DEVICE FOR DELIVERING SINGLE-PHASE OR MULTIPHASE FLUIDS WITHOUT ALTERING THE PROPERTIES THEREOF

摘要

The invention relates to a device for delivering single-phase or multiphase fluids without altering the properties thereof. The aim of the invention is to provide a device for carefully delivering single-phase and multiphase fluids which, consisting of a simple construction, does not alter or only insignificantly alters the properties of the fluid to be delivered and, in particular, minimizes dead water zones and turbulences of the fluid to be delivered. The invention provides a device for delivering single-phase or multiphase fluids which is comprised of a tubular cavity (1) that guides the fluid, whereby the rotor (32) of the electric motor is configured as a rotatable delivering part (5) mounted with axial alignment inside the tubular cavity (1). The inventive device also comprises at least one fluid guiding device (7, 7') arranged in front of and/or behind the delivering part (5) and is characterized in that the rotatable delivering part (5) is contactlessly mounted by means of a magnetic bearing.
