Abstract (en)

The drive module (4) for a circulating pump has an electric motor (5) with an electronic RPM adjuster and an electronic governor which controls the pump driven by the motor. The electronic governor is designed for at least two circulating pumps which differ in their hydraulic characteristics and is adjustable to correspond to the connected pump. The electronic governor is especially for the circulating pumps of a multi-head pump unit. Parameters for the different pumps are stored or read into the electronic governor at the manufacturers. Independent claims are also included for the following: (A) a pump unit in which the governing of the pump takes place sensor-less and exclusively through the utilization of the electric values of the drive motor; (B) a multi-head pump unit, especially a double pump, with at least two of the specified drive modules; and (C) a circulating pump for the connecting to a drive unit, with a transponder installed preferably on the outer side of the pump housing and through which hydraulic data of the pump are transmitted wire-less to a reading device installed preferably on the motor side.
