Abstract (en)
[origin: EP2740940A1] The pump (TP1) has a vertically spaced pump chamber facing an inlet opening, and a motorized rotating impeller arranged in the pump chamber. An adjustable unit (DR) is movable relative to a pump casing (PG) between a position for increasing an opening width of a passage aperture (DO) for a wastewater operation of the pump, and another position for reducing the opening width of the passage aperture for a clear water operation of the pump. The adjustable is moved between the two positions such that minimum suction height and/or maximum particle size are different for the two positions.
