Zusammenfassung:	FIELD: automotive industry and allied industries for pumping liquids at low and critical temperatures. SUBSTANCE: pump has sectional housing, impeller and bushing. It has also shaft, gaskets, threaded members, pin, washers and flange. Impeller is assembled with stepped ring shaft. Shaft is provided with riffles on small ring projection and it has end face with blind hole at other side. Shaft end face interacts with rubber collar accommodating graphite ring. Surface of second graphite ring arranged opposite to first ring is designed for taking up axial loads from movable graphite ring. Movable graphite ring is flexible held on end face of driven shaft. Impeller is installed on shaft riffles and is made of strong heat resistant materials. EFFECT: increased service life, simplified design of friction pair and provision of interchangeability of parts. 8 dwg
