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