Duo-mix 2000 Si FE Self Levelling Screed Mixer Pump. This special feature enables the duo-mix to guarantee the best homogeneous mortar screed quality, even with those products that are more difficult to mix, like certain construction chemicals, for example. The duo-mix 2000 version in particular has an output that can be continuously adjusted to suit the application, making it particularly suitable for special products. Both versions allow long pumping distances to be achieved.

The areas of application of the duo-mix are very varied. In addition to working as a mixing pump, it can also be converted into a continuous mixer or a mortar pump for processing soft materials. Conversion can be carried out in a few simple steps.

The duo-mix can be fed with bagged material, silo material (in conjunction with an m-tec silo, conveying system and filter hood) as well as with bucket coat materials.

As is typical of all m-tec systems, the duo-mix has easy and quick to use tensioning wedges, enabling important elements such as the worm pump or mixer motor to be replaced in just a few seconds.

Our patented mixing principle
The duo-mix can process all standard dry mortar products up to a grain size of 4 mm. The technical highlight of the duo-mix is the transfer of material from the dosing area to the mixing area – the water is no longer simply sprayed at the dry material as in the past, but is instead dosed according to a patented mixing principle, that sprinkles it into a pool of water and then mixed. The result: the construction materials are blended even more effectively and the additives take full effect. This all guarantees the first-class processing of the materials.
Easy Work
Our intelligent machine technology allows you to work without interruption and without thick/thin variations. The separation of dry and wet areas enables a constant ratio of dry material to water to be achieved.

Easy Mix
The particularly good mixing quality is made possible with our patented mixing system. When used in conjunction with double mixing, the system guarantees the best possible mix of mortar products.

Easy Use
A combination of clearly laid-out controls, self-explanatory flowchart control with error code display (duo-mix 2000 only), lifting handles and tensioning wedges make the duo-mix easy to handle.

Easy Life
Thanks to the particularly long conveying distance that can be achieved, there is no need to waste time and effort relocating the duo-mix. Your gain: more effective working time!

Easy Handle
The duo-mix can be used as a mixing pump, continuous mixer or mortar pump. Together with the continuous regulation of output (with the duo-mix 2000 only) you also get the functions only otherwise available with an entire fleet of machines!
