With our air-hydraulic pumps you can generate pressures up to 2500 bar. With the selected increasing ratio, the pump can be adjusted to the existing air pressure network. The air-hydraulic pumps are mainly used in explosion-proof areas. A pressure regulator installed at the input side can adjust the hydraulic pressure at the output side. The…

Automatic bolt tensioner
This purely axial method allows engaging the tensioning force exactly into the connection. The optimization of assembly time is the biggest benefit. Due to the automatic bolt tensioner eliminates time-consuming screwing and unscrewing. The resulting time saving of the tensioning is approximately 50%. Standard design Patented thread clamping Drive gear, teethed nut and gearbox Automatic…

Clamping stroke dependent version with spacer plate
The hydraulic nut consists essentially of an internally threaded cylinder, a piston and a splitted spacer plate. The hydraulic nut will be pressurized up to the desired pre-tensioning force. This creates a gap between the piston and cylinder corresponding to the elongation and compression of the components. In this calculated gap the corresponding spacer plate…
