Abstract (en)
[origin: EP0527227A1] A vertical pump (1) having spiral blades (10, 11 and 12) fixed to the distal end of the main shaft (2) thereof. One or more spiral blades (10, 11 and 12) are arranged to be well-balanced with respect to said main shaft (2) of the pump, whereby a flow passage between spiral blades is wide, of no-closure type, and thus makes the pump particularly appropriate to sewage disposal. <IMAGE>
