Non-pulsating, contamination-free, and high viscosity! A pump that adopts a unique sine curve theory.

The "Sign Pump" is a volumetric pump that incorporates a smooth and gentle curve known as the "sine curve" into its rotor (rotating blades). This innovative form brings the pump's performance as close to ideal as possible. It is suitable for transferring liquids with low to high viscosity, as well as for transferring liquids that are prone to physical damage. Additionally, it produces minimal pulsation, with almost no fluctuations in pressure or flow rate. 【Features】 ○ Can transfer "solid materials without breaking" and maintain texture ○ "No shear" applied, ensuring delicate liquids retain their properties ○ Unique sine curve theory minimizes "pulsation" ○ Capable of transferring "ultra-high viscosity" liquids up to 1,000,000 mPa.s ○ "Easy maintenance" designed with user-friendliness in mind For more details, please contact us or download the catalog. *Please also check out our new CIP/SIP compatible Sign Pump series product, "Certa."
