The present invention is a pump chamber of the rotary lobe pump, for an area with no fluid in the rotary lobe pump, and particularly relates to a device for sealing the shaft duct area, between the device, labyrinth gap (labyrinth gap) is a closed element has at least two sealing elements, can be disposed adjacent to the front side of the rotary piston disposed on the shaft in the pump chamber of the rotary lobe pump so as to extend the labyrinth gap is said to extend the sealing land (seal land) It is arranged in a radial direction and an axial direction relative to the shaft. According to the invention, the sealing lands, rather than closed Rend in the axial direction of the shaft, it is larger in a radial direction relative to the shaft.
