The WITA® high-efficiency circulating pumps are characterized by a high quality “Made in Germany”. By using high-grade materials, our products are designed for a long service life. Because of our own production in the Bad Oeynhausen (Germany), we can ensure efficient structures, our quality standards, the requirements of craftsmanship and fair prices.
As a material, WITA® processes cataphoresis-coated armature castings and chromium-nickel steel. These proven materials guarantee high resistance and a versatile range of applications. All circulating pumps are supplied with heat insulation shells, seals, coupling plugs or permanently installed cables.
In an average household, 10 to 15% of the electricity consumption is caused by conventional standard pumps. Through the use of the WITA® high efficiency pumps the energy consumption can be compared to a conventional circulation pump. Approximately 80%.
The hydraulic power could be almost kept the same compared to standard pumps.
Special features / Product advantages
With this pump, eleven different performancecurves can be selected. In addition to the six characteristics which operate according to the proportional pressure method, five further can be selected with a constant characteristic curve. Through the switchable night reduction, the power consumption can be reduced once the system temperature has been lowered. The LCD display shows the current power consumption, the selected characteristic curve and the night reduction.
