Abstract
The present invention relates to a fluid pump that comprises a housing having an inlet opening for receiving the fluid, an outlet opening for discharging the fluid and enclosing an impeller rotating inside the housing to pump the fluid from the inlet opening to the outlet opening and a motor assembly to drive the impeller. The housing is shaped to establish a single turn volute of 360° turn angle providing a first conveying channel located peripherally around the impeller from a fluid entry point at 0° turn angle to a fluid exit point at 360° turn angle of the single turn volute being connected to the outlet opening. The first conveying channel has a first cross section area in radial direction perpendicular to the rotational plane of the impeller, where a size of the first cross section area increases as a monotonic increasing function of the turn angle between entry point and exit point.
