Ultrahigh-pressure hand pump is made of ultra-high-strength lightweight alloy with high safety and ultra-light weight design, which is about 50% lighter than the conventional model and is lightweight and easy to carry. Therefore, the mobility and convenience of the ultra-high pressure hand pump is very obvious. Let Xiaobian explain the characteristics of ultra-high pressure hand pump what? What are the characteristics of high pressure hand pump? 1, double plunger design, low pressure output large flow, high pressure output small flow, the maximum pressure output up to 4000bar (400Mpa), even when the maximum working pressure is also very small Handle force. 2, hand pump built-in dual pressure relief valve to prevent pressure overload. 3, hand pump built-in energy storage institutions to ensure that the pressure is stable. 4, specially designed fuel tank cap, tank seal can be achieved to prevent leakage or breathe to balance the pressure inside and outside the tank. When the pump head down to work in the vertical state.
