Abstract

A vertical pump (1) having a single or plurality of helical blades (10, 11, 12) mounted on a forward end of a rotary drive shaft (2) of the pump. The pump is of non-blocked type in which the helical blade or blades (10, 11, 12) are disposed with superior balance with respect to the rotary drive shaft (2), and is wide in flow passage between blade portions of the helical blades. The pump is particularly suitable for sewage treatment or the like.
