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
Twelve different performancecurves can be selected by one-touch operation. In addition to the four characteristics which operate according to the proportional pressure method, four further can be selected with a constant characteristic curve as well as four with a constant pressure characteristic.
