- Reusable packer intended for use in both pre- and post-grouting applications. Used for sealing boreholes at the tunnel face, in forepoling, excavation pits, and similar applications. Should be mounted with Pretec’s injection pipe and can be used with both Pretec low-pressure and high-pressure injection pipes. The Pretec reusable packer (PMU) has the same rubber length as the PSU packer but lacks a check valve and locking rings. This allows a fully expanded packer to be released and removed from the borehole by loosening the tightening nut, allowing the rubber to return to its original shape. The recommended torque to be applied to the tightening nut is 80–100 Nm to ensure proper anchoring in the borehole and to prevent grout leakage between the borehole wall and the packer.
