Pump for precise filling and dosing technology

Micro annular gear pump mzr-11540 of the modular pump series operates with high dynamics, low pulsation and excellent precision in delivery as well as high repeatability in metering. The pump is suitable for low to high viscosity liquids and a dif-ferential pressure of up to 15 bar. It allows accurate displacement volumes starting at 100 µl in a metering time of 200 milliseconds. It also covers a flow rate range of 0.2 to 1,152 ml/min. The pump comes with lateral fluid connections or with a manifold version with frontal fluid connections.
