A chemical pump is a high-performance pump specifically designed for transporting corrosive media such as strong acids, strong alkalis, and organic solvents, playing a crucial role in modern industrial systems. From chemical liquid dosing and electroplating solution circulation to wastewater treatment agent transportation, and chemical control in photovoltaics, batteries, and new energy sources, chemical pumps are used in almost all scenarios requiring precise and safe transportation of chemical liquids. As production processes increasingly demand higher precision, safety, and stability, a reliable chemical pump has become a vital foundation for ensuring quality, controlling costs, and improving efficiency in industrial systems.
Our chemical pumps are designed with "high precision, corrosion resistance, long lifespan, maintenance-free operation, and intelligent control." Through advanced structural design and high-performance materials, they achieve long-term stable operation and are suitable for various complex working conditions.
I. Working Principle and Structural Highlights of the Chemical Pump
The core principle of a chemical pump is to use the reciprocating motion of a diaphragm or plunger to draw liquid into the pump chamber and discharge it quantitatively, achieving high-precision transportation. Compared to traditional transfer pumps, chemical pumps prioritize sealing, chemical resistance, and precise control in their structural design. Key structural features include:
1. Diaphragm-driven structure, naturally leak-proof design
The diaphragm completely isolates the liquid from the mechanical components, preventing contact between the medium and moving parts, thus eliminating leakage at the source.
This design is ideal for conveying hazardous chemicals such as sulfuric acid, nitric acid, sodium hydroxide, sodium hypochlorite, and electrolytes.
2. High corrosion-resistant materials ensure long-term stability
Wetted parts can be made of:
PTFE: Resistant to strong acids and alkalis
PVDF: Resistant to highly corrosive media and high-purity water
SS316L: Resistant to moderate corrosion and industrial applications
This material combination makes it suitable for over 90% of chemical liquid applications.
3. Optimized hydraulic end structure, less pulsation, and more stable flow
Through optimized flow channels, improved valve seats, and an isochoric pump chamber design, the output is more stable, improving dosing accuracy and extending system lifespan.
