Schematic Diagram:

Technical Parameters:
- Weight: Approximately 140 kg for the unit without oil
- Ambient temperature: -20℃ ~ +55℃
- Nitrogen charging working pressure: 10–60 MPa
- Setting range of digital pressure controller: 6–60 MPa (factory preset at 30 MPa)
- Oil tank capacity: 30 L
- Working medium: Conventional 46# anti-wear hydraulic oil
- Low-pressure gas inlet: ZG1/4 internal thread, fitted with high-pressure hose for connection to nitrogen cylinder
- High-pressure gas outlet: ZG1/4 internal thread, connect to nitrogen charging tool and then to the accumulator to be charged. (Nitrogen charging tool is configurable upon customer request.)

Schematic Diagram:

Technical Parameters:
- Drive gas pressure: 0.3–0.8 MPa
- Inlet pressure: 4–10 MPa
- Output pressure: 4–40 MPa
- Maximum flow rate: 50 L/min at standard condition (when drive gas pressure is 0.8 MPa)
- Drive gas inlet: φ12 PU tube quick push-in fitting
- Low-pressure gas inlet: ZG1/4 internal thread, fitted with high-pressure hose for connection to nitrogen cylinder
- High-pressure gas outlet: ZG1/4 internal thread, connect to nitrogen charging tool and then to accumulator to be charged. (Nitrogen charging tool is optional according to customer requirements.)
Equipment Features:
- When the set pressure is reached, the booster pump stops automatically with no additional energy consumption.
- The booster pump will start automatically to replenish pressure if the pressure drops below the set value.
- No power supply required (suitable for explosion-proof applications).
