Abstract (en)
[origin: EP0731280A1] The pump assembly has a rectilinear force flow (6) between the pump part (1) and motor part (2). A force-transferring insulating single or multi-part ceramic element is mounted in the force flow in the heat barrier (3). The ceramic element can be ring shaped. A space (12.1) filled with ceramic insulating material (12) is located between the ceramic element (5) and a shaft (9) connecting the pump and motor parts. Between the space and shaft the heat barrier can be provided with a thin-walled pressure-resistant gas-tight shaft passage (10).
