HNP Mikrosysteme MZR Low Pressure Series Internal Gear Pump for pumping low viscosity fluids at low
pressures
HNPM also offer a by-pass module for their pumps which enables constant small flow rates in the microlitre and nanolitre ranges to be achieved. The technology bases on the partitioning of a volume flow according to the relationship of the fluidic resistance of two capillaries. The volume flow is generated by a micro annular gear pump
Flow rate 1 µl/h up to 10 ml/hr
Differential pressure range 0 - 3 bar
Pulsation free delivery
For use with micro annular gear pumps mzr-2521, 2921 and 4622
