The magnet coupling pump (12) is fitted on the front staged end (14a) of an internal shaft (14) with an axial hole (15) and a flywheel (16) is fitted on the shaft by means of an interposed spring (17) and a nut (18). The flywheel rotates in a spiral housing (20) screwed to the main pump bearing housing (10). To the right of the flywheel is a front slide bearing (22) with a bush (23), outer casing (24) and bearer ring (25). Between the bearer ring and the bush (23) is a spring (26), and outside the outer casing (24) is a tension ring (27). The medium handle (z), viz lubricant and coolant fluid, is conducted through the bearings (22, 29, 22h) of the inner shaft (14) from the flywheel outlet (16a) to the other shaft end (14e) and from there through the axial hole (15) of the inner shaft to the suction chamber.
