Dosing pump for analytical instrumentation The compact micro annular gear pump mzr-2921X1 of the low pressure series is an innovative pump concept for use in analytical instrumentation. 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 small dimensions are the characteristics of this variant of the low pressure series. The pump is suitable for dosage of low viscosity liquids such as deionized water, watery solutions, methanol, solvents, oil and lubricants. Advantages Small dosage volumes, high flow rates smallest volume 0.5 µl – flow up to 18 ml/min High dosage precision precision CV 1 % at low volumes Integrated motion controller Programmable motor control for speed and position control with RS-232 interface Long service life wear-resistant tungsten carbide or ceramics Low pulsation delivery, low shear stress rotary micro annular gear technology
