For extremely high temperature applications and or when handling food products.
SILICONE
Contact with food or FDA environments, packages, pre-colored plastic parts (high temperature), bakery (detectable), electronics/semiconductor (conductive/antistatic).
Bags with fragile contents and food, bags with liquids, viscous contents and frozen food (low temperatures), open bags.
NITRILE-PVC — Oil resistant, a traditionally designed cup.
CR — Especially good for low temperature environments, a traditionally designed cup.
NITRILE-PVCand CR
Conventional suction cup material for general purposes.
Used in handling hot parts or where silicone or PWIS is not allowed. Mark free.
HNBR
Removing hot plastic parts from injection moulding equipment, glass handling.
Suction Cup AccessoriesSuction cup accessories are parts which make it easier to position the cup, add level compensation, reduce the risk for damaging parts or give a precise movement to the cup.
Applications
Level Compensators /Spring plungers
Wide range of thread connections and stroke lengths.
Adjust differences in levels, for example on lifting devices with several suction cups.
Allows for soft placement of cups on sensitive or thin objects.
Available with rotational or non-rotational design (suitable for use with oval suction cups).
Height adjusterFacilitates installation. Provides a height extension between the
handling device and the suction cup. Adjustable in height.
Suction cup extensionsFor handling devices used in cramped areas.
Solid extension for mounting a suction cup.
Several heights available
Integrated filterFor increased system reliability in industrial environment
Available as an integrated filter disc in the bellow.
A mesh filter is also available in the fitting.
Ball jointsMounts on a suction cup to avoid stress
Non-leaking design to work with vacuum system for ergonomic assist arms or other devices with high degree of safety.
Available in loose-fit and locking versions.

piGRIP® – The first modular suction cup on the marketTaking gripping to new dimensions
Versatility and productivity
A modular suction cup that fits most machines and that can be optimized for handling almost all materials. piGRIP®’s six different lip types, optimized for various products to lift, ensure the right hardness/softness and sealing capability for your material. Combined with the firm bellows, piGRIP® is stable enough to handle faster accelerations and more high speed lifts as compared to traditional cups.
Your choices are endless, piGRIP® is available as a flat, one, three or as a six bellow cup. The availability of more than 40 different fittings, six different types of lips, and also a low micron filter disc for the bellow and a mesh filter for the fitting makes the variations of this modular suction cup endless. You can configure more than thousands and thousands of different types of cups to meet your exact need.
The green standard lip is suitable for relatively even surfaces on sealed materials. It has extra wear resistance.
The blue standard lip is recommended if the surface is more uneven or rough, e.g. textured plastic parts.
For surface leaking materials (wrinkled or textured) and porous materials, such as corrugated paper.
For difficult bags such as pouches and heavy bags with e.g. liquids.
Suitable when conventional lips are not sealing enough. Can replace mechanical grippers.
