Eccentric spiral pump for pumping has intermediate shaft with at least two offset webs with intermediate wall between them

摘要

The eccentric spiral pump has a drive connected to a rotor-stator unit by an intermediate shaft (10) connected directly to both of them. which much reduced cross section. The intermediate shaft has at least two webs (20, 22) offset from each other, running perpendicular to the longitudinal axis of the intermediate shaft, with an intermediate wall (24, 26) between the webs.
