KTM Karyu Turbo Mixer

Nikuni Micro-Bubble Generator

www.nikunijapan.com

Features :1. Three Functions in One Pump

- The KTM simultaneously draws in air and water, dissolves air with its turbine impeller, and pumps pressurized water to the flotation tank or other process

2. Highly Efficient Air-water Dissolution- Precision turbine pump technology and a unique design

make possible extremely high levels of efficiency in dissolving air into water

3. Simplified DAF Operation and Stable Pump Performance- The multifunctional KTM eliminates the need for ancillary

equipment such as air compressors, large saturation tanks with difficult level control, and truly simplifies DAF systems and their operation

4. Compact and Small Footprint- Easily retrofit or upgrade existing DAF systems

5. Minimal Power Consumption and Maintenance cost- Highly efficient process with small pump and motor, no

compressor power required, while the simple and robust structure of the KTM minimizes maintenance cost

“Suction, Mixing/Dissolving, and Pressurization” with just a single KTM!
