Abstract

The liquid is pumped by a pump rotor (6) through an annular duct (4) upwards to an outlet (5). Not far above the rotor (6), a leakage duct (21) emanating from a supporting tube (2) surrounding a rotor shaft (7) is passed through the annular duct (4) in a sealed manner. Leakage fluid from the supporting tube (2) can thus be returned to the supply of liquid within a container, e.g. a drum, so that any contamination of the supply is avoided.
