Geared Mixer with 10" Impeller 110v, 0.25kW AC Motor

GMW1-SP1 Geared Mixer with a 10 inch Ø flat bladed impeller, fitted with a single phase 240v 0.25kW AC motor and worm gearbox.

GMW1-SP1 Geared Mixer Introduction

The GMW1-SP1 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 where a 3 phase supply is not present.

The GMW1-SP1 is ideal for 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-SP1 is fitted as standard with a single phase 110v 0.25kW AC motor.  We do offer a three phase 415V three phase version of the GMW1-SP1 which is the GMW1 fitted with a 415v three phase 0.25kV AC motor and we also offer a 240 volt single phase version with 0.25kW motor the GMW1-SP2.

All of the GMW1 slow speed stirrers utilise a reduction ratio worm gearbox to drive a 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, thus 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-SP1 features 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, so making it ideal for keeping lime solutions in suspension as well as other slow speed stirrer applications. These include improving the contact time and reaction potential when used for the agitation of reagents, 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 to provide both a better contact area for more efficient stirring and reduced shearing coefficient when used as a flocculant mixer.

GMW1-SP1 Worm Gearbox Mixer 

The 10 inch impeller 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-SP1 suitable for use as a geared mixer for viscous solutions as well as for flocculent or polymer makeup.

Geared Mixer GMW1-SP1 with 0.25kW 240v Single Phase Motor

The standard GMW1-SP1 is fitted with a TEFC (Totally Enclosed Fan Cooled) motor and manufactured to IP55 specifications.  The GMW1-SP1 uses a single phase 110v 0.25kW AC motor.  Flameproof motors and hygienic motor types are available for hazardous or food & dairy applications, as well as a 240V AC single phase version.

GMW1-SP1 Chemically Resistant Geared Mixer 

For use with process chemicals, we offer the GMW1-SP1 with the wetted parts (shaft and 250mm impeller) coated in PVC.  This makes the mixer suitable for mixing applications where the process chemical reacts with 316 stainless steel.

The shaft and 10" impeller are coated as a single piece to ensure 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-SP1 Geared Mixer Features & Benefits

The GMW1-SP1 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 light and medium industrial duties where the supply voltage options are limited, the GMW1-SP1 can be used for stirring viscous process solutions and for flocculant or polymer make up tanks, as well as other processes and applications.

Manufactured in house at our Stafford facility, the GMW1-SP1 is available with a number of customised options, depending upon the duty required, including supplying with an additional impeller, food grade lubricant, 3 phase 380 VAC motor, flame proof motor, or with a chemically resistant coating.

The GMW1-SP1 can be fitted with a second impeller, although for heavier duties we would suggest considering Model GMW11-SP1 as a geared mixer for use with a single phase 110 VAC supply.  If 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 available, PVC coated, for greater chemical resistance.  Designed principally for smaller vessels and process 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-SP1 is of proven design and construction, requiring minimal preventive maintenance for efficient low shear mixing.  The design offers slow speed agitation for numerous applications such as mixing water treatment chemicals and for mixing in process applications where a three phase supply isn't present.
