To choose the right filter, we should pay attention to several aspects.

1. Material of filter:

The material of the filter is generally the same as that of the process carbon steel filter pipe connected to it. For different service conditions, filters made of cast iron, carbon steel, low alloy steel or stainless steel can be selected.

2. Nominal pressure of filter:

The pressure level of the filter is determined according to the maximum pressure that may occur in the filter pipeline.

3. Import and export paths:

In principle, the inlet and outlet diameter of the filter should not be less than the inlet diameter of the pump matched with the stainless steel membrane shell, which is generally the same as the inlet pipe intersection.

4. Calculation of resistance loss of filter

The pressure loss of water filter is 0.52-1.2 kPa under the normal rated flow rate.

5. Selection of the number of holes:

The particle size of the impurities to be intercepted is mainly considered, depending on the technological requirements of the medium process. Various sizes of silk meshes can be intercepted. Look up the "filter mesh specifications" in the table below.
