GMW3

Geared Mixer with 16" Impeller & 0.75kW, 415 VAC Motor

Geared Mixer with 16 inch impeller and 0.75kW 3 phase motor

GMW3 is a geared mixer with a 16" Impeller, driven from a worm gearbox with a 415v 0.75kW motor.


GMW3 Geared Mixer Introduction

The GMW3 is an industrial geared mixer with a 16 inch impeller and 0.75kW motor, designed as a geared mixer for continuous operation in many liquid mixing applications.  These including viscous solutions, and other slow speed stirring and agitation applications in the process control, water treatment and effluent treatment sectors.

The GMW3 has been used for the makeup of pH neutralisation and effluent treatment chemicals and in process applications where the solution has a high viscosity.

The GMW3 is fitted as standard with a 3 phase 415V 0.75kW AC motor. We don't offer a single phase version of the GMW3. If you have an application where the only available power is from a 110V, 240V 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 95RPM.  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 16 inch Impellers

The standard GMW3 utilises a single 16 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.  The GMW3 is also appropriate for 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 16 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 a reduced shearing coefficient, when used as a flocculant mixer.

In addition to fitting a single 16" impeller, the GMW3 is designed to be fitted with additional impellers, depending upon the nature of the vessel and liquid under agitation.  If there is a larger volume of liquid or a large vessel is required with the mixer, then, as an alternative, we offer the GMW31 with a 1.1kW motor.


GMW3 Worm Gearbox Mixer

The 16 inch propellers are directly driven by the worm gearbox.  The shaft is machined at our production facility in 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 the 95RPM and 140RPM versions.

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 16 inch impeller is designed to optimise the stirring capability of the mixer, for a number of different applications.  This makes the GMW3 suitable for use as a geared mixer for viscous solutions as well as for flocculent or polymer makeup.


Geared Mixer GMW3 with 0.75kW 3 Phase Motor

The standard GMW3 is fitted with a TEFC (Totally Enclosed Fan Cooled)  motor and manufactured to IP55 specifications.  The standard motor is a 415 V three phase 0.75kW AC motor.  We also offer a 380 Volt motor and flameproof motors.


GMW3 Chemically Resistant Geared Mixer

For use with process chemicals, we offer the GMW3 with the wetted parts (shaft and 400mm impeller) coated in PVC.  This makes the mixer suitable for mixing applications where the process chemical reacts with 316 stainless steel.

The shaft and 16" 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 to ensure that during the process, 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. 


GMW3 Geared Mixer Features & Benefits

The GMW3 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 GMW3 has been used as an industrial stirrer for viscous solutions as well as for other process applications.  The GMW3 is commonly fitted with additional impellers to ensure an even agitation can be achieved with highly viscous solutions, or where the vessel is large or unusually shaped.  Ideal when used with a single impeller for flocculant make-up as well as a geared mixer for pH neutralisation or other process control applications.

Manufactured in house at our Stafford facility, the GMW3 is available with a number of customised options, depending upon the duty required.  This includes supplying the slow speed mixer with food grade lubricant, additional impellers, a 3 phase 380 VAC motor, flameproof motor, or with a chemically resistant coating.

The GMW3 can be fitted with a second impeller, although for heavier duties we offer our GMW31 geared mixers.

The 16 inch impeller offers efficient mixing and is designed for medium to large sized vessels.  It is suitable for use on viscous solutions, depending upon the level of 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 GMW3 is of proven design and construction, requiring minimal preventative 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.
