摘要：: #CMT# #/CMT# Steam vacuum pump comprises a pump head with a head plate and an intermediate plate with circular support surfaces (6) running planar and parallel with the planar surface (12). Annular cutting edges (9, 10) are arranged central to a pin axis on the planar surface and have a passage (13) between them. Valve plates (4) are arranged with play between the cutting edges and the support surface. #CMT#USE : #/CMT# Used in medical technology for evacuating sterilization devices. #CMT#ADVANTAGE : #/CMT# Water does not collect in the pump chamber or pump head. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-section through the steam vacuum pump. 4 : valve plates 6 : support surfaces 9, 10 : cutting edges 12 : planar surfaces 13 : passages #CMT#POLYMERS : #/CMT# Preferred Materials: The valve plate is made from peroxidized crosslinked EPDM. The valve plate has a Shore hardness of 60-80[deg] C.
