The Jingjiang FP-Z polypropylene self-priming/centrifugal anti-corrosion pump is a versatile chemical process pump that combines self-priming and centrifugal capabilities, specifically designed for transporting corrosive media.
I. Materials and Corrosion Resistance
Integrated Molded Reinforced Polypropylene (CFR-PP)
The pump body, impeller, and other flow-through components are injection molded from high-quality polypropylene material, offering high mechanical strength and withstanding temperatures ranging from -40℃ to 80℃. It exhibits excellent resistance to corrosive media such as acids, alkalis, and salts (e.g., sulfuric acid, hydrochloric acid, sodium hydroxide), making it suitable for industries including chemical processing, electroplating, and environmental protection.
II. Self-priming Function and Structural Design
High-efficiency self-priming mechanism
The pump chamber has a built-in suction chamber, a storage chamber, a gas-liquid separation chamber, and a return hole. After the initial filling, no repeated priming is required. The self-priming height can reach 4-5 meters, and suction can be resumed within 12 minutes of liquid interruption.
Scientific Flow Channel Design
Utilizing Danish technology to optimize the hydraulic model, the impeller and pump casing flow channels are smooth, reducing resistance and increasing efficiency by more than 15%.
Leak-proof structure
The WB2 mechanical seal requires no external cooling water and is equipped with a submersible valve to prevent backflow, achieving leak-free operation.
III. Performance Parameters and Applicable Scope
Flow Rate and Head
Flow rate range 4-100 m³/h, head 11-32 m, speed 2900 r/min, meeting the requirements of medium flow rate and high head.
Multi-scenario adaptability
Suitable for fields such as chemical and pharmaceutical industries (corrosive liquids), wastewater treatment (including particulate media), and food processing (hygienic conveying).
IV. Operation and Maintenance Advantages
Convenient Installation
Compact design, lightweight, inlet and outlet flanges conform to standards, pipe installation requires independent support to prevent deformation.
Low maintenance costs
The bearing shells are made of hard alloy and feature a WB2 leak-proof mechanical seal, supporting quick disassembly and maintenance.
Safety Protection
Dry running and reverse rotation are prohibited. A filter must be installed when conveying media containing particles. A high-power motor is required when the specific gravity is >1.2.
V. Upgrades Compared to Traditional Pump Models
Replaces Submersible Pumps
Eliminates the need for immersion in the medium, preventing shaft seal corrosion and reducing maintenance frequency.
Energy-Efficient and Eco-Friendly
Features a Y2-series motor paired with high-precision bearings; offers low noise levels and reduces energy consumption by 10% compared to traditional pumps.
Through structural innovation and material optimization, this pump resolves critical issues such as seal failure and low efficiency during the transfer of corrosive media, making it an ideal choice for upgrading chemical processing systems.
