Geared Mixer
To compliment our range of direct drive high speed industrial mixers we offer a geared mixer range which provides high torque slow speed stirring for water treatment, effluent treatment and industrial processes.
The geared mixer range is designed to produce a slow and even mix into solutions and processes which are not suitable for a high speed mixer. This makes them ideal for mixing water treatment chemicals where a low shear ratio is desirable, such as mixers for flocculant and mixers for polymers.
The geared mixer range is also suitable for operation in small dosing tanks as well as large vessels - with a motor range from just 0.09kW right through to 3.0kW with single phase 110 V, single phase 240 V AC and 415 V AC three phase motors available in models throughout the range.
In addition to the standard motors - we can offer geared mixers for hazardous areas with flameproof EX-D motors or mixers with air motors.
Utilising a TEFC (Totally Enclosed Fan Cooled) motor and a worm gearbox, we are able to offer a range of impeller output speeds from 70 RPM, 95 RPM, 140 RPM, 190 RPM and 280 RPM depending upon the application requirements. The gearbox is mounted at 90° to the shaft which enables us to have a low installation height where the ceiling height is restrictive. This particularly useful where a geared mixer is required for a very large chemical storage vessel or process vessel.
In addition to reliability and torque output, our 90° angled worm gearboxes provide a secondary benefit in that the mixer operation is very quiet. When fitted with a single phase motor our geared mixers are significantly quieter.
Polymer Mixer and Flocculant Mixer
Our geared mixer range are designed for polymer mixing and flocculant mixing. They are suitable as a mixer for the preparation of flocculant and polymer or where a flocculant or polymer is used in effluent treatment.
Fitted with a reduction ratio gearbox the flocculant mixers have a low shear co-efficient and the flat bladed impeller ensures that a slow and even mix is achievable without compromising effective surface area of the fluctuant.
Our polymer mixer range have been designed for use both during the flocculant make up stage and during the process stage where gains in fluctuant contact time and efficiency can be achieved.
Geared Mixer for Viscous Solutions.
For processes which require a geared mixer for viscous solutions we have a number of options available within our geared mixer range.
As all of our mixers are manufactured in our Stafford facility in the UK, we take a number of considerations into account when supply a geared mixer for viscous solutions, and are able to offer over-size motors as well as impeller sizes to suit solutions with a viscosity up to ~ 10'000 CPS.
We're also able to increase the number impellers located on the shaft of our mixers to accommodate requirements where viscous solutions are mixed.
Geared Mixer for Lime Solution
For pH neutralisation some customers like to use a lime solution due to the low cost of the chemical and the strong alkaline properties. In these applications keep the solids in suspension is paramount - as the settled lime will literally go rock hard if it drops out.
There are a number of ways of keeping the lime solution in suspension and one of the most cost effective is to fit a small geared mixer to an IBC or dosing tank to prevent the lime from settling. Our range of geared mixers are suitable as lime mixers and can be run continually to ensure that lime settlement is avoided.
Chemically Resistant Geared Mixer
In addition to mixing lime to keep the solids in suspension - our GMW range of geared mixers are available with a PVC coating to ensure that they are suitable for use in chemical processes that react with Stainless Steel.
The PVC coating covers the wetted parts of the mixer including the shaft and impeller giving them a resistant barrier to a number of industrial chemicals. When considering a chemically resistant geared mixer we strongly recommend checking that the chemical is compatible with PVC and if you're unsure - please don't hesitate to get in touch with us.
In addition to our PVC coated geared mixers - we offer a chemically resistant small mixer the AML-9 which is manufactured with a PVC impeller and a PVC coated shaft and is designed to fit on top of small dosing tanks.
