Product Description

Inflatable packers are widely used in fields such as hydropower stations, reservoir engineering curtains, consolidation, backfilling, chemical grouting, geological exploration water testing, drilling water plugging, etc. It is also used for coal seam plugging, water blocking, gas testing, and emission. Reusable.
The pure pressure grouting packer has two holes for water injection: the first hole is used to inject water or air into it, which is the expansion of the rubber hose; the second hole is used to inject cement.
The bottom hole circulating grouting packer has three holes for water injection: the first hole is used to inject water or air into it, causing the rubber hose to expand; The second hole is used for injecting cement; The third hole is used for draining water or water. Gas generated during the cement injection process.
