The hydraulic spear model tube puller is used to remove tubes from heat exchangers before re-tubing without damaging the tube sheet holes.
The spear is screwed into the relevant tube by means of an impact wrench or slow running nutrunner motor
The hydraulic cylinder with collar and quick action chuck is placed over the puller mandrel. The jaws are then closed around the thread on the puller mandrel by manual operation.
The tube is now ready to be removed by actuating the hydraulic ram.
