Model K344 Packer

Model K344 packer is a hydraulic expansion packer set by differential pressure across the tubing, once the tubing pressure exceeds annulus pressure by 0.4-1.2MPa (58-174psi), the elements will expand to seal the annulus, it is often used with a chock unit to build up pressure for sealing during injection.

The packer is widely used for multiple zone water injections, acidizing, casing leak locating, and some fracturing applications. It contains no moving parts and has zero risk of getting stuck, which makes it an ideal choice for interventions.
