HNP-Mikrosysteme - Model MZR - 2521 -Compact Low Pressure Micro Annular Gear Pump
The compact micro annular gear pump mzr-2521 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.
