Abstract

A pumping unit comprises: a first pump (6), having a respective first drive shaft (6a) and able to be associated with a tank (2) containing a first liquid and with at least one delivery pipe (E) for conveying a quantity of said first liquid from the tank (2) to said delivery pipe (E); a second pump (7), having a respective second drive shaft (7a) and able to be associated with the tank (2) and with a source (S) of a second liquid for supplying a quantity of said second liquid to the tank (2), one of said pumps (6, 7) being connected to motor means for receiving a driving power; means (8) for transmission of the movement, active between said first drive shaft (6a) and second drive shaft (7a) so as to transmit a driving power between the two pumps (6, 7). The transmission means (8) comprise an epicyclic gearing (9), which is connected to both the drive shafts (6a, 7a) so as to cause rotation of said drive shafts (6a, 7a) at different relative speeds, and said first drive shaft (6a) and second drive shaft (7a) are coaxial and rotatable about a same main axis of rotation (X).
