PUMP FOR LIQUID WITH A DENSITY MORE THAN 1 KG/DM3

摘要

Pump for liquid with a density higher than 1 Kg/dm3 constituted by a chamber connected with a feed duct (1 ) and a discharge duct (2) and a liquid pushing means that slides in said chamber having a ring profile (7). The pump is constituted by a wheel (4) activated by a power system (3) and by a stator (6), the wheel (4) brings in rotation the liquid pushing means (5) having the same dimensions of the transversal section of the ring profile chamber (7), both slots of the feed duct (1 ) and of the discharge duct (2) ' are realized on the external surface of the stator (6), that between the slot of the discharge duct (2) and the slot of the feed duct (1 ) is located a shutter (8) that can be operated by a system that reads the angular position (9) of the liquid pushing means (5).
