How to choose a corrosion resistant pump

When designing the design equipment, the design institute should determine the purpose and performance parameters of the pump and select the pump type. This choice must first start with the type and form of the anti-corrosion chemical pump. So what are the principles for selecting a pump? What is the basis?
1. Make the type and performance of the selected anti-corrosion chemical pump meet the requirements of process parameters such as device flow, head, pressure, temperature, cavitation allowance, suction stroke, etc.
2. Must meet the requirements of media characteristics
For pumps that transport flammable, explosive, toxic or valuable media, shaft seals are required to be reliable or non-leakage pumps are used, such as magnetically driven pumps (no shaft seals, using indirect magnetic indirect drive)
For pumps that transport corrosive media, the convection parts are required to use corrosion-resistant materials, such as fluorine plastic corrosion-resistant pumps
For pumps containing solid particles, the convection parts should be made of wear-resistant materials. If necessary, the shaft seal should be rinsed with clean liquid.
3. Mechanical requirements require high reliability, low noise and small vibration.
4. Correctly calculate the input cost for the purchase of corrosion-resistant pumps.
