Valisi N Series
Medium-pressure peristaltic volumetric pump. Two rollers on a rotor compress a thick-walled tube alternately against a patented profiled guide, and, through rotation, propel the contents of the tube (the pumped liquid) from the suction line to the discharge line. This action creates a vacuum in the suction line, resulting in continuous suction. In N2-N4 models, the rotor is supported by large ball bearings within the pump body, while in N5N-N7N types, it utilizes heavy-duty bearings in the flanged gearbox. The tube can be extruded or reinforced with nylon fibers. All pumps can be supplied as monoblock units, coupled with gearboxes, speed controllers, electric, pneumatic, or hydraulic motors


Valisi VPH Series
High-pressure peristaltic roller pump. Two opposing rollers are mounted on a rotor, which alternately compresses a reinforced rubber tube containing the fluid to be pumped. The return of the tube to its resting position creates a vacuum, causing the product to be drawn in and propelled forward by the subsequent roller. Particularly suitable for transferring impure liquids, dense and viscous mixtures, as well as abrasive and corrosive products. The rotor is supported by heavy-duty bearings in the gearbox. The pump operates with constant lubrication in a mixture of silicones/glycerin/glycols.


Valisi Custom Series T-F-RM
Low-pressure peristaltic volumetric pumps. Two opposing rollers, rotating, alternately compress a tube against the patented concentric guide. The return of the tube to its resting position creates a vacuum, causing the product to be drawn in and propelled forward by the next roller. Particularly suitable for transferring impure liquids, dense and viscous mixtures, as well as abrasive and corrosive products. The pump operates dry: the only lubrication is a thin layer of silicone on the pressure roller. The tube can be extruded or reinforced with nylon or spring steel fibers. All pumps can be supplied as monoblock units, coupled with gearboxes, speed controllers, electric, diesel, pneumatic, or hydraulic motors.
