Diverters and Pneumatic Take-offs, Venturis

Diverters e Venturi pneumatic grippers are fundamental components in pneumatic conveying systems for bulk and powdery materials, used for the controlled management, distribution, and feeding of material flows within industrial plants.

Diverters are used to direct material to different transport lines, silos, or process sections, allowing for flexible and controlled management of paths within the plant. Their operation requires high precision, continuous operation, and reliability, especially when handling abrasive materials and high transport speeds.

Venturi pneumatic grippers, on the other hand, operate by exploiting the Venturi effect, using pressure variations generated by airflow to create a vacuum capable of sucking and conveying material within the pneumatic line. These systems are used in the material pickup and feeding stages from hoppers, containers, or collection points to subsequent transport and processing sections.

Both systems operate under conditions characterized by high flow velocities, turbulence, and the presence of highly abrasive materials, factors that generate intense erosion and wear phenomena on internal components.

The areas most subject to deterioration are, in particular:

• internal surfaces of the switchgear
• flow direction change points
• Interception and material distribution equipment
• nozzles and Venturi tubes
• suction and feed lines
• pneumatic fittings, bends, and connections
• Surfaces subject to severe erosion from continuous material impact

In these contexts, SARO intervenes with anti-wear solutions designed to increase component operating life, improve the reliability and efficiency of pneumatic transport systems, and reduce maintenance interventions.

SARO develops anti-wear solutions through:

• high abrasion resistance ceramic coatings – SARCER & SARMOS
• wear-resistant technical components - SARCER
• SAROMAX100 Components and Coatings – SAROMAX CURVE & PIPES
• integrated solutions designed for high-speed environments subject to mechanical stress

Solutions are designed considering:

• Type of material transported
• abrasiveness and grit
• transport speed and pressure
• Pneumatic flow dynamics
• Line configuration and diversion points
• Operating conditions and continuity of operation

SARO supports complex industrial plants in the design and optimization of pneumatic transport systems, developing anti-wear solutions tailored to actual operating conditions and specific process needs.
