Abstract (en)

The pump has collar-like sections (21,26,31,36) provided on the suction side and/or on the pressure and conveyance side by means of which the pump can be welded gas-tight with other components. An assembly (13) is provided in or on the pump housing to heat the pump and the fluid passes through this assembly. The pump has a partially double-walled housing (1) for forming the interspace (13) through which the fluid passes. One or more connecting openings (16) with the interspace are provided in the welding section areas so that the heating medium can be supplied and discharged.
