Sigma 51P3 Pump Suction Cup, 150 mm with Gauge

Sigma 51P3 pump suction cup with a gauge.
One of the best pump suction cups, and one of the dearest. It will do for every type of tile, rough included, and for glass as well. It holds vertical and horizontal loads. It has a metal cylinder that takes heavy loads. The piston has a metal rod, so it puts up with being pumped by fist and the like. The vacuum is shown and checked by the pressure gauge, and also by the red line on the handle. If it appears, pump it up again. There is no guard against pressing the air release valve. These cups are also used in Sigma tile carrying frames, because they have proved themselves. For example, two cups suit tile 1200 x 1200 mm. One cup is for tile up to 600 x 1200 mm. You have to be careful, because tile with micro-cracks, or with a structure where the layers meet in the form of micro-cracks, will not hold on any simple vacuum cup at all, and there you have to look at pump cups. One more thing – the tile you are carrying has to be clean.
