After a run-in with the domestic market and inspection manual pump, high pressure hand pump fully meet the current market demand, working pressure of 100 ~ 300Mpa; equipped with pressure relief valve to prevent pressure overload, the pump is also a safety relief valve; Texas Lu of the secondary flow design force hand pump, a low pressure level displacement of 33CC, when two high-voltage displacement 1.6CC; realized under conditions of constant power, low voltage and high oil flow, high pressure low flow supply savings time and improve efficiency. External dimensions of 585 * 120 * 170mm, with oil on the total weight of about 11Kg SSS-B-type manual pump flow from the valve type high and low pressure complex quantitative piston pumps, check valves, relief valves, valve, fuel tanks and other components Shandong Dezhou hand pumps, manual mechanical energy is converted to pressure of the liquid to a small hydraulic pump station. SSS-B-type manual pump flow from the valve type high and low pressure complex quantitative piston pumps, check valves, relief valves, valve, fuel tanks and other components, is capable of a manual of mechanical energy into fluid pressure small The pump station. It has a high pressure, versatility, small size, light weight, compact, easy to operate, especially for field no power workplaces.
