Abstract: The pump has an integrated fluid pressure actuator which provides for the movement and the axial retention of a movable cover which closes one end of the seat of rotation of the lobes of the pump itself. When the pump is in operation, the movable cover closes the seat of the lobes whereas, when the pump is to be washed, the cover is moved away from the lobes to allow effective circulation of the cleaning liquid. The pump is further equipped with a circuit for washing the seals on the shafts, which is automatically active when the movable cover is in the retracted position of the washing phase and which, in this state, draws the cleaning liquid directly from the suction pipe of the pump, makes it circulate behind the seals on the shafts and discharges it into the delivery zone of the pump itself. The pump is also equipped with apertures which perform the function of indicators of malfunctioning of the pump itself in the event of the main seals on the shafts giving way.
