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
نقل الحمض المخفف
الوسائط المعالجة
Dilute phosphoric acid / Dilute sulfuric acid / Acidic process liquids
التطبيق:
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.
المضخات الموصى بها:
- مضخة UHB سلسلة UHMWPE UHMWPE المقاومة للتآكل — for corrosive acid containing fine particles or solids
- سلسلة CYF مضخة الطرد المركزي الفلوروبلاستيكية CYF — for corrosive acid transfer where a fluoroplastic-lined clear-liquid pump is appropriate
- مضخة كيميائية ذات محرك مغناطيسي من سلسلة CYQ — for applications where leakage control is a primary consideration
Selection Considerations:
- Acid concentration
- درجة حرارة التشغيل
- المحتوى الصلب
- Required flow and head
- متطلبات التسرب

Mother Liquor Circulation
الوسائط المعالجة:
Acidic mother liquor / Process liquor / Liquids containing suspended solids
التطبيق:
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.
المضخات الموصى بها:
- مضخة UHB سلسلة UHMWPE UHMWPE المقاومة للتآكل — for mother liquor containing suspended or abrasive particles
- سلسلة CYF مضخة الطرد المركزي الفلوروبلاستيكية CYF — for relatively clear corrosive process liquor
- مضخة كيميائية ذات محرك مغناطيسي من سلسلة CYQ — where a sealless configuration is preferred for corrosive process liquids
Selection Considerations:
- Solids concentration and particle size
- Acid concentration
- درجة الحرارة
- Continuous circulation duty
- Leakage control requirements

Fluorosilicic Acid Transfer
الوسائط المعالجة:
Fluorosilicic acid / Fluoride-containing acidic liquids
التطبيق:
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.
المضخات الموصى بها:
- سلسلة CYF مضخة الطرد المركزي الفلوروبلاستيكية 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
- درجة الحرارة
- المواد الصلبة العالقة
- Required flow and head
- متطلبات التسرب

Phosphoric Acid Slurry Transfer
الوسائط المعالجة:
Phosphoric acid slurry / Acidic slurry containing solid particles / Gypsum-containing slurry
التطبيق:
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.
المضخات الموصى بها:
- سلسلة UHB مضخة الملاط الكيميائي الأفقية 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
- معدل التدفق
- رأس المضخة
- Wear characteristics

Fluorosilicic Acid Containing Silica Gel
الوسائط المعالجة:
Fluorosilicic acid containing silica gel / Suspended silica-containing acidic liquid
التطبيق:
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.
المضخات الموصى بها:
- مضخة UHB سلسلة UHMWPE UHMWPE المقاومة للتآكل
- سلسلة UHB مضخة الملاط الكيميائي الأفقية 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?
تشانجيو 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.
