Model ：4DY-720/12A-30/300A Series
1. Summary

Modle 4DY-720/12A-30/300A Series electric pressure testing pump ( here after called pump for short) is and equipment provided specially for testing water pressure of various pressure vessels, pipes ,valves, and etc., and for getting high pressure liquid in labs .This pump is specially designed in the light of the requirements of mater pressure test. During the initial stage of pressure testing, the pump can be quickly filled with liquid and its pressure booms thus shortening the testing time. The pump has a greater flow,when the pressure is over 1.6Mpa（this pressure can be lowered, the flow is automatically reduced in order that pressure testing can be carried out smoothly and slowly .Therefore at high pressure and low pressure the pump has two different flows, which can be automatically shifted .If  the outlet pressure of the pump is less than the rated one, the test of any water pressure can be carried out .
