Abstract

A system is described, in particular for cleaning, comprising: at least one high-pressure pumping unit (1) adapted to pump water or other similar fluids with a high output pressure; at least one electric motor (3) connected to the variable-pressure pump (1) for its actuation; at least one device (5) for regulating the revolutions of the pump (1), connected to the motor (3) for its control and for regulating the pump (1) in order to deliver water at a variable pressure, preferably from 0 to 500 bar, and at a very low flow-rate, preferably from 2 to 4 1/min; at least one nozzle (15) equipped with at least one rotary head rotated by at least one pneumatic motor; and at least one air compressor (7) designed to provide the supply compressed air to such pneumatic motor.
