Abstract (en)
[origin: US2006104840A1] The invention concerns a dual pump, comprising an electric motor ( 18 ) including a drive shaft, the shaft including, at each of its axial ends, a shaft output ( 21, 22 ), and two pump impellers, each shaft output driving a respective pump impeller, one first of the pump impellers ( 23 ) operating at low pressure and high flow rate, and the second of the pump impellers ( 30 ) operating at higher pressure and lower flow rate. The water pumped by the second pump impeller ( 30 ) is drawn proximate the outlet of the first pump impeller ( 23 ) and returns to the inlet of the second pump impeller. The drawing point is situated in a low pressure pump chamber, upstream of the low pressure outlet ( 16 ). The invention is applicable to swimming pool maintenance.
