Hi guys, what do you recommend for a suction pump which is able to hold a weight of 3kg on a glass wall?

Best that the pump is light but possess strong suction power.

If your suction pump could pull a perfect vacuum then you would need a suction cup with an area of 3cm to hold 3kg. With a cup of 30cm area (6cm diameter) you would only have to suck out 10% of the air. It is the cup size that matters (where have I heard that before?).

Mmm, we have the suction cups you mentioned. Right now we are worried about our pump because we are unsure what kind of pump to use. Brand? Model? I am a noob, sorry

TEOSUC,

Does the pump need to run continuous, or intermittently (minutes?...hours?...days?)
