Abstract (en)
[origin: EP1247993A2] Pump has a pump housing (3) with a pump chamber (11) arranged in a rotationally symmetric manner about an impeller (6). A diffuser chamber (13) is arranged downstream from the impeller chamber to change a part of the flow speed into pressure. Downstream from the diffuser is a pressure chamber (14) in which the flow is calmed prior to delivery to a number of pressure branches (5, 5') which branch off from the chamber. A heater (2) is contained within the pressure chamber.
