GMW2

Geared Mixer with 12" Impeller & 0.55kW, 415 V AC Motor

Geared Mixer with 12 inch impeller and 0.55kW 3 phase motor

GMW2 is a geared mixer with a 12" Impeller driven from a worm gearbox with a 415v 0.55kW motor. 


GMW2 Geared Mixer Introduction

The GMW2 is an industrial geared mixer with a 12 inch impeller and huge 0.55kW motor, designed as a geared mixer for continuous operation in many liquid mixing applications, such as with viscous solutions, and other slow speed stirring and agitation applications in the process control, water treatment and effluent treatment sectors.

The GMW2 has been used for the makeup of pH neutralisation and effluent treatment chemicals, and in process applications where the solution has a viscosity up to 10'000 CPS.

The GMW2 is fitted as standard with a 3 phase 415V 0.55kW AC motor.  We do offer a single phase version of the GMW2 mixer, which is the GMW2-SP2.  If you have an application where the only available power is from a 110V supply or where compressed air is available, then please don't hesitate to get in touch as we may be able to offer alternative solutions.

The standard impeller has a low shear co-efficient making is suitable for flocculent mixing and other applications, and is driven with a speed of 140RPM.  Other output speeds are available, making it ideal for use on a range of Dosing Tanks depending upon the duty, liquid type and viscosity.


Geared Mixer with 12 inch Impellers

The standard GMW2 utilises a single 12 inch impeller which is used to create a continuous stirring motion within the tank or vessel.  This ensures that the solution is under constant agitation from the industrial stirrer making it ideal for keeping lime solutions in suspension as well as other slow speed stirrer applications, such as improving the contact time and reaction potential when used for the agitation of reagent, mixing polymers or the make-up of effluent treatment chemicals.

The 12 inch impeller is not tapered to ensure the industrial stirrer generates a large contact area to provide both a better contact area for more efficient stirring and reduced shearing coefficient when used as a flocculant mixer.

In addition to fitting a single 12" impeller, the GMW2 is designed to be fitted with additional impellers, depending upon the nature of the vessel and liquid under agitation.


Worm Gearbox Mixer GMW2

The 12 inch propellors are directly driven to the worm gear box. The shaft is machined at our production facility in the Stafford, UK to ensure that it is held securely in place within the worm gearbox itself, without a coupling.  This enables us to offer a wide variety of reduction ratios including 70 RPM, 95RPM140RPM and 280 RPM.

In addition to offering a number of gearbox ratio options we machine the shafts and impellers in-house, allowing the shaft length to be manufactured to specification.

Our 3 blade flat 12 inch impeller is designed to optimise the stirring capability of the mixer for a number of different applications, making the GMW2 suitable for use as a geared mixer for viscous solutions as well as for flocculent or polymer makeup.


GMW2 Geared Mixer with 0.55kW 3 Phase Motor

The standard GMW2 is fitted with a TEFC (Totally Enclosed Fan Cooled)  motor and manufactured to IP55 specifications.  The standard motor is a 415 V three phase 0.55kW AC motor.  We also offer a 380 Volt motor and flame proof motors.


Chemically Resistant Geared Mixer GMW2

For use with process chemicals, we offer the GMW2 with the wetted parts (shaft and impeller) coated in PVC.  This makes the mixer suitable for mixing applications where the process chemical reacts with 316 stainless steel.

The shaft and 12" impeller are coated as a single piece to ensure that any fastenings are resistant to the reagents being used in the process.

Any additional impellers are also coated with PVC during the process, to ensure that the whole wet end of the geared mixer offers greater chemical resistance.

We strongly recommend when considering a chemically resistant high speed mixer, that the materials being used are compatible with PVC. 


GMW2 Geared Mixer Features & Benefits

The GMW2 is a geared mixer suitable for a wide variety of applications and unlike our High Speed Industrial Mixers, it doesn't have to be contained within a tank, where the height of the liquid covers the impeller.

Designed for industrial duties, the GMW2 has been used as an industrial stirrer for viscous solutions as well as for other process applications.  The GMW2 is commonly fitted with additional impellers to ensure even agitation can be achieved, even in very viscous solutions or where the vessel is large or unusually shaped.  Ideal for use with a single impeller for flocculant make-up and as a geared mixer for pH neutralisation or other process control applications.

Manufactured in house at our Stafford facility, the GMW2 is available with a number of customised options, depending upon the duty required.  These can include supplying the slow speed mixer with food grade lubricant, additional impellers, a 3 phase 380 VAC motor, flame proof motor, or with a chemically resistant coating.

The GMW2 can be fitted with a second impeller although for heavier duties we offer our GMW21 geared mixer.

The 12 inch impeller offers efficient mixing and is designed for medium sized vessels.  It is suitable for use on viscous solutions depending upon the solution viscosity and volume. If you're unsure on the precise mixer to suit your application, please don't hesitate to get in touch.

The slow speed geared mixer GMW2 is of proven design and construction, requiring minimal preventive maintenance for efficient low shear mixing.  It is suitable for a wide range of applications including mixing water treatment chemicals and for mixing in process applications.
