duo-mix - the Queen of the construction site!

Excellent blending and tremendous adaptability for a wide variety of materials are the key properties offered by the duo-mix. The reasons for this: the unique m-tec dual mixing system with two-way blending together with the patented mixing principle - combined make a combination that no other mixing pump on the market can offer!

This special feature enables the duo-mix to guarantee the best homogeneous mortar quality, even with those products that are more difficult to mix, like certain construction chemicals, for example. The duo-mix2000 version has an output that can be continuously adjusted to suit the application, making it extraordinarily well-suited for special products. Both versions have very long pumping distances.

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

The duo-mix can be fed with bagged material, silo goods (in conjunction with an m-tec silo, conveying system and filter hood) and with soft materials.
As is typical of all m-tec systems, the duo-mix has easy and quick to use tension 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 material transfer from the dosing section to the mixing section: the water is not sprayed at the material as in the past, instead dosed according to a patented mixing principle, that sprinkles it into a pool of water and then mixes. 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 building materials.



duo-mix - added benefits

Easy Work

Our intelligent machine technology allows you to work uninterrupted and without consistency changes. The separation of the dry and wet sections enables a constant ratio of dry material to water.

Easy Mix

Our patented mixing system enables an extremely good mixing quality. When used in conjunction with the two-way blending, the system guarantees the best-possible mix of mortar products.

Easy Use

A combination of clearly laid-out controls, self-explanatory flowchart control system with error code display (only on the duo-mix2000), 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 (only for the duo-mix2000), you also get the functions only otherwise available with an entire fleet.
