Product Details
Self-priming + fluorine-lined anti-corrosion two-in-one composite structureIndependently developed composite industrial pumps combining the advantages of magnetic pumps and self-priming pumps. The pump body integrates a liquid suction chamber, liquid storage chamber, volute, return hole, and gas-liquid separation chamber. When starting, it automatically completes gas-water mixing and air separation. After pipeline emptying, vacuum is automatically rebuilt, eliminating the need for foot valves or manual pumping. At the same time, the fully fluorine-lined structure prevents leakage of strongly corrosive media, with performance comparable to imported high-end chemical pumps.
CFD simulates fluoroplastic hydraulic componentsThe pump body, impeller, and pump cover are all optimized through fluid mechanics simulation, using molded sintered fluoroplastic molding in one piece, featuring wide, smooth runners, high conveying efficiency, and excellent cavitation residual performance; Modular component design, interchangeable parts for models of the same caliber, reducing spare parts inventory costs.

The standard design pressure for the entire machine is 1.6MPa, with a suitable temperature range of -30°C to 120°C; Standard maximum self-priming height 3 meters; If the specific gravity of the conveyed medium exceeds 1.3g/cm³, advance notification is required when ordering. The factory customizes increased torque motor components; All models are optional with temperature monitoring devices, anti-slip protection devices, and online leak monitoring devices; All models listed in the table can be equipped with explosion-proof motors as needed.
PTFE/FEP fluoroplastic liners are suitable for temperatures of -30~120°C, capable of stably transporting any concentration of strong acids, strong alkalis, hydrofluoric acid, chromic acid, aqua regia, various organic solvents, and strong oxidizers. There are no prohibited scenarios for conventional strong corrosive media, making it a general anti-corrosion material for hazardous chemical transport. FEP material is not suitable for long-term high-temperature conditions above 120°C; high-temperature, highly corrosive chemicals require thickened PTFE linings for the entire machine. Silicon carbide bushings and sealing moving-stationary rings are adapted to corrosive chemicals containing trace soft crystals and fine solid particles, offering ultra-high hardness, wear resistance, and crystallization resistance, resulting in a longer service life; PTFE PTFE bearings are suitable for clean, particle-free, high-purity corrosive reagents, with no metal ion precipitation, making them suitable for transporting high-purity pharmaceutical agents; Fluororubber sealing gaskets are compatible with various acids, alkalis, and organic solvents, making them corrosion-resistant and aging-resistant, and suitable for a wide temperature range of working conditions.
Used for long-distance circulation and transport of strong acids, hydrofluoric acid, high-temperature reactive hazardous chemicals, and various organic solvents, with priority given to explosion-proof high-power models; The PTFE lining is highly resistant to highly corrosive media. With a self-priming height of 3 meters, it can directly extract chemical liquid from underground hazardous chemical storage tanks. The explosion-proof magnetic leak-proof structure eliminates the risk of volatilization of flammable and explosive media and static electricity fires, suitable for reactor circulation and hazardous chemical raw material tank transfer processes.
Transporting highly oxidizing and corrosive chemicals such as acidic etch, alkaline etch, plastic roughened hydrofluoric acid, and chromic acid, using DN25, DN32, DN40 small to medium flow specifications; Fully fluorine-lined material resists strong corrosion from chromic anhydride and hydrofluoric acid. The self-priming structure eliminates the need to immerse the pump in the chemical tank, and the entire machine is installed on the ground to simplify production line piping. When paired with a chromic acid filter, it is used as a set.
Transporting high-purity strong acid reagents, pharmaceutical extraction intermediates, and highly corrosive organic solvents, using DN25 and DN50 small-flow PTFE liner models; PTFE flow-through components have no metal ion precipitation, are fully sealed with no leakage or contamination, ensuring the purity of pharmaceutical raw materials and suitable for sterile solution preparation and extraction purification processes.

For transporting strong acid leachate smelting and rare earth extraction with high-density corrosive agents, select DN40, DN50, DN65 medium-flow high-lift models; The fluorine-lined material is resistant to strongly acidic media in mining and metallurgy, and the high-torque motor can be adapted to high-density slurry solutions, ensuring stable circulation of extraction agents.
Transporting high-purity, strong corrosive hazardous chemical reagents and highly toxic oxidizers, selecting DN25 minimum flow model and equipped with leak monitoring devices; The entire machine is fully sealed and non-volatile, preventing the volatilization of highly toxic and highly corrosive agents from harming operator safety, suitable for laboratory sample development and precision purification processes.
Specific gravity specification: Standard factory models are only compatible with liquids with a specific gravity ≤ 1.3g/cm³. If the specific gravity of the chemical solution exceeds this value, it must be informed during the ordering stage to customize a high-torque reinforced motor to prevent motor overload and burnout.
Medium particle limitation: This machine only allows the conveying of media containing trace amounts of soft crystals. It is strictly forbidden to transport chemical liquids containing hard particles or large amounts of blocky precipitates. Solid particles can rapidly wear down the silicon carbide/PTFE sliding bearings and fluorine-lined isolation sleeves, causing lining damage and leakage of highly corrosive media.
No idle operation: Before starting, ensure the pump chamber is completely filled with liquid; dry operation without medium is strictly prohibited; When the bearing is running idle without medium lubrication and cooling, it will wear through the fluorine-lined isolation sleeve in a short time, causing major safety incidents such as leakage of highly corrosive and hazardous chemical liquids.
Medium temperature classification: Standard PTFE fluorine-lined complete machine compatible with -30~120°C room temperature corrosive media; If the medium temperature stays close to 120°C for a long time, thicker PTFE liners are needed, as high temperatures accelerate the aging and cracking of FEP materials.
Explosion-proof requirements: When transporting flammable and explosive organic solvents such as acetone, alcohol, and xylene, the entire machine must be equipped with an explosion-proof three-phase motor; Ordinary motors lack explosion-proof protection for wiring and heat dissipation, posing major safety hazards such as static electricity fires and explosions.
Corrosion strength classification: For highly corrosive media such as hydrofluoric acid, chromic acid, and aqua regia, a fully fluorine-lined PTFE configuration must be used with silicon carbide wear-resistant bearings. FRPP and ordinary stainless steel cannot withstand such media, leading to corrosion, perforation, and leakage within a short time.
