In an average household 10 to 20% of the electricity consumption is caused by using a conventional standard pump. With our series WITA go.future 2 we have developed a circulating pump which shows an energy efficiency index of ≤ 0.20. By using these pumps the energy consumption can be reduced by up to 80% – compared with a conventional circulation pump. The hydraulic power is almost equal to the standard pumps. The pump capacity adapts to the actual requirements of the system because it is working according to the proportional pressure method.
