High pressure hand pump coupled with equipment for different purposes, can be lifting, jacking, bending, pulling, cutting, manual pump pressure test, etc., suitable for field operation without power supply. Used in metallurgy, mining, railway, automobile, oil, electricity and other enterprises. High pressure hand pump built storage mechanism to ensure stable pressure, fuel tank cap seal acts like a safety valve to prevent tank overpressure; built-in dual pressure relief valve to prevent pressure overload. Relief check valve prevents the load within the free fall; dual piston design SBD20D hand pumps, two-speed feature reduces the number of pressure; manual pump control valve is easy to control manually uninstalled, the security decreased slowly; for there is no power and compression air site operations; EHV manual pumps specially designed tank cover, enabling the tank seal to prevent leakage or ventilation in order to balance the pressure inside and outside the tank. When the head down to work in a vertical state. Its high security, ultra-light weight design, light weight compared to conventional models about 50% of the low-pressure hand pump, light and easy to carry.
