Clip & Work Especially in   the operation at partial loads of a centrifugal pump there will be significant potential of energy savings! „TÜV-approved” Example: Circulation pump with nominal power in partial load operation. Power consumption as per curve Saving per 1/3 year (2.920 hours) Pump at constant speed Pump at variable speed Energy savings within 1 year (8.760 hours) Compared with the installation costs for the HYDROVAR units there will be a payback time of less than one year (depending of the energy costs).
