DOPAG has added two progressive cavity pump systems for 1K and 2K materials to its product range: rotordis for processing single-component materials, and rotormix for metering and mixing multi-component materials. Rotordis and rotormix are each available in four different nominal sizes: 0.01, 0.05, 0.15, and 0.30 ml/U. Rotordis enables shot sizes from 0.002 ml (2 μl) to be processed at a discharge rate of 0.13–45 ml/min, while rotormix enables shot sizes from 0.006 ml (6 μl) to be processed at a discharge rate of 0.26–90 ml/min. In both cases, this is dependent on the viscosity and, in the case of rotormix, also on the mixing ratio.

Metering precision is ±1%. With rotordis and rotormix, materials with different viscosities can be processed, ranging from water-thin to highly viscous or pasty. Depending on the viscosity, cartridges, pressure tanks, or barrel pumps can be used. With both systems, application is generally carried out directly from the metering system onto the component by means of a nozzle or mixing tube. A DC drive enables dynamic metering and a controllable back suction effect. A specially developed electronic metering control unit ensures optimal adaptation of all application-specific parameters. In addition, straightforward integration into automated production processes is ensured thanks to a standardized interface.
