Proven, durable adjustable speed for pumping
Dynamatic eddy current drives, clutches, brakes and controls deliver reliable variable speed for municipal water and wastewater systems — with simpler electronics, lower installed cost and decades of service life.
- Up to 65% lower capital cost than medium-voltage VFDs
- Drives that outlast VFDs by as much as 6:1
- Electronics 60–70% smaller than comparable MV VFDs
- Continuous operation in 104°F ambient environments
- Unaffected by the power quality fluctuations that damage VFDs
