<p>A device for pumping paint comprises a pump house adapted to receive paint from a paint source, a pump shaft (8) for driving a pump member to rotate inside the house for pumping paint therethrough. The pump shaft is through an intermediate shaft piece connected to an output shaft (10) of a motor arranged outside the pump house through a wall of the pump house, said motor being arranged to drive the pump shaft and thereby the pump member. A sealing member (12) is arranged to counteract that paint leaks out of the pump house along the pump shaft. The sealing member is arranged to bear substantially axially sealingly against substantially axial surfaces (13) of the pump shaft around this shaft, in which the sealing member and/or these axial surfaces are of a ceramic material.</p> |
