1. Double plunger design, low pressure output large flow, high pressure output small flow, the highest pressure output can reach 4000bar (400Mpa), even when the highest working pressure is reached, only a small handle force is required.
2. The hand pump has a built-in double pressure safety valve to prevent pressure overload.
3. The built-in energy storage mechanism of the hand pump ensures stable pressure.
4. The specially designed fuel tank cover can realize the sealing of the fuel tank to prevent leakage or ventilation to balance the air pressure inside and outside the fuel tank.
