Pompes pour l'industrie des engrais phosphatés

Phosphate fertilizer production involves dilute acid, mother liquor, fluorosilicic acid, and phosphoric acid slurry. The pumping conditions vary from one process to another. Acidic liquids can attack conventional wetted materials, while slurry containing solid particles can cause wear inside the pump.

Changyu’s UHB Series corrosion-resistant pump is designed for these types of liquid and slurry transfer duties. Its wetted parts use ultra-high-molecular-weight polyethylene (UHMWPE), a material known for its resistance to chemical corrosion and abrasive wear. The low friction coefficient of UHMWPE also helps reduce material adhesion inside the flow passage when handling certain process media.

Below, we look at the phosphate fertilizer production process, the characteristics of its main process media, and how the UHB Series is selected for different pumping duties.

Fluide applicable

Phosphate Fertilizer Pumping Applications

Phosphate fertilizer production involves different process liquids and slurries. The pump selection changes with the medium, solids content, temperature, flow requirements and leakage requirements. Changyu matches the pump type and wetted material to each process duty rather than using one pump design for every application.

Changyu provides customized pump solutions for phosphate fertilizer production, covering:
Dilute acid transfer / Mother liquor circulation / Fluorosilicic acid transfer / Silica-containing acid transfer / Phosphoric acid slurry transfer

Acide sulfurique dilué

Handling Media

Dilute phosphoric acid / Dilute sulfuric acid / Acidic process liquids

Utilisation :

Dilute acid is transferred between reaction, storage and process equipment during phosphate fertilizer production. The main requirement is resistance to the acid concentration and operating temperature, while the required flow and head determine the hydraulic configuration.

For dilute acid containing suspended particles, a slurry-capable pump is more appropriate than a conventional clear-liquid centrifugal pump.

Recommended Pumps:

  • Série UHB Pompe résistante à la corrosion en UHMWPE — for corrosive acid containing fine particles or solids
  • Pompe centrifuge en plastique fluoré de la série CYF — for corrosive acid transfer where a fluoroplastic-lined clear-liquid pump is appropriate
  • Pompe chimique à entraînement magnétique de la série CYQ — for applications where leakage control is a primary consideration

Selection Considerations:

  • Acid concentration
  • Température de fonctionnement
  • Contenu solide
  • Required flow and head
  • Exigences d'étanchéité

Mother Liquor Circulation

Handling Media:

Acidic mother liquor / Process liquor / Liquids containing suspended solids

Utilisation :

Mother liquor circulation can involve acidic liquids containing dissolved salts and suspended particles. The pump therefore needs to handle both the chemical environment and, depending on the process, abrasive solids.

Recommended Pumps:

  • Série UHB Pompe résistante à la corrosion en UHMWPE — for mother liquor containing suspended or abrasive particles
  • Pompe centrifuge en plastique fluoré de la série CYF — for relatively clear corrosive process liquor
  • Pompe chimique à entraînement magnétique de la série CYQ — where a sealless configuration is preferred for corrosive process liquids

Selection Considerations:

  • Solids concentration and particle size
  • Acid concentration
  • Température
  • Continuous circulation duty
  • Leakage control requirements

Fluorosilicic Acid Transfer

Handling Media:

Fluorosilicic acid / Fluoride-containing acidic liquids

Utilisation :

Fluorosilicic acid requires careful material selection because the pump wetted parts are directly exposed to the chemical medium. For relatively clean liquid transfer, a fluoroplastic-lined pump can be considered. Where suspended solids or process residues are present, the pump configuration should also account for wear.

Recommended Pumps:

  • Pompe centrifuge en plastique fluoré de la série CYF — for corrosive fluorosilicic acid transfer
  • CYQ Series Fluoroplastic-Lined Magnetic Drive Pump — where leakage prevention is important
  • UHB Series UHMWPE Pump — where the medium contains suspended particles and wear resistance is required

Selection Considerations:

  • Fluorosilicic acid concentration
  • Température
  • Matières en suspension
  • Required flow and head
  • Exigences d'étanchéité

Série UHB Pompe résistante à la corrosion en UHMWPE

Les pompes résistantes à la corrosion de la série UHB assurent un transfert chimique stable pour les applications acides, alcalines et les boues dans les secteurs de la chimie, des énergies nouvelles, de la métallurgie, de la pharmacie et de l'environnement.

Phosphoric Acid Slurry Transfer

Handling Media:

Phosphoric acid slurry / Acidic slurry containing solid particles / Gypsum-containing slurry

Utilisation :

Phosphoric acid slurry combines chemical corrosion with mechanical wear. Suspended solids can wear the impeller and flow passage, while the acidic liquid places additional demands on wetted materials.

For this application, corrosion resistance alone is not enough. The pump also needs a flow passage that can handle solid particles without frequent blockage.

