Abstract
A device for pumping paint includes a pump house adapted to receive paint from a paint source, a pump shaft for driving a pump member to rotate inside the house for pumping paint therethrough. The pump shaft is connected to an output shaft of a motor arranged outside the pump house through an intermediate shaft piece through a wall of the pump house. The motor is arranged to drive the pump shaft and the pump member. A sealing member is arranged to counteract paint leaking out of the pump housing along the pump shaft. The sealing member is arranged to seal by bearing substantially axially against substantially axial surfaces of the pump shaft around the pump shaft, in which the sealing member and/or these axial surfaces are preferably of a ceramic material.
