The Battioni Pagani pulley is a pneumatic clutch assembly with dimensional characteristics and performance particularly suitable for controlling the engagement and disengagement of vacuum pumps, blowers, high-pressure piston water pumps, and centrifuges, installed above the vehicle frame, where the pump and/or blower operation occurs via a belt drive.

The use of clutches on combined vehicles for the emptying of septic tanks and channel washing allows for the engagement and disengagement of vacuum and water pumps without having to stop the rotation of the drive that powers the input pulley, thus ensuring the operator extreme ease of use of the setup and a reduction in passive times.
