4. Maximum Ambient Temperature: +40°C
5. Gas-Liquid Ratio: 1:9 (gas suction volume is approximately 8 to 10%)
6. Inlet Orientation: Horizontal; Outlet Orientation: Vertical
Application
1,Ideal for air suspension treatment systems, ozone water preparation, and biological treatment equipment.
2,Perfect for feeding heating or cooling mediums into various temperature regulation devices.
3,Effective in filtering applications: enables suction or high-pressure transfer of low-viscosity liquids from underground tanks, like gasoline and solvents.
4,Efficient in misting treatments of clear water, pure water, food substances, chemical solutions, and waste solutions.
5,Designed for strict applications requiring continuous operation and abrupt hydraulic pressure changes, such as small-scale steam boilers, high-rise water supply, and high-pressure water injection into tanks.
6,Ideal for sampling from rivers or tanks, transferring foamable liquids, and ensuring smooth transfer through long horizontal pipelines prone to air pockets.
1,This pump excels at simultaneous water and gas suction, pressurizing and mixing them internally, creating ultra-fine bubbles (20 to 30 μm), achieving excellent gas-liquid dissolution.
2,Boasts stable performance, high efficiency, and low noise, with gas-liquid dissolution efficiency reaching twice that of traditional methods.
3,In air suspension applications, it reduces the need for air compressors, mixers, and high-pressure air tanks, eliminating instability and large bubble boiling issues.
4,In ozone water preparation systems, it minimizes the need for mixers and large oxidation towers, significantly reducing equipment costs while achieving over 95% gas-liquid dissolution.
5,The pump is straightforward in design and operation, requiring minimal maintenance while offering durability. It has superior self-suction capabilities and a vast range of applications.
