Pump such as hydraulic test pump is used to check for leaks in tube, pipe, boiler, cylinder, hose and other components through the use of high-pressure hydro testing. When the component to be tested is filled with water or oil, using a high-pressure pump with safety relief and control functions, the component is slowly brought up to a predetermined set point and held for a predetermined amount of time. The next step is to conduct a visual inspection to determine whether leaks are present or if the pressure is dropping. Pressure vessels and other equipment need hydrostatic pressure test pump or high pressure cement grout pump to ensure their safety and durability.
