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

The filter-pump functional module F-P allows the combination of micro annular gear pump and filter with short direct connections. 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 and downstream fluidic micro structures from contamination with particles. Replacement of the easy accessible filter is uncomplicated, removing of 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. The modules can ideally be used for precise and reliable discrete and continuous dosing of volume flows from 0.15 to 72 ml/min. Applications in the field of analytical instrumentation, medical engineering and micro reaction technology as well as other.
