Emotron DCM automatically adjusts pump operation to water flow, without external water level sensors. It also prevents dry-running and other damage, reducing maintenance and downtime. Typical applications are drainage on construction sites, in quarries and mines. Optimizes pump operation Emotron DCM immediately stops the submersible pump when it starts to draw air because of a lack of water, and restarts it when there is water again. Pump operation is adapted to water flow, minimizing energy and maintenance costs.
