Pump Type And Material Selection For Conveying Sodium Hypochl
TIME：2024-07-27 Author：admin Views：
Sodium hypochlorite (NaClO) is a commonly used disinfectant and is widely used in water treatment, sewage treatment, swimming pool treatment and other fields. However, due to its corrosiveness, it is crucial to choose the right pump type and material. This article will discuss the pump type and material selection for conveying sodium hypochlorite.
Pump type
Centrifugal pump: Centrifugal pump is a commonly used pump type for conveying liquids, suitable for conveying low-concentration sodium hypochlorite solutions. It has the advantages of simple structure and stable operation, and is suitable for applications with small flow and low pressure.
Magnetic pump: The magnetic pump adopts a design without mechanical seals, drives the liquid flow through magnetic transmission, and is suitable for conveying high-concentration sodium hypochlorite solutions. The magnetic pump has the advantages of no leakage and easy maintenance, and can effectively prevent sodium hypochlorite leakage and volatilization.
Material selection
Polypropylene (PP): Polypropylene is a commonly used plastic material with good corrosion resistance and chemical stability, suitable for conveying low-concentration sodium hypochlorite solutions.
Polyethylene (PE): Polyethylene has good corrosion resistance and wear resistance, and is suitable for conveying low-concentration sodium hypochlorite solutions.
Fluoroplastic (such as polytetrafluoroethylene, PTFE): Fluoroplastic has excellent chemical stability and corrosion resistance, and can withstand high-concentration sodium hypochlorite solutions. It is a commonly used pump material choice.
Stainless steel (316L): Stainless steel has good corrosion resistance and high temperature resistance, and is suitable for conveying low-concentration sodium hypochlorite solutions.
In summary, choosing the right type and material of sodium hypochlorite delivery pump is the key to ensuring safe and effective sodium hypochlorite delivery. In actual selection, it is necessary to consider the working parameters such as sodium hypochlorite concentration, temperature, flow rate, etc., and combine the characteristics of different pump types and materials to conduct comprehensive evaluation and selection to ensure that the pump is stable and reliable during use and achieve the expected delivery effect.
