For viscous, abrasive, corrosive liquids, even at high pressure.

The peristaltic pump is based on a principle which is the human body: the contraction and relaxing motion of the muscles in the digestive tract. In fact, inside the pump there is a high resistance operating hose that is completely compressed in a strategic section by two rollers on bearings offset by 180°. During the interval between the two rollers, the hose reacquires its original geometry, creating a vacuum that sucks and transports the fluid being treated.

The volume moved is proportional to the useful displacement and the speed of rotation. It is therefore simple to dose the desired product quantity in a fixed or variable way, depending on whether you opt for a fixed or variable speed configuration by means of reducer, variator or inverter.

CHARACTERISTICS AND ADVANTAGES

• Possibility of dry operation for an indefinite period of time.
• Atoxic lubricant for continuous operation without the need for external lubrication by means of silicon oil or grease.
• No contact of the product with any moving mechanical part.
• Absence of seals and valves.
• Accuracy of the dosage throughout the entire life of the hose.
• Self-priming in extreme conditions (9.5 m of max vacuum).
• Treatment of heterogeneous fluids, abrasive fluids, fluids containing solids.
• Treatment of fragile fluids, viscous fluids, fluids containing gas, without emulsions, alterations or damage.
• Reversible flow for convenient cleaning and emptying of the lines and reservoir.
• Easy, economic and quick to service with extremely reduced machine down times.
• Hose: the only part subject to ordinary wear with a max replacement time of 30 minutes.
• Reducers with high service factors and drives with wide safety margins.
• Extremely flexible use with vast fields of application.
• Wide range of accessories.

For viscous, corrosive and food liquids at low pressure.

Patented self-priming peristaltic and reversible pump made in plastic material with rotor shaft coupled to unified gear reduction unit and electric motor. In order to achieve variable dose flow rates, the pump can be equipped with a mechanical variator, force-ventilated motor and separate inverter or an integrated motor and inverter.
The big advantage of this pump is that, compared with other volumetric pumps, it can operate dry without suffering any damage. Replacement of the operating hose, the only routine maintenance operation required, is simple and quick, causing maximum machine down time of 20 minutes.
Thanks to the rotor with 3 guide rollers and 3 pressing rollers, the pulsation of the flow rate, typical of these pumps, is significantly dampened. The operating hose allows food and chemical use for dosage of diluted acids and bases.

MATERIALS
Volute, rotating axis, pressing and guide rollers in high density Nylon, shaft in AISI 420, operating hose in FDA food compliant polypropylene-based thermoplastic elastomer. The pump has no mechanical seal systems.

APPLICATIONS
Transfer and dosage of viscous, acid or food fluids up to 80°C that do not contain abrasive particles. Maximum pressure 2.5 Bar and maximum flow rates over 20 m3/h.
