Sodium Hypochlorite Chemical Industrial Pumps and Its Applications

Posted: 6/7/2016

Sodium Hypochlorite (NaOCI), or commonly known as bleach, is a chemical compound made of a sodium ion and a hypochlorite anion. It is a clear solution with a slightly yellowish color and a telltale odor of household bleach.

Pump Material recommendations for Sodium Hypochlorite Concentrations

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: Concentrations of 3 to 8 percent of Sodium Hypochlorite are 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.

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.

Choosing 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.
