constructed to the IEC code are for light duty service. The VNF stirrer can be fitted with shaft seals, lanterns with stuffing boxes, plastic linings or coatings for resistance against aggressive chemicals. Additional fixed or moving support frames can be constructed to the customer’s specifications and requirements.

VSM: Shaft speeds between 750 and 1800 rpm. This Verdermix agitator uses a special electric motor with a hollow shaft. The robust mixer shaft is fixed with both a conical and cylindrical fit. The most notable characteristic of this heavy duty agitator is its robust and stable design.

VWM/VFG: Verdermix models with stirrers which have shaft speeds between 30 and 200 rpm and are equipped with a worm gear (VWM) or parallel shaft gear (VFG). This range of mixers are particularly suitable for when mixable products require blending with great care and intensity. Large gearboxes are specified which contain an extra step in gears in order to reduce loads and to guarantee a long life span.

VPM: The VPM agitators have shaft speeds between 120 and 1800 rpm. This type of Verdermix mixer is driven through a gearbox. The driver can be equipped with an internal frequency control and may be operated by a simple potentiometer on the e-motor or a small panel at a set distance from the unit.
