Electric hydraulic test pumps are used for hydrostatic tests of various pressure containers, pipelines, valves and steam boilers, etc. and for the obtainment of high-pressure liquid in the laboratory. At 5°C-60°C, the press medium is water or neutral oil whose viscosity is similar to water.

　　He pump of this kind is capable of pressing and boosting pressure quickly to shorten the testing time at the initial stage. After the pressure has exceeded 2mpa (downward adjustment available), the flow will be reduced automatically for the smooth and slow process. The pump, so to speak, has two kinds of flow at high and low pressures, capable of automatic switching. In case it falls within the rated discharge pressure, a hydrostatic test at any pressure can be conducted.
