Described herein is a pump for digging equipment for the construction of diaphragms, in which: the equipment envisages in its end part drums (10 and 11), provided with bits (12) mounted so that they rotate on their own axes (A); and the drums are carried by a top frame (13), mounted within which, in the proximity of the drums, is a centrifugal pump (14). The pump (14) is positioned in such a way that its axis (15) comes to lie in a substantially horizontal plane, parallel to the plane passing through the axes (A) of the bits (12) and is oriented at an angle of between 30° and 60° with respect to the sides of the rectangular section of the excavation, whilst the maximum diameter of the pump and its motor fall within the thickness of the frame (13).
