Inflatable borehole packers are essential tools in mining, geotechnical engineering and gas drainage. They seal boreholes quickly and reliably, enabling controlled grouting, water testing, permeability measurement and gas extraction in coal mines.

At Hebei Bangtian Mine Safety Equipment Co., Ltd., we manufacture a full range of inflatable packers from 30mm to 170mm OD, covering borehole diameters from 32mm to 330mm. Our packers are built with high-quality rubber elements, reinforced inner tubes and metal end fittings, with NPT or BSP threads to suit global standards.

Key applications include: coal mine gas drainage borehole sealing, grouting and reinforcement, hydraulic fracturing for coal seam water injection, groundwater monitoring, permeability and packer testing, and tunnel construction grouting.

Our FKSJ series packers are certified for coal mine safety (MA certification) and withstand working pressures up to 6 MPa. For applications requiring higher expansion ratios, our inflatable packers achieve free expansion diameters up to 350mm, making them suitable for large-diameter and irregular boreholes.

Replacement bladders are available for all sizes, allowing customers to extend the service life of their packers economically. As a factory-direct manufacturer with over 20 years of experience, we supply packers to mining companies, drilling contractors and equipment distributors in more than 20 countries.
