A good pumping system can eliminate unnecessary losses, reduce energy consumption and improve the reliability of the system. In addition to a reasonable choice of pump type to work reliably at the optimum efficiency point, choosing energy saving products matching with pump are very beneficial for the low energy operation of the entire system. We recommend permanent magnet motors and VFDs to you . Permanent magnet motors are more efficient than conventional motors, and the Variable Frequency Drives (VFDs) are more energy efficient than other pump speed adjustments.
