Dosing pump for analytical instrumentation The compact micro annular gear pump mzr-4622 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. Due to its compact design small dimensions have been achieved. The pump is suitable for dosage of low viscosity liquids such as deionized water, watery solutions, methanol, solvents, oil and lubricants. Advantages Compact dimensions diameter 18 mm, length 88 mm Small dosage volumes, high flow rates smallest volume 2 µl – flow up to 72 ml/min High dosage precision precision CV 1 % at low volumes Long service life wear-resistant tungsten carbide Low pulsation delivery, low shear stress
