Metal-free pump

The micro annular gear pump mzr-2942X1-cp of the modular pump series is designed as a metal-free pump. To guarantee maximum chemical resistance, the rotors and all wetted components are made of state-of-the-art materials, such as the high-performance plastic PEEK or various ceramics. All wetted components, including the sealing components, are FDA-compliant. The pump generates a low pulsation, highly precise flow featuring low shear stress. It dispenses at a high precision the lowest volumes in microliter range. The compact design with a brushless motor as well as an integrated motion controller for speed and position control are further characteristics of this pump variant. The pump is suitable for the life science and laboratory analysis sectors and for all other fields of application where low pressures and low viscosities are used for dosing or continuous flow of liquid media. For optimum cleaning, the pump is available as a special design with a flushing module.
