A BETTER MIX - WITH ROTAMIX AND STM SYSTEMSTank mixing is an important requirement in many waste water and process applications and the Vaughan Rotamix System and STM (Small Tank Mixing) are acknowledged as the most cost-effective methods of mechanical mixing available today.

Take a look at the key benefits:

Low cost, effective means of mixing any size tank

Easily maintained. No internal mechanics Uses Vaughan Chopper Pump at the heart of

the system Effective in circular, square and rectangular

tanks Guaranteed mixing

Computerized flow models optimize mixing

THE CONCEPTThe Rotamix system incorporates several basic principles of physics and hydraulics, including uniform field of flow, vortical field of flow and surface contact. This combination of this unique mixing system optimises solids contact due to the homogeneous state.

DUAL-ZONE MIXINGThe dual-zone mixing pattern is a combination of both uniform and vortical fields of flow. In a uniform field of flow, the entire content rotates as a solid unit with the highest velocity at the outside. In a vortical field of flow, fluid velocities are the greatest at the centre, which creates a vertical-axis vortex. The Rotamix system combines both uniform rotation and a vertical vortex, creating unique dual-rotational zones. With dual-zone mixing, average velocities are higher and steadier, so solids are prevented from settling in the centre.

INDUCED FLOWHigh velocity nozzles also increase the effective mixing volume by inducing entrained fluid, significantly increasing the overall mixing effect. These high velocity nozzles induce flow over a longer distance, thus generating an overall effect over a larger volume.

SURFACE CONTACTFinally, the Vaughan Chopper Pump not only eliminates nozzle clogging, but also optimises surface contact by constantly reducing solids size and so increases total surface area.
