ZI DOUBLE INFLATABLE PACKERS BIMBAR ( 28-170MM)

Available dimensions: Ø 28, Ø30, Ø42, Ø56, Ø170

Each single packer from Ø 28mm to Ø 170mm can easily be transformed into a double packer assembly by adding a specific element: the central element CE. Just unscrew the sliding end from the single packer and replace it with the CE element. Complete the installation by screwing a standard inflatable element S (sleeve) and a plug PL on the lower part of the packer.

The perforated CE central element from Ø 56mm to Ø 170mm consists of a compact and perforated tube, with a diameter identical to the whole packer assembly. This design makes the double packer ZI extremely robust and the external flush O.D. is particularly well adapted to micropiles grouting and water pressure tests.

With Ø 28,30 and 42mm packers, the narrow space between the two packer elements does not allow to use the same tubular design.

Here, the CE element consists of 4 pipes, two of which are used for inflation of the lower packer.

As standard, the central element can be extended except the 42mm one which is on request only.

A special characteristic of these packers is that the injection zone (IZ) length remains constant after inflation.
