Import and export path
In principle, the inlet and outlet diameter of the filter should not be less than the inlet diameter of the matching pump, which is generally consistent with the diameter of the inlet pipe.
Nominal pressure
The pressure rating of the filter is determined by the highest pressure that may occur in the filter line.
Choice of the number of holes
The main consideration is the particle size of the impurities to be intercepted, depending on the process requirements of the media process. The size of the screen that can be intercepted by various specifications of the screen can be found in the table below.
Filter material
The material of the filter is generally chosen to be the same as the material of the connected process pipe. For different service conditions, consider a filter made of cast iron, carbon steel, low alloy steel or stainless steel.
Filter resistance loss calculation
The water filter has a pressure loss of 0.52 to 1.2 kPa at a generally calculated rated flow rate.
