Functional module for mzr-pumps of the low pressure and magnetic hermetic series

The filter-pump-valve functional module F-P-V allows the combination of micro annular gear pump, filter and valve with short direct connections for precise and reproducible dosing. The void volume of this compact system is low and the expenses of connecting elements are obsolete. The integrated wire mesh filter with a mesh size of 10 µm preventatively protects the pump as well as the downstream fluidic micro structures from contamination with particles. Replacement of the easily accessible filter is uncomplicated, removing the pump is unnecessary. The functional module can be used flexibly for several sizes of pumps of the low pressure and magnetic hermetic pump series. Compared to the basic module F-P the module format F-P-V features a small, chemically resistant 2/2- or 3/2-way shift valve, used for the almost backstroke free blockage of the fluid line to prevent the backflow of fluid through the pump. This functional module is especially well-suited for highly precise discrete dosing in aspirate and dispense mode.
