TANK MIXING
A BETTER MIX - WITH ROTAMIX AND STM SYSTEMS
Tank 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

INNOVATIVE, SMALL TANK
MIXING SYSTEM CUTS COSTS
‘Rag wrapping’ problems at sewage treatment sites can cause expensive, time-consuming maintenance.
System Mix, (P&M Pumps mixing system design and supply company), can help you overcome these problems.
Take a look at our standard STM (Small Tank Mixing) system technoloygy.

The Concept
The 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 Mixing
The dual-zone mixing pattern is a combination of both uniform
and vortical fields of flow. In a uniform field of flow, the
entire contents 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 more
steady, so solids are prevented from settling in the centre. |

Induced Flow
High 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 Contact
Finally, 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. |
