Patent ID: 10724547

Abstract:
A cover (1) for a centrifugal pump which comprises a heating element (8), which has a heating stretch (10) and two end stretches (12) connected to the heating stretch (10), wherein the heating element (8) crosses the cover (1) so that the heating stretch (10) is under the cover (1) and the two end stretches (12) are over the cover (1), wherein at least one safety device (20), sensitive to the temperature of the electric resistor (8), fixed to the outer face (6), is provided and at least one control device (22), sensitive to both the temperature of the liquid and the temperature of the electric resistor (8), fixed to the outer face (6), is provided, wherein at least one first portion (14) of the heating stretch (10) is in contact with the cover (1), so that the heating stretch (10) is adapted to be contact with the liquid.
