Duo-mix 2000 Si
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!
