Geared Mixer with 10" Impeller and 0.25kW Motor

GMW1 Geared Mixer with a 10 inch Ø flat bladed impeller fitted with a 3 phase 415V 0.25kW AC motor and worm gearbox.

GMW1 Geared Mixer Introduction

The GMW1 is an industrial geared mixer with a 10 inch impeller, designed for slow speed stirring and agitation.  The geared mixer is designed for agitation and stirring applications in process control, water treatment and effluent treatment, including the makeup of pH neutralisation and effluent treatment chemicals, such as a flocculent mixer or polymer mixer, as well as a mixer for keeping lime in suspension for pH correction applications.

The GMW1 is fitted as standard with a 3 phase 415V 0.25kW AC motor.  We do offer single phase versions of the GMW-1 including the GMW1-SP2 fitted with a 240 V single phase 0.25kV AC motor and the GMW1-SP1 which is fitted with a 110 V single phase 0.25kV AC motor. Each of the single phase versions drive a reduction ratio worm gearbox to run the 250mm impeller (10 inch impeller).

The standard impeller has a low shear co-efficient and is driven with a speed of 140RPM, with other output speeds available, making it ideal for use on a range of dosing tanks depending upon the duty, liquid type and viscosity.

Geared Mixer with 10 inch Impeller

The GMW1 utilises a 10 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 10 inch impeller is not tapered to ensure the industrial stirrer generates a large contact area, providing both a better contact area for more efficient stirring and reduced shearing coefficient when used as a flocculant mixer.

GMW1 Worm Gearbox Mixer 

The 10 inch propellor is directly driven to the worm gearbox.  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, 95RPM and 140 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 10 inch impeller is designed to optimise the stirring capability of the mixer for a number of different applications.  This makes the GMW1 suitable for use as a geared mixer for viscous solutions as well as a geared mixer for flocculent or polymer makeup.

Geared Mixer GMW1 with 0.25kW 3 Phase Motor

The standard GMW1 is fitted with a TEFC (Totally Enclosed Fan Cooled)  motor and manufactured to IP55 specifications.  The standard motor is a 415 V three phase 0.25kW AC motor.  We also offer a 380 Volt motor, flame proof motor, 110 VAC single phase motor or 240 VAC Single phase motor.

GMW1 Chemically Resistant Geared Mixer

For use with process chemicals, we offer the GMW1 with the wetted parts (shaft and 250mm impeller) coated in PVC.  This makes the mixer suitable for mixing applications where the chemical to be coated reacts with 316 stainless steel.

The shaft and 10" impeller are coated as a single piece which ensures that any fastenings are resistant to the reagents being used in the process.

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

GMW1 Geared Mixer Features & Benefits

The GMW1 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 with a tank where the height of the liquid covers the impeller.

Designed for light and medium industrial duties, the GMW1 has been used as an industrial stirrer for keeping lime solutions in suspension as well as a geared mixer 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 GMW1 is available with a number of customisation options, depending upon the duty required.  As well as the 110 VAC and 240 VAC SP1 and SP2 versions, we offer the GMW1 with variations such as an additional impeller, Food Grade lubricant, 3 phase 380 VAC motor, flame proof motor, or with chemically resistant coating.

The GMW1 can be fitted with a second impeller although for heavier duties we would suggest considering the GMW11. I f you are considering a specific customisation for use with your process, or if you're unsure then please get in touch.

The 10 inch impeller offers efficient mixing and is designed for smaller 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 GMW1 is of proven design and construction requiring minimal prevent ive maintenance for efficient low shear mixing.  Suitable for a wide range of applications including mixing water treatment chemicals and for mixing in process applications.
