March Chemical Pumps For Sodium Hypochlorite

_{A single or collection of material/s may be rated for a higher temperature/s then the pump as a whole is capable of. It is important to contact a March representative to determine if the pump as a complete unit is suitable for the concentration and temperature of any chemical.}

What are some applications of Sodium Hypochlorite in the Industry? 

Different concentrations of Sodium Hypochlorite are used for many purposes. 

• Bleaching: The use of sodium hypochlorite to bleach paper can be traced back to early in the 19th century. Since then, multistage bleaching processes have developed whereby industries use sodium hypochlorite as an invaluable process fluid when bleaching fabrics, papers, and leathers. It is also added to industrial wastewater to reduce odors. Concentrations of 3 to 8 percent of Sodium Hypochlorite are also widely used for bleaching in households. 
• Stain Removal: Due to Sodium Hypochlorite’s excellent destaining properties, it is widely used to remove dental stains and stains on dishes and cups, especially tea stains to name a few. The compound is also used in some washing powder brands. 
• Disinfection: Healthcare facilities use Sodium Hypochlorite in different areas and forms because of its broad spectrum of antimicrobial activity. The food industry also uses weak solutions of the compound for the same purpose. 
• Deodorizing: Sodium Hypochlorite exhibits very good deodorizing properties which make it an even better solution for disinfection and stain removal. 
• Water Treatment: Most water treatment facilities in Europe and the US use Sodium Hypochlorite for water treatment because of its excellent disinfection properties and low cost. 
• Medical treatment – When diluted, sodium hypochlorite is an important antiseptic used for minor wound care or before surgical procedures to prevent infections caused by cuts or abrasions. It can also be used to treat skin conditions such as eczema.  

Pumping Considerations for Sodium Hypochlorite 

Sodium Hypochlorite is an oxidizer capable of corroding human tissue as well as metals. Proper handling is therefore paramount when using the chemical in its concentrated form. 

• Avoid most metals in the selected pump specification – instead, consider using pumps that incorporate non-metallic materials like polypropylene or PTFE in their wet-side. 
• Sodium hypochlorite dosing – a tube pump, metering pump, or peristaltic hose can be used to deliver a predetermined quantity of chemical that doesn’t damage your pump and pipe installations.  
• Type of pump – in the transfer of larger quantities of sodium hypochlorite, centrifugal mag drive pumps give better results for chemical containment.  
• Venting – the design of your venting at the point of discharge can protect or damage your pump depending on how efficiently it releases trapped vapor. 
• Maintenance – regular flushing is recommended to prevent scaling which blocks pipework, especially in hard water areas.  

What are the properties of Sodium Hypochlorite that will affect what pump and material you purchase? 

Sodium Hypochlorite is a strong oxidizer with a high PH value. Liquids with concentrations of 500 ppm of chlorine or more are highly corrosive and will damage metals and other inner parts of the pump over time. Therefore, industrial pumps need to use resistant materials for parts that come into contact with the compound. 

What pumps can manage Sodium Hypochlorite and at what temperature and viscosity? 

March Pumps has a wide range of industrial pumps specially designed to handle Sodium Hypochlorite. These pumps include smaller ones with 5 GPM and heavy ones with up to 200 GPM capacity that cover virtually any need. These pumps are designed to handle Sodium Hypochlorite viscosities at room temperature. 

Finding the right Sodium Hypochlorite pump 

There are many parameters which should be taken into account when choosing the suitable pump for a particular use case. These parameters include but are not limited to compound concentration, working temperatures, gravity of the chemical and the materials used in the pump itself. 

Here at March Pump, we exhibit a wide range of chemical industrial pumps that cover virtually any possible requirement. For further info, we encourage you to contact our friendly support team and our experts will be happy to help. You can give us a call or contact us online.
