HNP Mikrosysteme always recommends the use of a filter with a pore size or mesh width of 10 µm to protect the micro annular gear pump. Straight inline filters and inline T-filters as well as inlet filters made of various materials with different filter surfaces are offered. Our filters can be ordered separately as single product.

Also, it is possible to implement a sensor for filter monitoring. This allows to detect pending maintenance or cleaning of the filter as well as a closed supply line. In the »T-version« the sensor is directly adaptable, for straight filters it can be integrated by adding a separate mounting block.
