The operation is quiet, the liquid does not foam, and it is highly efficient with a long lifespan! It is easy to transport high-viscosity liquids or achieve high-speed rotation.
The "Elicroid Gear" is a continuously curved gear with a single point of contact, developed specifically for fluid transport pumps. It has high transmission efficiency, incorporates a great degree of design freedom, and is easy to manufacture. The discharge volume and torque remain constant at any moment of rotation, eliminating the causes of vibration and noise. By having no trapped volume and increasing the tooth module to reduce the number of teeth, it is easy to maintain a very high vacuum efficiency of 80% even at a vacuum of 700 mmHg. 【Features】 ■ No trapping phenomenon ■ Easy transport of high-viscosity liquids or high-speed rotation ■ Discharge volume and torque remain constant at any moment of rotation ■ Does not cause issues due to wear ■ No restrictions on the minimum number of teeth *For more details, please refer to the PDF materials or feel free to contact us.
