Citric Acid Chemical Industrial Pumps and Its Applications
Citric acid is an organic acid with the chemical formula C6H8O7. It exists naturally in great amounts in a variety of fruits and vegetable, most notably the citrus fruit family, including lemons, limes and grapefruits. In 2007, worldwide citric acid production amounted to a staggering 1.6 million tons. More than 70 percent of this volume is used in the food industry.

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 Common Citric Acid Uses?
- Food Industry: Citric acid can be found in many soft drinks and foods. It acts effectively as an organic preservative. It also adds the pleasant bite of the citrus flavor that makes many soft drinks so great. Citric acid is also widely used in ice creams as an emulsifying agent to prevent fats from separating.
- Cleaning Agent: Citric acid is a perfect chelating agent. It is also widely used to remove limescale from evaporators and boilers. Citric acid is useful in laundry detergents and soaps, helping to soften the water. In industry, citric acid is used to dissolve rust from steel.
- Cosmetics, Pharmaceuticals and Personal Care Products: Citric acid is widely used as an acidulant in gels, creams and liquids of all kinds. It is also used in shampoos to lower the pH level so hair becomes shinier and smoother. By acting as an antioxidant and stimulating collagen production, citric acid can also help improve the health of skin cells.
What Kind of Pump Can Handle Citric Acid?
It is recommended to choose a centrifugal sealless magnetic drive pump for handling citric acid at room temperature. Polypropylene, Kynar plastic and stainless steel have a high degree of resistance when coming in contact with citric acid and are generally good choices when selecting a citric acid chemical pumps.
Depending on concentration and temperature, citric acid can become heavy. For cases where the specific gravity is more than 1.1, decoupling or overloading the motor is possible. To prevent that, a trimmed impeller is absolutely necessary.
Choosing the Right Citric Acid Pump
Here at March Pumps, we offer a wide range of chemical pumps that are specifically designed to handle citric acid. These pumps cover the whole range from 5 GPM to 200 GPM. But the type of pump you choose greatly depends on the acid temperature, the concentration of the acid in use, its special gravity and many other factors that should be studied before choosing a pump.
