Principles for selecting water filters

1. Import and export diameter:
In principle, the inlet and outlet diameter of the filter should not be smaller than the inlet diameter of the matching pump, and generally consistent with the diameter of the inlet pipeline.
2. Nominal pressure:
Determine the pressure rating of the filter based on the maximum pressure that may occur in the filtering pipeline.
3. Selection of pore size:
The main consideration is the particle size of impurities that need to be intercepted, depending on the process requirements of the medium flow. The particle size that can be intercepted by various specifications of wire mesh can be found in the table "Filter Screen Specifications".
4. Filter material:
The material of the filter is generally chosen to be the same as the material of the connected process pipeline. For different service conditions, filters made of cast iron, carbon steel, low-alloy steel, or stainless steel can be considered.
5. Filter resistance loss calculation
At the rated flow rate, the pressure loss of a water filter is generally calculated to be 0.52-1.2kpa.
