Electromagnetic Eddy Current engineering is simply better by design. When compared to VFDs, especially in medium voltage water and wastewater applications, Dynamatic adjustable speed pump-drive systems can save you up to 65% in capital costs alone. The operating efficiency of a Dynamatic adjustable speed drive increases relative to the normal operating speed of a motor, making them ideal for water and wastewater pumping applications. Rugged and reliable, Dynamatic® adjustable speed drives and digital controls are simple to maintain and have been proven to outlast VFDs by as much as 6:1.
