The electric pressure test pump is a series of products that have been updated on the basis of the original 4DSB electric oil pump. It inherits the characteristics of the old type pressure test pump, such as high degree of "three changes" , long service life, stable performance and flexible movement, the structure of the transmission box and other parts has been changed. So that the series of products more reasonable parameters, more stable performance, more safe and convenient operation. The specifications of this product fully comply with JB/T9089-1099 pressure test pump. Electric Pressure Test Pump (hereinafter referred to as pump) is a professional for all kinds of pressure vessels, pipelines, valves, Steam Boilers and other pressure testing and laboratory to obtain high-pressure liquid equipment. This pump is specially designed according to the requirement of water pressure test. During the initial stage of pressure test, the pump can be filled and pressurized rapidly to shorten the test time and have a larger flow rate, in order to make the pressure test process can be more balanced, the flow automatically reduce, so this pump in high and low pressure with two flow, and can automatically change, where the rated discharge pressure, can be arbitrary pressure test.
