Product Overview
At 700 bar — 10,000 psi — hydraulic power density reaches levels where a coffee-cup plunger produces tonnage, and where the system is only as safe as its weakest fitting, hose or gauge. Plunger (ram) cylinders dominate this class: the plunger itself is the pressure boundary, output force is simply pressure times plunger area, and design attention concentrates on plunger material, column stability at longer strokes, and the interfaces. The critical procurement truth of 700 bar systems is that nothing may be mixed casually: cylinder, pump, hoses, couplers and gauges must all carry matching pressure ratings, and assemblies must be pressure-tested as complete systems. Manufacturers listed here build single- and double-acting plunger cylinders to pressure-equipment-adjacent practice for pressing, straightening, bolt tensioning, proof-load testing and industrial/rescue tooling, with hydrostatic test certification per unit and compatibility documentation for the mating high-pressure components.
