<p>#CMT# #/CMT# The pump (1) has a side channel pumping stage (4) comprising running wheels (400) with an edge and vanes (402), where the wheels are displaced during rotation. The vanes exhibit a rear side with an outer edge. The vanes comprise flanges at the outer edge of the rear side. A middle rod is provided between the vanes and other vane. The former vanes comprise two vane sections, which are arranged in a movement direction. The former vanes are arranged at the edge of the wheels in a radial direction. The rear side and the flanges comprise flat surfaces. #CMT#USE : #/CMT# Vacuum pump. #CMT#ADVANTAGE : #/CMT# The vanes comprise flanges at the outer edge of the rear side, thus improving vacuum characteristics value i.e. pressure characteristics, and manufacturing the pump in a simple manner.The flanges are manufactured in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a vacuum pump with a side channel pumping stage in a shaft direction. 1 : Vacuum pump 4 : Side channel pumping stage 20, 21 : Housing parts 400 : Running wheels 402 : Vanes.</p> |