Recommended Pumps:

  • Pompe à boues chimiques horizontale de la série UHB

The UHB Series uses a steel-lined UHMWPE construction and a semi-open impeller. The semi-open impeller provides a larger flow passage for particle-containing slurry, while the UHMWPE wetted components resist both corrosion and abrasive wear. Changyu lists the UHB Series specifically for phosphoric acid slurry and phosphate fertilizer applications.

Selection Considerations:

  • Slurry concentration
  • Particle size
  • Liquid temperature
  • Débit
  • Tête de pompe
  • Wear characteristics

La pompe à boues chimiques de la série UHB est dotée d'un revêtement en UHMW-PE et d'une roue semi-ouverte. Elle est conçue pour le transfert de boues corrosives et abrasives dans les secteurs de la chimie, de la métallurgie, des engrais et des eaux usées.

Fluorosilicic Acid Containing Silica Gel

Handling Media:

Fluorosilicic acid containing silica gel / Suspended silica-containing acidic liquid

Utilisation :

When fluorosilicic acid contains silica gel or other suspended solids, the pumping condition changes from a relatively clean chemical transfer duty to a combined corrosion and wear application.

The pump needs to provide chemical resistance while allowing the suspended material to pass through the flow passage without excessive accumulation or blockage.

Recommended Pumps:

  • Série UHB Pompe résistante à la corrosion en UHMWPE
  • Pompe à boues chimiques horizontale de la série UHB

Why UHB?

The UHB Series combines a UHMWPE-lined flow passage with a semi-open impeller. This configuration is intended for corrosive liquids containing particles and is particularly relevant when the process medium combines chemical corrosion with abrasive wear.

Why Choose Changyu for Phosphate Fertilizer Pumping?

Changyu provides pump solutions for dilute acid transfer, mother liquor circulation, fluorosilicic acid transfer, silica-containing acid transfer, and phosphoric acid slurry handling in phosphate fertilizer production. Depending on the medium and operating conditions, our engineers can recommend UHB, CYF, CYQ, or other suitable pump configurations rather than using the same pump for every application.

For corrosive liquids and particle-containing slurry, material selection is particularly important. The UHB Series uses UHMWPE wetted parts for applications where chemical resistance and abrasion resistance are both required, while other pump types can be selected for relatively clear corrosive liquids or applications with specific leakage-control requirements.

From medium composition and concentration to temperature, solids content, flow rate, and head, Changyu evaluates the actual process conditions before recommending a pump. Contact Changyu to discuss your phosphate fertilizer pumping application and get a pump configuration based on your process requirements.

FAQ

There is no single pump type for every phosphate fertilizer application. Pump selection depends on the process medium, solids content, temperature, flow rate, head, and leakage requirements. Changyu may recommend UHB, CYF, CYQ, or another suitable pump according to the specific process conditions.

Phosphoric acid slurry contains suspended solids and is both corrosive and abrasive. The UHB Series is suitable for this type of application because its wetted parts use UHMWPE, which provides chemical resistance and high abrasion resistance. Slurry concentration, particle size, temperature, flow rate, and head should be considered during selection.

Yes. The UHB Series is designed for corrosive liquids and slurry containing suspended particles. Its UHMWPE wetted parts provide resistance to chemical corrosion and abrasive wear, making the series suitable for applications where both conditions occur.

The appropriate pump depends on the fluorosilicic acid concentration, temperature, solids content, flow rate, and leakage requirements. CYF or CYQ pumps can be considered for relatively clear corrosive liquids, while UHB can be considered when suspended particles or abrasive solids are present.

Mother liquor can contain acidic components, dissolved salts, and suspended particles, so the pump should be selected according to its actual composition and solids content. UHB is suitable when wear resistance is required, while CYF or CYQ may be considered for relatively clear corrosive mother liquor.

Provide the pump manufacturer with the medium name, chemical composition, concentration, temperature, flow rate, required head, solids concentration, particle size, and operating conditions. These parameters allow the pump type, wetted material, hydraulic configuration, and sealing arrangement to be evaluated for the specific application.

Le phosphate fertilizer industry covers the processing of phosphate rock and the production of phosphoric acid and phosphate-based fertilizers. Phosphoric acid is an important intermediate in the production of phosphate fertilizers such as monoammonium phosphate (MAP) and diammonium phosphate (DAP).

Wet-process phosphoric acid production involves several process streams with different chemical and physical characteristics. Depending on the production stage, pumps may be required to transfer dilute acid, circulate mother liquor, handle fluorosilicic acid, or transfer phosphoric acid slurry containing suspended solids.

These applications are not identical from a pump selection standpoint. Clear acidic liquids mainly require suitable chemical resistance, while particle-containing liquids introduce additional wear considerations. For this reason, pump selection should be based on the actual medium, concentration, temperature, solids content, flow rate, and head rather than the industry name alone.

For phosphate fertilizer plants, Changyu provides different pump options for these process conditions, including UHB corrosion-resistant slurry pumps, CYF fluoroplastic centrifugal pumps, and CYQ magnetic drive pumps, with the final configuration selected according to the specific application.
