Phosphoric Acid Production

Phosphoric acid is produced by reacting phosphate rock with sulfuric acid, generating a slurry that includes gypsum and other by-products. The resulting mixture is highly abrasive, corrosive, and dense, requiring robust slurry-handling systems for filtration, clarification, and transfer.

Challenges:
The acid-rock reaction creates a highly erosive and low-pH slurry that destroys conventional pumps rapidly. Scaling, crystallization, and solids buildup further contribute to clogging and wear. Pump failures in these circuits lead to contamination, high maintenance costs, and process interruptions.

Solution:
Hevvy/Toyo pumps are engineered to thrive in aggressive phosphoric acid environments. Their high-chrome or rubber-lined wet ends resist abrasion, while acid-resistant materials prevent corrosion. Recessed impeller and agitator options keep gypsum solids in suspension, minimizing blockages and ensuring smooth, continuous operation in both production and recovery circuits.
