Peristaltic
Valisi - TF-RM
Peristaltic volumetric pumps for low pressures. Two opposed rollers, rotating, alternatively compress a tube against the patented concentric guide. The return of the tube to the rest position creates vacuum, causing the product to be sucked forward and pushed forward by the next roller. Particularly suitable for contaminated liquids, dense and viscous mixtures and abrasive and corrosive products. The pump runs dry: the only lubrication is a layer of silicone on the pressure roller. The tube can be extruded or reinforced in nylon fibers or harmonic steel. All pumps can be supplied in one-unit versions, coupled to gearboxes, regulators, electric, diesel, pneumatic or hydraulic motors.
- Max Flowrate: 2780 Lt/h
- Max Viscosity: 150.000
- Temp. Max: 100 °C
- Max Pressure: 2 bar
Valisi - N
Peristaltic volumetric pumps for medium pressures. The two alternating rollers on a rotor compress reciprocally a tube with thick walls in a guide with a patented shaped profile and, thanks to the rotation, push the content of the tube (the pumped liquid) from the suction line to the discharge line. Through the consequent opening of the tube, a vacuum is created in the suction line from which a continuous suction is going on. In the N2-N4 models, the rotor is supported by large ball bearings inside the pump body, while in the N5-N10 types it uses heavy-duty bearings for the flanged gearbox. The tube can be extruded or reinforced in nylon fibers or harmonic steel. All pumps can be supplied in one-unit versions, coupled to gearboxes, regulators, electric, diesel, pneumatic or hydraulic motors.
- Max Flowrate: 60.000 Lt/h
- Max Viscosity: 150.000
- Temp. Max: 100 °C
- Max Pressure: 7 bar
Valisi - FPSH
Peristaltic volumetric pumps for high pressures. The two opposed shoes are mounted on a rotor which alternately compress a reinforced rubber tube which contains the fluid to be pumped. The return of the tube to the rest position creates vacuum, causing the product to be sucked forward and pushed forward by the next shoe. Particularly suitable for contaminated liquids, dense and viscous mixtures and abrasive and corrosive products. The rotor is supported by bearings for heavy duty gearbox service. The pump works with constant lubrication of a mixture of silicones / glycerine / glycols.

- Max Viscosity: 1.000.000
- Temp. Max: 90 °C
- Max Pressure: 15 bar
