Abstract
A heating and pumping device for liquids, in particular for water of aquariums, the device comprising a pump (24) having a pump body (32) and a thermo-heating element (26) having a thermo-heating body (60). There is a casing (22) which contains both the pump (24) and the thermo-heating element (26) such that a passage section (102) for water is defined between the thermo-heating element (26) and the casing (22). To seal the electrical parts of the thermo-heating element (26) and to prevent damage, a sole sealed zone (100) filled with resin is created between the pump body (32) and the thermo-heating body (60). This resin filled sole sealed zone (100) obviates the need for using other less effective sealing elements and gaskets.
