Injection Pump

The injection pump is a device used in post-tensioning systems to inject cement-based grout into the duct surrounding the tendons under pressure. This process fills voids around the tendons, providing corrosion protection and creating a bond between the tendon and the concrete.

It is widely used in bridges, tunnels, dams, and other bonded post-tensioning applications, enhancing the durability and long-term performance of the system.
