Hydraulic diaphragm metering pump is a precise flow control pump that delivers liquid by driving a diaphragm through a hydraulic system. This type of pump is widely used in multiple industries, especially in situations where high-precision measurement and transportation of chemical agents, corrosive liquids, or high viscosity liquids are required. Here are some main application areas:

1. Chemical industry: used for accurately adding various chemical additives, acid-base solutions, etc.
2. Oil and gas industry: Used for precise control of chemical injection volume in processes such as oilfield water injection and polymer injection.
3. Pharmaceutical industry: Ensure accurate measurement of raw materials in the drug production process to ensure consistency in product quality.
4. Water treatment industry: used to add coagulants, disinfectants, etc. to sewage treatment systems to ensure treatment effectiveness.
5. Food industry: In some cases, it is used for the precise addition of ingredients in food processing, such as seasonings.
6. Environmental engineering: Used in wastewater treatment plants to add chemicals to regulate water quality.
7. Power industry: used in the desulfurization system of power plants to precisely control the supply of limestone slurry or other chemicals.
8. Paper industry: Used to add dyes, fillers, etc. in the paper production process.
