    摘要: A pump for liquids at positive pressure, includes a pump chamber (18) accommodating an impeller (24), wherein the impeller (24) is axially biased against a non-rotating support element (48) which determines the axial position of the impeller (24). The shaft (42) may be coupled to a drive shaft (64) through a magnet coupling (56, 62).

    摘要: A method of detecting leakage in a pump (10) that has at least one displacement body (12) for displacing a medium to be pumped into a pressure line (20), the method including the steps of: a) closing-off the pressure line (20), b) operating the pump (10) with a known speed of the displacement body (12), c) measuring the pressure (P) in the pressure line (20), d) repeating the steps b) and c) with different speeds, and e) recording the dependency of the measured pressure from the speed, wherein the speed of the displacement body (12) is program-controlled to increase, starting from a minimum speed, gradually to a maximum speed, the maximum speed being calculated on the basis of the measured pressure rise.
