FIELD: mechanical engineering. SUBSTANCE: invention can be used for liquid cleaning of automobile window glasses. Proposed pump has housing with working chamber accommodating impeller whose edges form clearance to let liquid pass to outlet nozzle. Shaft of electric motor rotor has axial coupling with impeller hole. Impeller consists of two working sections, one designed for creating gauge pressure, and the other to let liquid flow out of nozzle. Nozzle is made in form of cylindrical boss provided with hole and arranged on housing. Axis of hole intersects axis of pump housing. Housing is made of plastic material and is provided with suction nozzle. The latter is provided with radius grooves from side of end face for sucking in liquid. Material of pump housing is polyamide, grade ПA66-KC, and impeller is made of material, grade ПA610-Л-Г5. EFFECT: increased efficiency of transfer of liquids at short-time metered out deliveries at speed of rotation of electric motor rotor from 8 to 16 rpm. 4 dwg
