SINGLE HELICAL ROTOR PUMP

摘要

The subject of the invention is a single helical rotor pump, the helical rotor (8) of which is seated axially eccentrically in a couple with a statically and concentrically placed stator (7) and is coupled with the shaft (11) of the drive (1). The essence of the invention consists in the fact that the helical rotor (8) is partly embedded in a helical rotor joint (9) connected with the shaft (11) of the drive (1) and partly free mounted in the stator (7) which is hinged in the carrying casing (5) fixed between the suction casing (4) and the delivery branch (6) of the pump.
