Because of its reactive and corrosive character, handling sodium hypochlorite presents several complications. To overcome these issues, specialized equipment such as Sodium Hypochlorite Pumps are utilized. March Pumps understands this requirement and has designed a line of Sodium Hypochlorite Pumps specifically for sodium hypochlorite, assuring smooth operations without sacrificing safety or efficiency.
Sodium hypochlorite is a chemical that is widely utilized in a range of sectors, particularly for disinfection, bleaching, and water treatment. Its versatility and efficacy make it an essential component in maintaining public health standards and industrial processes.
Sodium hypochlorite is mostly produced by the electrolysis of sodium hydroxide and chlorine. Because of the safety issues connected with shipping and handling chlorine in its elemental form, sodium hypochlorite is produced on-site wherever possible.
Sodium hypochlorite is an unstable compound that degrades into sodium chloride. The shelf life of a concentrated solution ranges from 28 to 90 days, depending on the storage conditions. Sodium hydroxide is added to home cleansers containing sodium hypochlorite to slow down the breakdown process.
Sodium hypochlorite is exceedingly corrosive and poisonous to both human flesh and metals. Sodium hypochlorite is an extensively used chemical due to its oxidizing, antibacterial, and bleaching properties on materials such as textiles.
Applications of Sodium Hypochlorite Pumps

Sodium Hypochlorite Pumps have a wide range of applications in many industries. Some of the key applications are:
Water Treatment Plants
Water Treatment Plants use Sodium Hypochlorite Pumps to disinfect drinking water and treat wastewater. Accurate dosing is essential to ensure that the water is free of pathogens and safe for consumption or disposal.
Swimming Pools
Sodium hypochlorite is frequently used to disinfect pool water, making it safer for swimmers. Sodium Hypochlorite Pumps built for this use guarantee that the proper amount of chemicals is delivered to keep chlorine levels consistent and prevent the growth of hazardous germs.
Food and Beverage Industry
The food and beverage industry employs sodium hypochlorite to clean and disinfect equipment, surfaces, and water sources. In this case, Sodium Hypochlorite Pumps must be capable of delivering precise amounts of chemicals to ensure complete disinfection while ensuring food safety.
Hospitals and Healthcare Institutes
Hospitals and healthcare institutes use sodium hypochlorite for disinfection. Sodium Hypochlorite Pumps disinfect surfaces, equipment, and water supplies, reducing the likelihood of healthcare-associated infections.
Textile and Paper Industries
The textile and paper industries use sodium hypochlorite as a bleaching agent. Sodium Hypochlorite Pumps deliver the chemical to bleaching processes, ensuring consistent and uniform bleaching results.
Chemical Manufacturing
Chemical manufacturing uses sodium hypochlorite as a raw material or intermediate. Sodium Hypochlorite Pumps are used to deliver and dose the chemical accurately, ensuring the efficiency and safety of production activities.
Cooling Towers in Industrial Facilities
Cooling towers in industrial facilities use sodium hypochlorite to inhibit microbial growth and biofilm development. Sodium Hypochlorite Pumps ensure that the correct amount of chemicals is delivered to the cooling water, hence maintaining system efficiency and preventing contamination.
Agriculture
Sodium hypochlorite is used to disinfect irrigation systems and water sources. Sodium Hypochlorite Pumps ensure that the chemical is accurately dosed, hence preserving crops and guaranteeing safe irrigation procedures.
Pumping considerations

Sodium hypochlorite requires careful material selection. This is due to the chemical’s strong oxidizing capabilities. It is typically recommended that most metals be avoided in pump specifications.
Metals like aluminium, cast iron, and stainless steel corrode, while higher-end alloys like titanium, Hastelloy, or duplex may be acceptable depending on the concentration. Avoid using elastomers like Acetal, Buna, nylon, and polyurethane.
It is recommended to use a non-metallic structure constructed of polypropylene or PTFE, with wet-side materials such as PTFE, ceramic, Hypalon, EPDM, ETFE, PVC, or Viton.
At wastewater treatment plants, the chemical may be dosed via a peristaltic hose tube pump or a metering pump with diaphragms that deliver a chemical quantity determined by a probe sensor such as turbidity or pH.
These pumps’ positive displacement enables them to provide the necessary priming suction for extraction from a tank/IBC at low flow rates while also being easily regulated for consistent delivery.
Because of its operating principle, the peristaltic pump can handle gaseous fluids, making it ideal for hypochlorite solution, which often ‘gasses off’ and creates vapour locks in traditional pumps.
To prevent vapour locks, systems and pumps are usually designed with venting at the output and highest point. Pump heads may have auxiliary attachments such as a manual or automated bleed valve to release trapped gas.
Scaling can also occur in pipelines, particularly in hard water areas, and can occasionally cause the line to halt. Regular flushing is recommended.
