        • Suction cups

          • How do I know which lifting forces I need?
            • It depends on the weight of the product that should be lifted and how many suction cups that can be used for the object. Calculate the weight to be lifted per suction cup and then take the weight multiplied with the gravity force (g=9.81) and you have the lifting force needed in Newton (N)

          • How do I know which suction cup to choose?
            • Our recommendation is to start at the application listing to find the products we recommend to different applications. If you have questions please do not hesitate to contact our partners to find the optimum solution.

          • How should Piab suction cups be stored?
          • I have a variation of number of objects to be lifted- how can I make sure to not drop them or to use too much energy? How to optimize this type of system?
            • All suction cups not in contact with an object (open) will draw in a lot of air and demand a larger pump than actually necessary. By using different valves, such as piSAVE sense, in the suction cups, the suction cups will be normally closed until they come in contact with the handled object. Only the cups needed in the specific lifting cycle will be open and flow air. Please see the video piSAVE sense.
