Abstract: The present invention relates to a fluid pump having an improved performance. The pump comprises an impeller, volute housing, inner housing geometry, and an adapter. The impeller is configured to generate fluid flow velocity. The volute housing is configured to improve fluid pump performance while reducing power consumption, the volute housing comprises the inner housing geometry. The inner housing geometry is configured to convert the fluid flow velocity that has been generated into pressure. The adapter is designed to protect the unconnected end of the drive shaft and reduce the negative effects of shaft deflection. The adapter also has a structural rib geometry which is configured to provide superior structural integrity at a minimal mass.
