Pumps for the Phosphate Fertilizer Industry

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.

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

Dilute Acid Transfer

Handling Media

Application:

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:

  • UHB Series UHMWPE Corrosion-Resistant Pump — for corrosive acid containing fine particles or solids
  • CYF Series Fluoroplastic Centrifugal Pump — for corrosive acid transfer where a fluoroplastic-lined clear-liquid pump is appropriate
  • CYQ Series Magnetic Drive Chemical Pump — for applications where leakage control is a primary consideration

Selection Considerations:

  • Acid concentration
  • Operating temperature
  • Solid content
  • Required flow and head
  • Leakage requirements

Mother Liquor Circulation

Handling Media:

Application:

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:

  • UHB Series UHMWPE Corrosion-Resistant Pump — for mother liquor containing suspended or abrasive particles
  • CYF Series Fluoroplastic Centrifugal Pump — for relatively clear corrosive process liquor
  • CYQ Series Magnetic Drive Chemical Pump — where a sealless configuration is preferred for corrosive process liquids

Selection Considerations:

  • Solids concentration and particle size

Fluorosilicic Acid Transfer

Handling Media:

Application:

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:

  • CYF Series Fluoroplastic Centrifugal Pump — 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
  • Temperature
  • Suspended solids
  • Required flow and head
  • Leakage requirements

UHB Series UHMWPE Corrosion Resistant Pump

UHB Series Corrosion Resistant Pumps deliver stable chemical transfer for acid, alkali, and slurry applications in chemical, new energy, metallurgy, pharmaceutical, and environmental industries.

Phosphoric Acid Slurry Transfer

Handling Media:

Application:

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:

  • UHB Series Horizontal Chemical Slurry Pump

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
  • Flow rate
  • Pump head
  • Wear characteristics

UHB Series chemical slurry pump features UHMW-PE lining and semi-open impeller, designed for corrosive, abrasive slurry transfer in chemical, metallurgy, fertilizer, and wastewater industries.

Fluorosilicic Acid Containing Silica Gel

Handling Media:

Application:

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:

  • UHB Series UHMWPE Corrosion-Resistant Pump
  • UHB Series Horizontal Chemical Slurry Pump

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.

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.

The 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.
