1, Import and export Path: Import and export filters principle diameter should not be less than the matching pump inlet diameter, generally consistent with the import pipeline diameter. 2, Nominal pressure: Determine the filter in accordance with the maximum pressure rating of the pressure filter pipe may occur. 3, The choice of mesh hole: The main consideration for an intercept impurities particle size, according to media process technology requirements. A variety of particle size of the screen can be blocked check under the table “filter specifications.” 4, The filter material: The filter material generally choose the connection process piping with the same material for different service conditions may consider choosing cast iron, carbon steel, low alloy steel or stainless steel filter. 5, Filter resistance loss calculation Water filter, in general computing nominal flow rate, pressure loss of 0.52 ~ 1.2kpa
