Choose metering pump should pay attention to what aspects

The main metering pump selection should consider the following three levels: working pressure: When the metering pump is selected, its additional working pressure should exceed the required practical activities, which is generally higher than the operating scale in the middle of 10% to 20%, and it i

Why should metering pumps be equipped with safety valves

Safety valve in the machinery and equipment to ensure the effectiveness of reliable safety, if there is no safety valve, sometimes may cause explosion accidents. It can open and close autonomously according to the operating pressure, and optimize the safety maintenance system of the machine equipmen
