I plant development and production of 3D-SY750 series of electrical pressure test pump can be used for all kinds of pressure vessels, boilers, pipes burst and all the pressure required for the test and strength test site, according to the value of the test pressure need to be locked, and can automatically protect pressure. The transfer medium pump is generally room temperature water, can also use the emulsion, rust and water viscosity similar to water and neutral oil. Coupled with cleaning attachments, the machine can also be used as a washing machine. China is currently the existing two-cylinder, four-cylinder electrical pressure test pump replacement. The product is small, compact, stable, safe, reliable, functional, flow, high efficiency and wide application and supporting strong, easy to operate.
