Elliptical suction cup Ventose

flatroundrectangular

Overview
Comprehensive VUOTOTECNICA® catalogue of vacuum cups and accessories for gripping, handling and clamping a wide variety of materials and shapes. Product families cover cup-shaped, flat, bellows, elliptical, rectangular, foam and special suction cups, plus supports, adapters and accessories for industrial applications (packaging, glass, automotive, tiles, electronics, food and general industry).

Key features

• Many geometries: cup, flat, bellows, reinforced bellows, double/multi-bellow, star (SV series), Maxigrip, circular rim, rectangular/elliptical, labyrinth-faced and custom profiles.
• Compounds: standard (N = natural para rubber, A = oil-resistant, S = silicone) and special (BENZ, GERANIUM OF foam, NF neoprene foam, EPDM SB) for temperature/chemical needs.
• Supports & fittings: nickel-plated brass, anodised aluminium, galvanised steel, Anticorodal; male/female threaded pins, M8 calibrated holes, side vacuum ports, AQ flanges, adapters (GAS↔NPT, metric↔GAS) and non-rotating holders.
• Typical uses: handling glass, marble, ceramics, sheet metal, painted panels, packaging (flow-pack), films, bottles, cans, food items, textured tiles and delicate substrates (Bernoulli non-contact handling).

Selected product families

• Vacuum cups with supports: traditional cup shapes in a wide diameter range, cold-fittable on nickel-plated brass or anodised aluminium supports with threaded pins for quick replacement.
• Vulcanised support cups: cup vulcanised to metal support for heavy-duty / stamped-sheet handling; BENZ compound available for high oil/chlorine resistance.
• Star Vacuum (SV series): star-reinforced contact area for handling flat and flexible objects without deformation; available with male/female metal fixings.
• MAXIGRIP cups: for robotics/automotive; flat or bellows, round or oval; BENZ compound option for wide temperature and oil/water resistance.
• Packaging & thin-film cups: very thin lips and internal cleats to distribute vacuum and avoid deformation of films and bags; recommended natural para compound for best adhesion on plastics/paper.
• Foam rubber cups (GERANIUM, NF): high-density or open-cell foam versions for very rough/uneven surfaces; self-adhesive sheets/strips for custom attachment.
• Vacupredator: cups for bags and flexible containers with slotted plate and foam seal to accommodate creases; designed for high reliable grip at typical vacuum levels.
• VMG134 for structured tiles: high-density foam cup with Anticorodal support, dual vacuum connections and self-adhesive side for textured/raised tile surfaces.
• Bellows & multi-bellow cups: adapt to irregular surfaces, compensate flatness errors and enable picking single sheets in packaging/food lines.
• Flat, labyrinth-faced & circular-rim cups: for heavy loads, thin fragile sheets and parts with central holes (discs, pulleys); choice of compound by application.
• Bernoulli vacuum cups: non-contact handling using compressed air for very delicate or lightweight substrates (wafers, solar cells, foils).
• Accessories: wide range of adapters, threaded reductions, AQ square flanges for robotics, filters, O-ring seals and calibrated grub screws to tune suction area.
