How to choose a self priming pump for media containing Cl⁻

For chlorine containing wastewater, the material selection of the pump is very important because chloride ions can cause corrosion to the pump material. The following are some pump materials suitable for chlorine containing wastewater:

Stainless steel self suction pump: Stainless steel is a corrosion-resistant material suitable for chlorine containing wastewater. Among them, 304 and 316 stainless steel are the most commonly used materials. 304 stainless steel is suitable for general concentration chloride ion environments, while 316 stainless steel is more suitable for high concentration chloride ion environments. However, it should be noted that the corrosion resistance of stainless steel is influenced by factors such as temperature, concentration, and flow rate.

Fluorine plastic self suction pump: Fluorine plastic is an excellent corrosion-resistant material that can withstand the erosion of high concentrations of chloride ions and strong acids and alkalis. Therefore, fluoroplastic pumps are suitable for the treatment of chlorine containing wastewater.

Hastelloy self-priming pump: Hastelloy is also a corrosion-resistant material, especially suitable for high concentration chloride ion environments. However, the price of HC/HB alloy is relatively high, so comprehensive consideration is needed when choosing.

When selecting the material of a chlorine containing wastewater treatment pump, it is necessary to comprehensively consider the specific situation of the wastewater, including factors such as chloride ion concentration, temperature, flow rate, etc. In addition, factors such as pump performance and economic benefits need to be considered to select the most suitable pump material. It is recommended to consult a professional engineer or supplier when selecting a pump to obtain more detailed and accurate advice.
