Our recommended filtration for the Piston series is 5 or 10 micron, for the Gear series it is 15 and 30 micron and for the helical rotor series the recommendation is 150 micron (100 mesh). For high viscosity fluids, you may have to loosen this specification to maintain an acceptable pressure drop in your system. Please consider the tight tolerances within the meter and possible sources of contamination. If dirt is present in your process, the recommended filtration level should be maintained.
Max offers filter assemblies with replaceable mesh kits. See our filter and filter element section
