Abstract

The pump assembly, for pumping fluids, has a metal housing (2) with a drive shaft (1) to carry a number of running wheels (6) at axial intervals. The wheels lie between ceramic intermediate walls (3a-3c), supported at the housing by elastic equalizing units (5d-5i), of a fluoroelastomer material, as O-rings and flat seals.
