Medium sized single screw pump, able to work in a versatile manner with whole, crushed, de-stemmed or fermented grapes up to 35 tons per hour. Designed to work optimally downstream of the Alfa 30 mod. de-stalker/crusher, in various reciprocal configurations, it also lends itself well to single operation, as a simple transfer unit. The rotor and stator are heavy duty, in order to ensure high performance at low rpm. The control panel allows careful and prompt control of all working parameters while the level sensors inside the hopper guarantee adequate protection against overflowing and running dry.
