ABSTRACT:
A multiple-function pumping device includes a pump for supplying at least one jet, an electric motor with a stator and a rotor for driving the pump, and circuitry for electrically connecting the motor to a main voltage power supply line. The stator is provided with an excitation winding. The stator has electrical circuit components for powering an external lighting device with low voltage. Preferably, the low-voltage powering circuit components include an electric transformer having as a primary circuit the excitation winding of the motor and further include a secondary circuit which is also wound around the stator.
