Large pump for use as mammoth pump to transfer water from e.g. buried water basin to heating equipment for building, has plate heating insulator thermally insulating suctioning and pumping pipe with valve and/or vessel with suction pipe

摘要

The pump has a hermetically closed fluid sealed container (1) including a flat container lid and an expansion vessel, which is designed with a lifting drain or siphon drain or suction pipe (3). The vessel is arranged at higher height than the lid. A suctioning and pumping pipe (6) with a valve (7) and/or the vessel with the lifting drain, siphon drain or suction pipe are thermally insulated by a plate heating insulator (8). A suctioning and pumping pipe (4) includes a valve (5) with an element for supplying hydraulic fluid from a water basin and a water container. An independent claim is also included for a heating equipment for a building and a plant with heated air through a smoke duct and a heating pipeline in walls.
