Abstract

The pump rotor (3) is made of rigid material and is driven by an electric motor. To reduce the motor starting current, the lining (5) is prestressed at 5 to 15% against the rotor. The lining surface (8) bearing against the rotor contains a fine structure between protrusions (15), so as to accommodate liquid or pasty ingredients in the medium handled. The protrusions can be formed by rounded bosses, and the structure can resemble flakes nesting together. The protrusions can be in rows one behind the other, those in adjacent rows being offset for half the intervals between them.
