HNPM mzr-2521 Low Pressure Micro Annular Gear Pump from HNP Mikrosysteme supplied by Thomson Process Equipment and Engineering Ltd.
HNP Mikrosysteme compact micro annular gear pump mzr-2521 Low Pressure Pump for use in Analytical Instrumentation.
HNPM mzr-2521 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 of the HNPM mzr-2521 Micro Annular Gear Pump.
- Compact dimensions - diameter 13 mm, length 75 mm
- Small dosage volumes, high flow rates - smallest volume 0.25 µl, flow up to 9 ml/min
- High dosage precision - precision CV 1 % at low volumes
- Long service life - wear-resistant tungsten carbide or ceramics
- Low pulsation delivery, low shear stress - rotary micro annular gear technology
Applications of the HNP Mikrosysteme HNPM mzr-2521 Micro Annular Gear Pump Low Pressure Series.
