High Energy-Saving Effect with "Estimated End Pressure Constant Control" and "Low-Speed Standby Operation" to Reduce Power Consumption The pump's rotation speed is adjusted according to the water usage, changing in line with the piping resistance to maintain constant end pressure. Additionally, when a cutoff operation is detected for a certain period, the rotation speed is reduced for operation. These features achieve low power consumption and high energy-saving operation, reducing energy use by 10-15% compared to constant discharge pressure control. For more details, please contact us.
