High efficiency circulation pump WITA go.future 2 40-25 180 LED

In an average household, 10 to 20% of electricity consumption is generated by a conventional standard pump. In our WITA go.future 2 series, we have developed a circulation pump with an energy efficiency index ≤ 0.20. By using these pumps, energy consumption can be reduced by up to 80% compared to a conventional circulation pump. The hydraulic performance is almost the same as that of standard pumps. The pump output adjusts to the actual needs of the system because it operates according to the proportional pressure method.
