VACUUM BELL is a plastic bell from Leister to check and ensure that overlap welding seams and application seams are leak-proof. This device is particularly used in landfill and tunnel construction. The vacuum required for the leak test is ideally generated with the VACUUM PUMP by Leister. Weld seam errors are reliably detected with the VACUUM BELL. Particularly during tunnel and landfill engineering, irregularities in a weld seam must be avoided to exclude lack of quality and prevent damage later on.
Together with the VACUUM PUMP from Leister, the necessary vacuum pressure is easily generated.
The Leister vacuum bell and pump are available for short and long-term hire from Polyweld Machinery.
