The 4DSY-I series pressure testing pump produced by our company is an ideal equipment for obtaining high-pressure liquids in various pressure vessels, pipelines, boilers, steel cylinders, valves, pressure vessels, and fire-fighting equipment for laboratory and hydrostatic testing. The pressure testing pump products and supporting pressure testing and testing engineering have been applied in pressure testing in the aviation field and in key development projects for national defense research. Made significant contributions to major scientific research projects in China, such as high-pressure blasting tests, deep-sea tests, space technology, high-temperature and high-pressure tests, and special-shaped pipe tests.

This pump system is specially designed according to the requirements of hydrostatic testing. In the initial stage of pressure testing, it has a large flow rate and can quickly fill and increase the pressure to shorten the experimental time. When the pressure exceeds 1.6 MPa, in order to ensure a smooth and slow pressure testing process. The traffic will automatically decrease. So this pump has two flow rates at high and low pressures, and can automatically change. Any hydraulic pressure test can be conducted below the rated discharge pressure.
