March Chemical Pumps For Sodium Hydroxide

Choosing a Sodium Hydroxide Industrial Pump

Sodium Hydroxide, commonly known as lye or caustic soda, is an inorganic compound with a strong metallic base. Caustic soda is available in a number of forms including granules, pellets, flakes, and solutions prepared with different concentrations. The chemical Sodium Hydroxide can also be heavy depending on the concentration and temperature.  If the specific gravity is more than 1.1, a trimmed impeller is absolutely necessary to prevent decoupling or overloading the motor.

Higher concentrations and higher temperatures of the chemical Sodium Hydroxide, together or by themselves, may make the pumps listed above unsuitable.  It is highly recommended, regardless of the temperature or concentration, that you contact a local distributor or March Manufacturing direct to review your application before ordering a pump. Sodium Hydroxide is widely used in a colorful spectrum of industrial and chemical processes and as of 2004, had a worldwide demand of over 51 million tonnes.

Chemical Pumps for Sodium Hydroxide

Sodium hydroxide, chemically written as NaOH, is a chemical used in the manufacturing of myriad products and across industries. Sodium hydroxide can be used to develop cleaning solutions and in material development.

Sodium hydroxide is toxic, and like many other chemicals it must be handled cautiously. It can be dangerous if it comes into contact with unprotected skin, for example.

March Pump offers extensive pumps for sodium hydroxide and has a team of experts that can help clients find the perfect pump for their precise challenges in business and industry alike. March Pumps built to accommodate sodium hydroxide include the TE-6T-MD in addition to the TE-7.5P-MD and the 320-CP-MD, among many others. Each one of these pumps offer different specifications and a variety of maximum flow rates and maximum heads.

Considering the complexity of sodium hydroxide and the wide-range of industries to which it is applied, March Pump encourages clients to leverage the knowledge of their team of experts before placing an order. Handling such chemicals within specific business and industrial context requires particular chemical pumps, and March Pumps’ experts can help guide clients toward the perfect pump for a given situation and application.

Disclaimer: These are only some of the pumps that can handle these chemicals.

What industries and applications handle Sodium Hydroxide (Caustic)?

Sodium Hydroxide is widely used as a strong base to dissolve in water and combine with an acid to create a salt. It has many use cases for PH regulation and the manufacturing process of different sodium salts.

In broader terms, it is used in many scenarios where the goal is to increase the alkalinity of a combination to neutralize an acid.

Some of the specific use cases of Sodium Hydroxide include:

• Paper industry: One of the key steps in the process of creating paper out of wood is chemical pulping. This step, and other steps involved in the process of making paper require strong alkaline environments of above 10.5 PH.
• Food industry: The food industry widely uses Sodium Hydroxide for chemical peeling or washing of vegetables and fruits. Cocoa beans are also processed with caustic soda. Some methods for softening olives also involve sodium hydroxide.
• Cleaning agent: Sodium Hydroxide can easily remove fats, oils, grease and protein based compounds and therefore, is used widely as an industrial cleaning agent where it is commonly known as “caustic”. One of the typical methods of using sodium hydroxide is to heat it as a solution and then spray it with high pressure. Sodium hydroxide in the form of a thick liquid gel or dry crystal is also used in homes as a drain opener.

What are the properties of Sodium Hydroxide (Caustic) that will affect what pump and material you purchase?

Caustic soda is a highly corrosive compound and is extremely reactive with some metals and alloys including aluminum and carbon steel.

Leak-free pumping is a particular concern when dealing with high concentration sodium hydroxide solutions. Caustic soda leaks not only cause severe injuries to personnel but can also damage the best equipment. To avoid that, a pump without mechanical seals, such as a mag drive model, is recommended.

What materials can best handle Sodium Hydroxide (Caustic)?

In normal cases where the concentration of sodium hydroxide is not very high most metals as well as polypropylene, PTFE, PVDF and EPDM can be used. In cases where caustic soda with very high concentrations are involved special synthetic materials and special alloys are required.

Finding the right Sodium Hydroxide Chemical 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.
