• Vacuum pump

It demonstrates optimal performance for the transfer of all types of liquids, including high-viscosity liquids, high-concentration liquids, low-viscosity liquids, low-concentration liquids, liquids containing solid particles, and slurry water. Compared to other pumps from different manufacturers with the same screw rotor diameter, this pump has a discharge capacity that is 1.5 to 6 times greater, allowing for operation at low rotational speeds. With a lower screw peripheral speed, it is very advantageous against stator wear, resulting in a longer lifespan for consumable parts.

• Vacuum pump

This product is an air Roots blower that dramatically enhances energy-saving performance, widely used in public water treatment processes and similar applications. As a volumetric blower manufacturer, we aimed to differentiate ourselves from competitors by focusing on compactness, low noise, and a thorough pursuit of energy efficiency. We achieved this through a unique impeller shape called "RiS-brid curve," which minimizes backflow from the non-contact rotational gap, along with high-precision processing technology and optimization of rotational speed. As a result, we have achieved the industry's top volumetric efficiency for Roots blowers and approximately 30% better energy-saving performance compared to equivalent models from other companies!

• others
