The hydraulic power unit of the NG-SHM Class DP – Servo Hydraulic Testing Machine offers several operational and structural benefits due to its dual-pressure design. It consists of two distinct sections: a high-pressure part operating at 25MPa for the main cylinder and a super high-pressure part operating up to 50MPa for the clamping cylinder. This separation allows the system to apply the right amount of pressure for each specific function, enhancing accuracy and safety during tests.

The main cylinder, which handles core mechanical testing tasks, functions at approximately 25MPa, delivering steady and reliable force. Meanwhile, the clamping cylinder uses about 48MPa, making sure that test specimens are held securely. Both pressure systems are efficiently managed by a single motor that powers the oil pump, simplifying the design and lowering energy usage. This integrated approach minimizes mechanical complexity, reduces operational noise, and supports longer system life with fewer components requiring maintenance or replacement.
