We select the bolt tensioning tool, pump, hose, manifold and gauge together for your application and supply them in one quotation, in the same pressure class and with matching connections. Rental, training and maintenance included.
The result of a bolt tensioning job does not depend on the tool alone: pump pressure and flow, hose pressure class, manifold outlets and gauge accuracy all work together. Sourcing components from different suppliers risks mismatched connections, the wrong pressure class and lost time. Hydro Bard configures the system as a whole for your application, manufactures the tools in its own CNC shop and completes them with pump, hose and measuring equipment in the same pressure class.
A complete set for torque-free, even preload on flange studs. Several tools run simultaneously from one pump through a manifold.
On large-diameter bolts the nut itself becomes the tensioning tool; a permanent mechanical lock holds the load.
Cylinder, pump and line selected together for lifting, pressing, pushing and assembly work.
Splitter, pump and hose together to remove seized nuts without damaging the bolt.
Configure it yourself: choose the application, enter size and quantity and get the tool, pump, manifold, hose and gauge list in one sheet.
Open the System Selector →Stud/bolt size and quantity, flange type, required preload or force, work location.
Tool model, pump type, hose quantity and length, manifold outlets, gauge.
All components in the same pressure class, with matching connections, in a single quotation.
System set-up and operator training.
Periodic maintenance, seal replacement and pressure testing.
Bolt tensioning tools (HRT or HCK), a 1500 bar hydraulic pump, 1500 bar high-pressure hoses, a manifold for multi-tool operation and a 1500 bar pressure gauge. The tool model and quantity depend on stud size, required preload and the number of studs tensioned at the same time.
No. When you share your application we select the tool, pump, hose, manifold and gauge with matching pressure class and connections and prepare a single quotation.
Manual (hand), air-driven and electric hydraulic pumps in the 700 bar and 1500 bar classes. The choice depends on the number of tools, the work location and the required speed.
No. Every component in a line must be rated for the highest working pressure. A 700 bar hose, valve or gauge must not be connected to a 1500 bar bolt tensioning or hydraulic nut system.
Yes. We offer hydraulic equipment rental. We also provide training and commissioning at delivery, and maintenance and pressure testing afterwards.
