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.
