Chemical Pumps for Potassium Hydroxide

Potassium hydroxide, chemically written as KOH, is a chemical compound that is used in the production of many familiar products. Potassium hydroxide is known to be beneficial to the production and manufacturing of materials like soaps, and fuels, for example, making its presence ubiquitous in business and industry.

With such industrial settings using potassium hydroxide, chemical pumps built to accommodate this chemical are often necessary. March Pump carries diverse chemical pumps equipped and designed to handle potassium hydroxide. March Pumps’ TE-5.5C-MD and AC-3CP-MD pumps are examples of those that work well for pumping potassium hydroxide. March Pump offers many, many more pumps capable of responding to this challenge.

March Manufacturing has a long history of responding to chemical and business challenges with chemical pumps. As such, March Pumps’ experts can guide clients toward the perfect pump for their needs, resolving their chemical pumping issues and helping their industrial and business production flourish.

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

What are Some Applications of Potassium Hydroxide in the Industry? 

Potassium hydroxide has similar characteristics to sodium hydroxide and is used in similar industries, but for different applications, mainly due to its costs and degree of solubility in water. Industrial uses and applications include: 

• Precursor to other potassium compounds: Potassium hydroxide is mainly used as a precursor to creating potassium salt compounds including those of cyanide, carbonate, phosphate and permanganate. Potassium phosphate is prominently used in fertilizers. 
• Manufacturing of biodiesel: Potassium hydroxide, although more expensive than utilizing sodium hydroxide, operates well in the production of biodiesel from vegetable oil. 
• Manufacturing of soft soaps: The so-called potassium soaps are softer than the more widespread sodium hydroxide derived soaps. Potassium soaps require less water and therefore can contain more cleaning material and thus are preferred for the creation of soft soaps. 
• Manufacturing of alkaline batteries: Since potassium solution is more conductive than sodium hydroxide, it is preferred as an electrolyte in the production of alkaline batteries. 
• As a caustic treatment in refineries: Potassium Hydroxide reacts with organic acids and sulfur compounds to improve the smell and color of petroleum. 
• Production of detergents, pharmaceuticals, and food – Potassium hydroxide is valued for its white crystals in the manufacture of soap. In food, it is invaluable as a stabilizer and thickening agent, as well as for adjusting pH.  

Pumping Considerations for Potassium Hydroxide 

Potassium hydroxide is an inorganic base with strong alkaline properties that can be damaging to human tissue and the respiratory tract. It can also damage your pump due to its corrosive nature.  

Below are important considerations when pumping potassium hydroxide: 

• Potassium hydroxide’s varying specific gravity and freezing point – Potassium hydroxide’s fairly high freezing point makes it susceptible to freezing especially if the pump is positioned in an exposed area with the chemical fluid sitting inside it for a long period. 
• Type of pump – Only leak-free pumps should be used to transfer the chemical. Mag drive pumps or double diaphragm pumps are highly recommended for pumping caustic solutions as they do not allow leakages.  
• Piping – Potassium hydroxide reacts with aluminum, copper, brass, and bronze based alloys and can cause dangerous leakages of hydrogen gas. These materials should be avoided in your piping system. 

What are the Properties of Potassium Hydroxide that will Affect Your Chemical Pump Choice?

Potassium hydroxide has many similar characteristics to sodium hydroxide. They are both highly caustic and corrosive and require special workforce and equipment considerations to handle the compounds. The specific gravity of potassium hydroxide depends greatly on its concentration; while 1 at a 1 percent concentration, it increases to 1.5 at a 50 percent concentration. Potassium hydroxide has also a relatively high freezing point and if the fluid sits in the pump for longer periods, it may freeze. On the other hand, increasing the potassium hydroxide’s temperature will have an exponential effect on its corrosive nature.

As with most chemical fluids, leak free pumping solutions, like mag drive pumps, are recommended.

What Pumps can Manage Potassium Hydroxide and at What Temperature and Viscosity?

March Pumps has a wide range of industrial pumps specially designed to handle Potassium Hydroxide. These pumps range from 5 GPM to larger capacities of 200 GPM for virtually any need.

Depending on temperature and concentration, potassium hydroxide can be heavy. If the special gravity is more than 1.1, it is absolutely necessary to use a trimmed impeller to avoid decoupling or overloading the motor.

For pumping potassium hydroxide at room temperature, a sealless magnetic drive pump built with polypropylene or Ryton plastic with the appropriate Teflon O-ring and suitable Carbon/Ryton combination bushing is recommended.

Finding the Right Potassium Hydroxide 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.
