Pump with temperature and speed sensor

摘要

The pump (1) includes a drive (2) which drives a pump impeller (3), and a separating wall (4) arranged between the pump impeller and the drive. A sensor (9) for the number of revolutions is arranged on the side of the separating wall facing the drive, in the area of the pump impeller. The number of revolutions sensor is electrically connected by an electric conductor (7) with a control mechanism (10) of the pump. A temperature sensor (15) is also connected to the conductor, whereby the temperature sensor is forced by a spring (F) against the separating wall or a heat bridge which is in thermic connection with the separating wall.
