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, which is generally consistent with the inlet pipe diameter.
2. Nominal pressure:
Determine the pressure rating of the filter according to the highest possible pressure in the filter line.
3. Selection of hole number:
The main consideration is the particle size of impurities to be intercepted, which is determined according to the process requirements of the media process. Check the table "Filter Specifications" for the particle sizes that various specifications of wire mesh can intercept.
4. Filter material:
The material of the filter is generally selected 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. Calculation of filter resistance loss
For water filters, under the generally calculated rated flow rate, the pressure loss is 0.52~1.2kpa
