Choosing a Phosphoric Acid Industrial Pump
Phosphoric acid is a colorless, clear and odorless liquid. It is a strong inorganic acid with the chemical formula H3PO4. It can be produced by absorbing phosphorous pentoxide directly in water or through the digestion of phosphate rock with sulfuric acid. The most common form of phosphoric acid is an 85 percent aqueous solution. Phosphoric acid has a wide range of uses, including as a food additive, rust inhibitor, fertilizers, electrolyte, dispersing agent, dental and orthopedic etchant and many more. The chemical Phosphoric Acid 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 Phosphoric Acid, 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.

Chemical Pumps for Phosphoric Acid
Phosphoric acid, chemically written as H3PO4, is a chemical compound known for its application to etching and use in foods and textiles. This chemical has diverse applications and as such, depending on the situation to which it is going to be applied, the right chemical pump is necessary.
March Manufacturing has been providing a wide-range of accommodating chemical pumps to clients for over fifty years. As such, March Pump has a team of experts when it comes to chemical pumps and finding the perfect pump for a given situation. Clients from countless industries need chemical pumps for pumping phosphoric acid.
March Pump is happy to offer pumps like that of the BC-2CP-MD Magnetic Drive Pump with a maximum flow of 5 gallons per minute at 13 feet, which is a centrifugal magnetic drive pump that includes Polypropylene in its construction. The TE-5C-MD 1 Phase Magnetic Drive Pump is another great example of a pump designed to handle phosphoric acid, and with a maximum flow of 18 gallons per minute.
March’s experts can help clients find the perfect pump for their business or industrial setting. March Pump encourages clients to leverage the industry-knowledge that clients maintain to find the perfect pump for their needs before making an order.
Disclaimer: These are only some of the pumps that can handle these chemicals.
What Are Some Industry Applications of Phosphoric Acid?
- Agriculture: About 90 percent of phosphoric acid production is used to produce fertilizers. To produce phosphate salts, the phosphoric acid is reacted with the minerals available in phosphate rock.
- Food Industry: Popular for its sharp, tangy taste, food-grade phosphoric acid created through the thermal creation process is used to acidify beverage and foods. For instance, the acidity of most sodas is created through the use of phosphoric acid.
- Rust Removal: For rust treatment, phosphoric acid solutions are created as a gel or dipping bath to be applied to rusted areas.
- Medical Industry: Phosphoric acid is used in an assortment of teeth whiteners for removing plaque. It is also widely used as an etching solution in orthodontics and dentistry to roughen and clean surfaces of teeth before fillings or dental appliances are placed.
Pumping Considerations for Phosphoric Acid
Phosphoric acid is highly corrosive and capable of damaging the skin and eyes when handled at 85% concentration. Precautions should therefore be taken when dealing with this chemical. Some of the considerations to keep in mind include:
- Sealless pumps –Using o-ring assembly as opposed to regular seals reduces abrasive wear when the fluid comes into contact with the pump. Mag drive pumps are good examples of sealless pumps which minimize the risk of leakage.
- Pump casing material – Casing material should only use specific metals that have a long working life. Hastelloy – a corrosion-resistant nickel alloy is ideal for pumping phosphoric acid even in its concentrated form.
What Properties of Phosphoric Acid Will Affect the Pump Material Selected?
The specific gravity of phosphoric acid ranges from 1.3 to 1.95 depending on the concentration. At a concentration of 85 percent, which happens to be an industry standard, phosphoric acid tends to be very corrosive and extremely damaging to skin and eyes. Since the S.G. can vary greatly, it is paramount to plan ahead and consider this in the pump you’ll use.

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 Materials Handle Phosphoric Acid the Best?
While some metals may have short working lives, they can be used in phosphoric acid pumps. Stainless steel, for instance, suffers a high rate of corrosion when coming in contact with phosphoric acid, but some grades are usable, although they suffer from a short working life. For better chemical resistance a non-metallic build, using materials such as polypropylene and kynar, are recommended. Viton, PTFE and Kalrez elastomers are very resistant to phosphoric acid corrosion, but for higher concentrations, natural rubber should be avoided.
Finding the Right Phosphoric Acid Chemical Pump
March Pumps offers a wide range of chemical pumps that cover virtually any industry and special use case. The type of the pump you choose greatly depends on the concentration of the acid you plan to use, the acid temperature, its special gravity along with a host of other factors.
